6b5a2b7d9b Merge tag 'trace-tools-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace 
Pull RTLA tool updates from Steven Rostedt:

 - Fix discrepancy in --dump-tasks option

   Due to a mistake, rtla-timerlat-hist used the CLI syntax
   "--dump-task" instead of the documented "--dump-tasks". Change the
   option to match both documentation and the other timerlat tool,
   rtla-timerlat-top.

 - Extend coverage of runtime tests

   Cover both top and hist tools in all applicable test cases, add tests
   for a few uncovered options, and extend checks for some existing
   tests.

 - Add unit tests for actions

   rtla's actions feature is implemented in its source file and contains
   non-trivial parsing logic. Cover it with unit tests.

 - Stop record trace on interrupt

   Fix a bug where an interval exists after receiving a signal in which
   the main instance is stopped but the record instance is not, leading
   to discrepancies in reported results and sometimes rtla hanging.

 - Restore continue flag in actions_perform()

   Fix a bug where rtla always continues tracing after hitting a
   threshold even if the continue action was triggered just once, and
   add tests verifying that the flag is reset properly.

 - Migrate command line interface to libsubcmd

   Replace rtla's argument parsing using getopt_long() with libsubcmd,
   used by perf and objtool, to reuse existing code and auto-generate
   better help messages. Extensive unit tests are included to detect
   regressions.

 - Add -A/--aligned option to timerlat tools

   Add an option to align timerlat threads, based on the recently
   introduced TIMERLAT_ALIGN option of the timerlat tracer, together
   with unit tests and documentation.

 - Document tests in README

   Document how to run unit and runtime tests in rtla's README.txt,
   including the dependencies needed to run them.

18ecdd4d0a Merge tag 'probes-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace 
Pull probes updates from Masami Hiramatsu:

 - BTF support for dereferencing pointers

   Add syntax to the parsing of eprobes to typecast structure pointer
   trace event fields, enabling BTF-based dereferencing instead of
   relying on manual offsets.

 - Improvements and robustness enhancements

    - Use flexible array for entry fetch code.

      Store probe entry fetch instructions in the probe_entry_arg
      allocation via a flexible array member to simplify memory
      allocation and lifetime management.

    - Replace BUG_ON with lockdep_assert_held in uprobe_buffer functions

      Replace BUG_ON() calls with lockdep_assert_held() in uprobe buffer
      enable/disable paths to prevent kernel crashes and better verify
      lock ownership.

    - Ensure the uprobe buffer size is bigger than event size.

      Add a BUILD_BUG_ON() assertion to guarantee that the per-CPU
      uprobe working buffer size is always larger than the maximum probe
      event size.

 "There's one new driver, one legacy driver removed, a kunit test-suite
  for the GPIO core, support for new models in existing drivers and a
  slew of various changes in many places though I can't think of
  anything controversial that would stand out - it's been a relatively
  calm cycle.

  GPIO core:

     fwnode_gpiod_get()
   - Quarantine all legacy GPIO APIs in linux/gpio/legacy.h
   - Use __ro_after_init where applicable

  New drivers:
   - Add driver for the GPIO controller on Waveshare DSI TOUCH panels

     arrays
   - Convert gpio-altera to using the generic GPIO chip helper library
   - Add support for new models to gpio-dwapb, gpio-zynq, gpio-usbio and
     gpio-tegra186
   - Unify the naming convention for Qualcomm in GPIO drivers
   - Fix interrupt bank mapping to GPIO chips in gpio-mt7621
   - Add support for the lines-initial-states property to gpio-74x164

   - Move the handling of an OF quirk from ASoC to gpiolib-of.c where
     other such quirks live
   - Use handle_bad_irq() in gpio-ep93xx
   - Some other minor tweaks and refactorings

  Devicetree bindings:

Pull arm64 updates from Will Deacon:
 "It feels like the new world of AI tooling has slowed us down a little
  on the feature side when compared to the fixes side. The extra rounds
  of Sashiko review have also pushed a few things out until next time.

  Still, there's some good foundational stuff here for the fpsimd code
  and hardening work towards removing the predictable linear alias of
  the kernel image.

  CPU errata handling:
   - Extend CnP disabling workaround to HiSilicon HIP09 hardware.
   - Work around eternally broken broadcast TLB invalidation on more
     CPUs.
   - Documentation and code cleanups.

