99845faae7 drm: document better that drivers shouldn't use drm_minor directly
The documentation for struct drm_minor already states this, but that's
not always that easy to find.

Also due to historical reasons we still have the minor-centric
interfaces (like drm_debugfs_create_files), but since this is now
getting fixed we can put a few more pointers in place as to how this
should be done ideally. Note that debugfs isn't there yet for all
cases (debugfs files on kms objects like crtc/connector aren't
supported, neither debugfs files with full fops), so the debugfs side
of this is still rather aspirational and more for new users than
converting everything existing. todo.rst covers the additional work
needed already.

Motivated by some discussion with Rodrigo on irc about how drm/xe
should lay out its sysfs interfaces.

v2: Make the debugfs situation clearer in the commit message, but
don't elaborate more in the actual kerneldoc to avoid distracting from
the main message around sysfs (Jani)

Also fix some typos.

a9015ce593 drm/mipi-dsi: Add a mipi_dsi_dcs_write_seq() macro
Many panel drivers define dsi_dcs_write_seq() and dsi_generic_write_seq()
macros to send DCS commands and generic write packets respectively, with
the payload specified as a list of parameters instead of using arrays.

There's already a macro for the former, introduced by commit 2a9e9daf75
("drm/mipi-dsi: Introduce mipi_dsi_dcs_write_seq macro") so drivers can be
changed to use that. But there isn't one yet for the latter, let's add it.

c8268795c9 drm/probe-helper: enable and disable HPD on connectors
Introduce two drm_connector_helper_funcs: enable_hpd() and disable_hpd().
They are called by drm_kms_helper_poll_enable() and
drm_kms_helper_poll_disable() (and thus drm_kms_helper_poll_init() and
drm_kms_helper_poll_fini()) respectively.

This allows DRM drivers to rely on drm_kms_helper_poll for enabling and
disabling HPD detection rather than doing that manually.

b357e7ac1b drm/fourcc: Document open source user waiver
It's a bit a FAQ, and we really can't claim to be the authoritative
source for allocating these numbers used in many standard extensions
if we tell closed source or vendor stacks in general to go away.

Iirc this was already clarified in some vulkan discussions, but I
can't find that anywhere anymore. At least not in a public link.

29fca6d56d drm/format-helper: Simplify drm_fb_build_fourcc_list()
The DRM helper drm_fb_build_fourcc_list() creates a list of color
formats for primary planes of the generic drivers. Simplify the helper:

 - It used to mix and filter native and emulated formats as provided
   by the driver. Now the only emulated format is XRGB8888, which is
   required as fallback by legacy software. Drop support for emulating
   any other formats.
 - Also convert alpha formats to their non-alpha counterparts. Generic
   drivers don't support primary planes with alpha formats and some
   DTs incorrectly advertise alpha channels for non-alpha hardware. So
   only export non-alpha formats for primary planes.

With the simplified helper, scrap format lists of the affected generic
drivers. All they need is the firmware buffer's native format, from which
the helper creates the list of color formats.

99cb0d917f arch: fix broken BuildID for arm64 and riscv
Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux
since commit 994b7ac169 ("arm64: remove special treatment for the
link order of head.o").

The issue is that the type of .notes section, which contains the BuildID,
changed from NOTES to PROGBITS.

Ard Biesheuvel figured out that whichever object gets linked first gets
to decide the type of a section. The PROGBITS type is the result of the
compiler emitting .note.GNU-stack as PROGBITS rather than NOTE.

While Ard provided a fix for arm64, I want to fix this globally because
the same issue is happening on riscv since commit 2348e6bf44 ("riscv:
remove special treatment for the link order of head.o"). This problem
will happen in general for other architectures if they start to drop
unneeded entries from scripts/head-object-list.txt.

Discard .note.GNU-stack in include/asm-generic/vmlinux.lds.h.

6f99ac04c4 nvme: consult the CSE log page for unprivileged passthrough
Commands like Write Zeros can change the contents of a namespaces without
actually transferring data.  To protect against this, check the Commands
Supported and Effects log is supported by the controller for any
unprivileg command passthrough and refuse unprivileged passthrough if the
command has any effects that can change data or metadata.