  CPU features:
   - Add new hwcaps for the 2025 dpISA extensions.

  Floating point / SVE / SME:
   - Significant cleanup to the low-level state management code in the
     core architecture code and KVM.
   - Use correct register widths during SVE/SME save/restore assembly.
   - Expose SVE/SME save/restore memory accesses to sanitisers.

  Memory management:
   - Preparatory work for unmapping the kernel data and bss sections
     from the linear map.

  Miscellaneous:
   - Inline DAIF manipulation helpers so they can be used safely from
     non-instrumentable code.
   - Fix handling of the 'nosmp' cmdline option to avoid marking
     secondary cores as "possible".

  MPAM:
   - Add support for v0.1 of the MPAM architecture.

  Perf:
   - Update HiSilicon PMU MAINTAINERS entry.
   - Fix event encodings for the DVM node in the CMN driver.

  Selftests:
   - Extend sigframe tests to cover POE context.
   - Add coverage for the newly added 2025 dpISA hwcaps.

  System registers:
   - Add new registers and ESR encodings for the HDBSS feature.

  Plus minor fixes and cleanups across the board"

 "Futex updates:

   - Optimize futex hash bucket access patterns (Peter Zijlstra)

   - Large series to address the robust futex unlock race for real, by
     Thomas Gleixner:

      "The robust futex unlock mechanism is racy in respect to the
       clearing of the robust_list_head::list_op_pending pointer because
       unlock and clearing the pointer are not atomic.

       The race window is between the unlock and clearing the pending op
       pointer. If the task is forced to exit in this window, exit will
       access a potentially invalid pending op pointer when cleaning up
       the robust list.

       That happens if another task manages to unmap the object
       containing the lock before the cleanup, which results in an UAF.

       In the worst case this UAF can lead to memory corruption when
       unrelated content has been mapped to the same address by the time
       the access happens.

       User space can't solve this problem without help from the kernel.
       This series provides the kernel side infrastructure to help it
       along:

        1) Combined unlock, pointer clearing, wake-up for the
           contended case

        2) VDSO based unlock and pointer clearing helpers with a
           fix-up function in the kernel when user space was interrupted
           within the critical section.

   - Pass KBUILD_MODNAME through the platform driver registration macro
     to create module symlinks in sysfs for built-in drivers; move
     module_kset initialization to a pure_initcall and tegra cbb
     registration to core_initcall to ensure correct ordering
   - Pass THIS_MODULE implicitly through a coresight_init_driver() macro

  sysfs:
   - Upgrade OOB write detection in sysfs_kf_seq_show() from printk to
     WARN
   - Add return value clamping to sysfs_kf_read()

  Rust:
   - ACPI:

     Fix missing match data for PRP0001 by exporting
     acpi_of_match_device()

   - Auxiliary:

     Replace drvdata() with dedicated registration data on
     auxiliary_device. drvdata() exposed the driver's bus device private
     data beyond the driver's own scope, creating ordering constraints
     and forcing the data to outlive all registrations that access it.
     Registration data is instead scoped structurally to the
     Registration object, making lifecycle ordering enforced by
     construction rather than convention.

   - Rust-native device driver lifetimes (HRT):

     Allow Rust device drivers to carry a lifetime parameter on their
     bus device private data, tied to the device binding scope -- the
     interval during which a bus device is bound to a driver. Device
     resources like pci::Bar<'a> and IoMem<'a> can be stored directly in
     the driver's bus device private data with a lifetime bounded by the
     binding scope, so the compiler enforces at build time that they do
     not outlive the binding. This removes Devres indirection from every
     access site and eliminates try_access() failure paths in
     destructors.

     Bus driver traits use a Generic Associated Type (GAT) Data<'bound>
     to introduce the lifetime on the private data, rather than
     parameterizing the Driver trait itself. Auxiliary registration
     data, where the lifetime is not introduced by a trait callback but
     must be threaded through Registration, uses the ForLt trait (a
     type-level abstraction for types generic over a lifetime).

  Misc:
   - Fix DT overlayed devices not probing by reverting the broken
     treewide overlay fix and re-running fw_devlink consumer pickup when
     an overlay is applied to a bound device
   - Use root_device_register() for faux bus root device; add sanity
     check for failed bus init
   - Fix dev_has_sync_state() data race with READ_ONCE() and move it to
     base.h
   - Avoid spurious device_links warning when removing a device while
     its supplier is unbinding
   - Switch ISA bus to dynamic root device
   - Fix suspicious RCU usage in kernfs_put()
   - Remove devcoredump exit callback
   - Constify devfreq_event_class"

Pull Rust updates from Miguel Ojeda:
 "This one is big due to the vendoring of the `zerocopy` library, which
  allows us to replace a bunch of `unsafe` code dealing with conversions
  between byte sequences and other types with safe alternatives. More
  details on that below (and in its merge commit).

  Toolchain and infrastructure:

   - Introduce support for the 'zerocopy' library [1][2]:

         Fast, safe, compile error. Pick two.

         Zerocopy makes zero-cost memory manipulation effortless. We write
         `unsafe` so you don't have to.

     It essentially provides derivable traits (e.g. 'FromBytes') and
     macros (e.g. 'transmute!') for safely converting between byte
     sequences and other types. Having such support allows us to remove
     some 'unsafe' code.

     It is among the most downloaded Rust crates and it is also used by
     the Rust compiler itself.

     It is licensed under "BSD-2-Clause OR Apache-2.0 OR MIT".

     The crates are imported essentially as-is (only +2/-3 lines needed
     to be adapted), plus SPDX identifiers. Upstream has since added the
     SPDX identifiers as well as one of the tweaks at my request, thus
     reducing our future diffs on updates -- I keep the details in one
     of our usual live lists [3].

     In total, it is about ~39k lines added, ~32k without counting
     'benches/' which are just for documentation purposes.

     The series includes a few Kbuild and rust-analyzer improvements and
     an example patch using it in Nova, removing one 'unsafe impl'.

     I checked that the codegen of an isolated example function (similar
     to the Nova patch on top) is essentially identical. It also turns
     out that (for that particular case) the 'zerocopy' version, even
     with 'debug-assertions' enabled, has no remaining panics, unlike a
     few in the current code (since the compiler can prove the remaining
     'ub_checks' statically).

     So their "fast, safe" does indeed check out -- at least in that
     case.

   - Support AutoFDO. This allows Rust code to be profiled and optimized
     based on the profile. Tested with Rust Binder: ~13% slower without
     AutoFDO in the binderAddInts benchmark (using an app-launch
     benchmark for the profile).

   - Support Software Tag-Based KASAN.

     In addition, fix KASAN Kconfig by requiring Clang.

   - Add Kconfig options for each existing Rust KUnit test suite, such
     as 'CONFIG_RUST_BITMAP_KUNIT_TEST'.

     They are placed within a new menu, 'CONFIG_RUST_KUNIT_TESTS', in
     the new 'rust/kernel/Kconfig.test' file.

   - Support the upcoming Rust 1.98.0 release (expected 2026-08-20):
     lint cleanups and an unstable flag rename.

   - Disable 'rustdoc' documentation inlining for all prelude items,
     which bloats the generated documentation.

   - Ignore (in Git) and clean (in Kbuild) the (rarely) 'rustc'-generated
     '*.long-type-*.txt' files.

  'kernel' crate:

   - Add new 'bitfield' module with the 'bitfield!' macro (extracted
     from the existing 'register!' one), which declares integer types
     that are split into distinct bit fields of arbitrary length.

     Each field is a 'Bounded' of the appropriate bit width (ensuring
     values are properly validated and avoiding implicit data loss) and
     gets several generated getters and setters (infallible, 'const' and
     fallible) as well as associated constants ('_MASK', '_SHIFT' and
     '_RANGE'). It also supports fields that can be converted from/to
     custom types, either fallibly ('?=>') or infallibly ('=>').

     For instance:

         bitfield! {
             struct Rgb(u16) {
                 15:11 blue;
                 10:5 green;
                 4:0 red;
             }
         }

         // Compile-time checks.
         let color = Rgb::zeroed().with_const_green::<0x1f>();

         assert_eq!(color.green(), 0x1f);
         assert_eq!(color.into_raw(), 0x1f << Rgb::GREEN_SHIFT);

     Add as well documentation and a test suite for it, as usual; and
     update the 'register!' macro to use it.