Note: While the Commands Support and Effects log page has only been
mandatory since NVMe 2.0, it is widely supported because Windows requires
it for any command passthrough from userspace.

These are (uint64_t)-1 magic values are a userspace ABI, allowing the
shared info pages and other enlightenments to be disabled. This isn't
a Xen ABI because Xen doesn't let the guest turn these off except with
the full SHUTDOWN_soft_reset mechanism. Under KVM, the userspace VMM is
expected to handle soft reset, and tear down the kernel parts of the
enlightenments accordingly.

1c9cacbea8 drm/debugfs: create device-centered debugfs functions
Introduce the ability to track requests for the addition of DRM debugfs
files at any time and have them added all at once during
drm_dev_register().

Drivers can add DRM debugfs files to a device-managed list and, during
drm_dev_register(), all added files will be created at once.

Now, the drivers can use the functions drm_debugfs_add_file() and
drm_debugfs_add_files() to create DRM debugfs files instead of using the
drm_debugfs_create_files() function.

222882c2ab Merge tag 'random-6.2-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull more random number generator updates from Jason Donenfeld:
 "Two remaining changes that are now possible after you merged a few
  other trees:

   - #include <asm/archrandom.h> can be removed from random.h now,
     making the direct use of the arch_random_* API more of a private
     implementation detail between the archs and random.c, rather than
     something for general consumers.

   - Two additional uses of prandom_u32_max() snuck in during the
     initial phase of pulls, so these have been converted to
     get_random_u32_below(), and now the deprecated prandom_u32_max()
     alias -- which was just a wrapper around get_random_u32_below() --
     can be removed.

  In addition, there is one fix:

   - Check efi_rt_services_supported() before attempting to use an EFI
     runtime function.

     This affected EFI systems that disable runtime services yet still
     boot via EFI (e.g. the reporter's Lenovo Thinkpad X13s laptop), as
     well systems where EFI runtime services have been forcibly
     disabled, such as on PREEMPT_RT.

     On those machines, a very early and hard to diagnose crash would
     happen, preventing boot"

Convert the final two users of prandom_u32_max() that slipped in during
6.2-rc1 to use get_random_u32_below().

Then, with no more users left, we can finally remove the deprecated
function.

08f65892c5 net: simplify sk_page_frag
Now that in-kernel socket users that may recurse during reclaim have benn
converted to sk_use_task_frag = false, we can have sk_page_frag() simply
check that value.

fb87bd4751 net: Introduce sk_use_task_frag in struct sock.
Sockets that can be used while recursing into memory reclaim, like
those used by network block devices and file systems, mustn't use
current->task_frag: if the current process is already using it, then
the inner memory reclaim call would corrupt the task_frag structure.

To avoid this, sk_page_frag() uses ->sk_allocation to detect sockets
that mustn't use current->task_frag, assuming that those used during
memory reclaim had their allocation constraints reflected in
->sk_allocation.

This unfortunately doesn't cover all cases: in an attempt to remove all
usage of GFP_NOFS and GFP_NOIO, sunrpc stopped setting these flags in
->sk_allocation, and used memalloc_nofs critical sections instead.
This breaks the sk_page_frag() heuristic since the allocation
constraints are now stored in current->flags, which sk_page_frag()
can't read without risking triggering a cache miss and slowing down
TCP's fast path.

This patch creates a new field in struct sock, named sk_use_task_frag,
which sockets with memory reclaim constraints can set to false if they
can't safely use current->task_frag. In such cases, sk_page_frag() now
always returns the socket's page_frag (->sk_frag). The first user is
sunrpc, which needs to avoid using current->task_frag but can keep
->sk_allocation set to GFP_KERNEL otherwise.

Eventually, it might be possible to simplify sk_page_frag() by only
testing ->sk_use_task_frag and avoid relying on the ->sk_allocation
heuristic entirely (assuming other sockets will set ->sk_use_task_frag
according to their constraints in the future).

The new ->sk_use_task_frag field is placed in a hole in struct sock and
belongs to a cache line shared with ->sk_shutdown. Therefore it should
be hot and shouldn't have negative performance impacts on TCP's fast
path (sk_shutdown is tested just before the while() loop in
tcp_sendmsg_locked()).