     It will be maintained by Alexandre Courbot (with Yury Norov as
     reviewer) under a new 'MAINTAINERS' entry: 'RUST [BITFIELD]'.

   - 'ptr' module: rework index projection syntax into keyworded syntax
     and introduce panicking variant.

     The keyword syntax ('build:', 'try:', 'panic:') is more explicit
     and paves the way of perhaps adding more flavors in the future,
     e.g. an 'unsafe' index projection.

     For instance, projections now look like this:

         fn f(p: *const [u8; 32]) -> Result {
             // Ok, within bounds, checked at build time.
             project!(p, [build: 1]);

             // Build error.
             project!(p, [build: 128]);

             // `OutOfBound` runtime error (convertible to `ERANGE`).
             project!(p, [try: 128]);

             // Runtime panic.
             project!(p, [panic: 128]);

             Ok(())
         }

     Update as well the users, which now look like e.g.

         // Pointer to the first entry of the GSP message queue.
         let data = project!(self.0.as_ptr(), .gspq.msgq.data[build: 0]);

   - 'build_assert' module: make the module the home of its macros
     instead of rendering them twice.

   - 'sync' module: add 'UniqueArc::as_ptr()' associated function.

   - 'alloc' module:

       - Fix the 'Vec::reserve()' doctest to properly account for the
         existing vector length in the capacity assertion.

       - Fix an incorrect operator in the 'Vec::extend_with()' 'SAFETY'
         comment; add a doc test demonstrating basic usage and the
         zero-length case.

   - Clean imports across several modules to follow the "kernel
     vertical" import style in order to minimize conflicts.

  'pin-init' crate:

   - User visible changes:

       - Do not generate 'non_snake_case' warnings for identifiers that
         are syntactically just users of a field name. This would allow
         all '#[allow(non_snake_case)]' in nova-core to be removed,
         which Gary will send to the nova tree next cycle.

       - Filter non-cfg attributes out properly in derived structs. This
         improves pin-init compatibility with other derive macros.

       - Insert projection types' where clause properly.

   - Other changes:

       - Bump MSRV to 1.82, plus associated cleanups.

       - Overhaul how init slots are projected. The new approach is
         easier to justify with safety comments.

       - Mark more functions as inline, which should help mitigate the
         super-long symbol name issue due to lack of inlining.

  rust-analyzer:

   - Support '--envs' for passing env vars for crates like 'zerocopy'.

  'MAINTAINERS':

   - Add the following reviewers to the 'RUST' entry:
       - Daniel Almeida
       - Tamir Duberstein
       - Alexandre Courbot
       - Onur Özkan

     They have been involved in the Rust for Linux project for about 7
     collective years and bring expertise across several domains, which
     will be very useful to have around in the future.

     Thanks everyone for stepping up!

  And some other fixes, cleanups and improvements"

Pull procfs updates from Christian Brauner:

 - Revamp fs/filesystems.c

   The file was a mess with a hand-rolled linked list in desperate need
   of a cleanup. The filesystems list is now RCU-ified, /proc files can
   be marked permanent from outside fs/proc/, and the string emitted
   when reading /proc/filesystems is pre-generated and cached instead of
   pointer-chasing and printfing entry by entry on every read.

   The file is read frequently because libselinux reads it and is linked
   into numerous frequently used programs (even ones you would not
   suspect, like sed!). Scalability also improves since reference
   maintenance on open/close is bypassed.

    open+read+close cycle single-threaded (ops/s):
      before: 442732
      after:  1063462 (+140%)

    open+read+close cycle with 20 processes (ops/s):
      before: 606177
      after:  3300576 (+444%)

   A follow-up patch adds missing unlocks in some corner cases and
   tidies things up.

 - Relax the mount visibility check for subset=pid mounts

   When procfs is mounted with subset=pid, all static files become
   unavailable and only the dynamic pid information is accessible. In
   that case there is no point in imposing the full mount visibility
   restrictions on the mounter - everything that can be hidden in procfs
   is already inaccessible. These restrictions prevented procfs from
   being mounted inside rootless containers since almost all container
   implementations overmount parts of procfs to hide certain
   directories.

   As part of this /proc/self/net is only shown in subset=pid mounts for
   CAP_NET_ADMIN, reconfiguring subset=pid is rejected, the
   SB_I_USERNS_VISIBLE superblock flag is replaced with an
   FS_USERNS_MOUNT_RESTRICTED filesystem flag, fully visible mounts are
   recorded in a list, and the mount restrictions are finally
   documented.

 - Protect ptrace_may_access() with exec_update_lock in procfs

   Most uses of ptrace_may_access() in procfs should hold
   exec_update_lock to avoid TOCTOU issues with concurrent privileged
   execve() (like setuid binary execution).

   This fixes the easy cases - the owner and visibility checks and the
   FD link permission checks - with the gnarlier ones to follow later.

Pull misc vfs updates from Christian Brauner:
 "Features:

   - Reduce pipe->mutex contention by pre-allocating pages outside the
     lock in anon_pipe_write().

     anon_pipe_write() called alloc_page() once per page while holding
     pipe->mutex. The allocation can sleep doing direct reclaim and runs
     memcg charging, which extends the critical section and stalls any
     concurrent reader on the same mutex. Now up to 8 pages are
     pre-allocated before the mutex is taken, leftovers are recycled
     into the per-pipe tmp_page[] cache before unlock, and any remainder
     is released after unlock, keeping the allocator out of the critical
     section on both sides. On a writers x readers sweep with 64KB
     writes against a 1 MB pipe throughput improves 6-28% and average
     write latency drops 5-22%; under memory pressure - when the cost of
     holding the mutex across reclaim is highest - throughput improves
     21-48% and latency drops 17-33%. The microbenchmark is added to
     selftests.

   - uaccess/sockptr: fix the ignored_trailing logic in
     copy_struct_to_user() to behave as documented and the usize check
     in copy_struct_from_sockptr() for user pointers, and add
     copy_struct_{from,to}_bounce_buffer() and copy_struct_to_sockptr()
     helpers for upcoming users (IPPROTO_SMBDIRECT, IPPROTO_QUIC).

   - bpf: add a sleepable bpf_real_inode() kfunc that resolves the real
     inode backing a dentry via d_real_inode(). On overlayfs the inode
     attached to the dentry doesn't carry the underlying device
     information; this is used by the filesystem restriction BPF program
     that was merged into systemd.

   - docs: add guidelines for submitting new filesystems, motivated by
     the maintenance burden abandoned and untestable filesystems impose
     on VFS developers, blocking infrastructure work like folio
     conversions and iomap migration.

  Fixes:

   - libfs: set SB_I_NOEXEC and SB_I_NODEV by default in init_pseudo()
     and drop the now-redundant assignments in callers. This began as a
     one-line dma-buf fix for a path_noexec() warning; a pseudo
     filesystem has no reason not to set SB_I_NOEXEC. All init_pseudo()
     callers were audited: the only visible effect is on dma-buf where
     SB_I_NOEXEC silences the warning.

   - Handle set_blocksize() failures in legacy filesystems (bfs, hpfs,
     qnx4, jfs, befs, affs, isofs, minix, ntfs3, omfs). Mounting a
     device with a sector size > PAGE_SIZE crashed roughly half of them;
     the rest had the same missing error handling pattern. Plus a
     follow-up releasing the superblock buffer_head when setting the
     minix v3 block size fails.

   - mount: honour SB_NOUSER in the new mount API.

   - fs/fcntl: fix a SOFTIRQ-unsafe lock order in fasync signaling by
     switching the process-group paths of send_sigio() and send_sigurg()
     from read_lock(&tasklist_lock) to RCU, matching the single-PID
     path.

   - vfs: add an FS_USERNS_DELEGATABLE flag and set it for NFS, fixing
     delegated NFS mounts (fsopen() in a container with the mount
     performed by a privileged daemon) that broke when non-init
     s_user_ns was tied to FS_USERNS_MOUNT.

   - selftests/namespaces: fix a hang in nsid_test where an unreaped
     grandchild kept the TAP pipe write-end open, a waitpid(-1) race in
     listns_efault_test, and a false FAIL on kernels without listns()
     where the tests should SKIP.

   - filelock: fix the break_lease() stub signature for
     CONFIG_FILE_LOCKING=n.

   - init/initramfs_test: wait for the async initramfs unpacking before
     running; the test and do_populate_rootfs() share the parser state.

   - fs/coredump: reduce redundant log noise in
     validate_coredump_safety().

   - iomap: pass the correct length to fserror_report_io() in
     __iomap_write_begin().

   - backing-file: fix the backing_file_open() kerneldoc.

  Cleanups:

   - initramfs: refactor the cpio hex header parsing to use hex2bin()
     instead of the hand-rolled simple_strntoul() which is reverted, and
     extend the initramfs KUnit tests to cover header fields with 0x
     prefixes.

   - Replace __get_free_pages() and friends with kmalloc()/kzalloc()
     across quota, proc, ocfs2/dlm, nilfs2, nfs, nfsd, libfs, jfs, jbd2,
     isofs, fuse, select, namespace, configfs, binfmt_misc, bfs, and the
     do_mounts init code - part of the larger work of replacing page
     allocator calls with kmalloc().

   - Use clear_and_wake_up_bit() in unlock_buffer() and
     journal_end_buffer_io_sync() instead of open-coding the sequence.

   - Drop unused VFS exports: unexport drop_super_exclusive(), remove
     start_removing_user_path_at(), and fold __start_removing_path()
     into start_removing_path().

   - fs/read_write: narrow the __kernel_write() export with
     EXPORT_SYMBOL_FOR_MODULES().

   - vfs: uapi: retire octal and hex constants in favor of (1 << n) for
     the O_ flags. Finding a free bit for a new flag across the
     architectures was needlessly hard with the mixed bases.

   - dcache: add extra sanity checks of dead dentries in dentry_free()
     via a new DENTRY_WARN_ONCE() that also prints d_flags.

   - iov_iter: use kmemdup_array() in dup_iter() to harden the
     allocation against multiplication overflow.

   - fs/pipe: write to ->poll_usage only once.

   - vfs: remove an always-taken if-branch in find_next_fd().

   - dcache: use kmalloc_flex() for struct external_name in __d_alloc().

   - namei: use QSTR() instead of QSTR_INIT() in path_pts().

   - sync_file_range: delete dead S_ISLNK code.

   - Comment fixes: retire a stale comment in fget_task_next() and fix
     assorted spelling mistakes"

Pull buffer_head updates from Christian Brauner:
 "This removes b_end_io from struct buffer_head.

  Instead of setting bio->bi_end_io to end_bio_bh_io_sync() which then
  calls bh->b_end_io(), the new bh_submit() and __bh_submit() interfaces
  set bio->bi_end_io to the appropriate completion handler directly,
  replacing two indirect function calls in the completion path with one.
  It is also one fewer function pointer in the middle of a writable data
  structure that can be corrupted, it shrinks struct buffer_head from
  104 to 96 bytes allowing roughly 7% more buffer_heads to be cached in
  the same amount of memory, and it removes some atomic operations as
  the buffer refcount is no longer incremented before calling the end_io
  handler.

 - Fix a race between cpufreq suspend and CPU hotplug during system
   shutdown (Tianxiang Chen)

 - Avoid redundant target() calls for unchanged limits and fix a typo
   in a comment in the cpufreq core (Viresh Kumar)

 - Fix concurrency issues related to sysfs attributes access that affect
   cpufreq governors using the common governor code (Zhongqiu Han)

 - Simplify frequency limit handling in the conservative cpufreq
   governor (Lifeng Zheng)

 - Fix descriptions of the conservative governor freq_step tunable and
   the ondemand governor sampling_down_factor tunable in the cpufreq
   documentation (Pengjie Zhang)

 - Fix use-after-free and double free during _OSC evaluation in the PCC
   cpufreq driver (Yuho Choi)

 - Rework the handling of policy min and max frequency values in the
   cpufreq core to allow drivers to specify special initial values for
   the scaling_min_freq and scaling_max_freq sysfs attributes (Pierre
   Gondois)

 - Add cpufreq scaling support for Qualcomm Shikra SoC (Taniya Das,
   Imran Shaik).

 - Improve the warning message on HWP-disabled hybrid processors printed
   by the intel_pstate driver and sync policy->cur during CPU offline in
   it (Yohei Kojima, Fushuai Wang)

 - Drop cpufreq support for AMD Elan SC4* (Sean Young)

 - Minor fixes for cpufreq drivers (Krzysztof Kozlowski, Akashdeep Kaur,
   Hans Zhang, Guangshuo Li, Xueqin Luo)

 - Clean up dead dependencies on X86 in the cpufreq Kconfig (Julian
   Braha)
