8536a5ef88 ARM: 9169/1: entry: fix Thumb2 bug in iWMMXt exception handling
The Thumb2 version of the FP exception handling entry code treats the
register holding the CP number (R8) differently, resulting in the iWMMXT
CP number check to be incorrect.

Fix this by unifying the ARM and Thumb2 code paths, and switch the
order of the additions of the TI_USED_CP offset and the shifted CP
index.

4bc5e64e6c efi: Move efifb_setup_from_dmi() prototype from arch headers
Commit 8633ef82f1 ("drivers/firmware: consolidate EFI framebuffer setup
for all arches") made the Generic System Framebuffers (sysfb) driver able
to be built on non-x86 architectures.

But it left the efifb_setup_from_dmi() function prototype declaration in
the architecture specific headers. This could lead to the following
compiler warning as reported by the kernel test robot:

   drivers/firmware/efi/sysfb_efi.c:70:6: warning: no previous prototype for function 'efifb_setup_from_dmi' [-Wmissing-prototypes]
   void efifb_setup_from_dmi(struct screen_info *si, const char *opt)

There are no devicetree users in mainline that use the old name,

Pull folio fixes from Matthew Wilcox:
 "In the course of preparing the folio changes for iomap for next merge
  window, we discovered some problems that would be nice to address now:

   - Renaming multi-page folios to large folios.

     mapping_multi_page_folio_support() is just a little too long, so we
     settled on mapping_large_folio_support(). That meant renaming, eg
     folio_test_multi() to folio_test_large().

     Rename AS_THP_SUPPORT to match

   - I hadn't included folio wrappers for zero_user_segments(), etc.
     Also, multi-page^W^W large folio support is now independent of
     CONFIG_TRANSPARENT_HUGEPAGE, so machines with HIGHMEM always need
     to fall back to the out-of-line zero_user_segments().

     Remove FS_THP_SUPPORT to match

   - The build bots finally got round to telling me that I missed a
     couple of architectures when adding flush_dcache_folio(). Christoph
     suggested that we just add linux/cacheflush.h and not rely on
     asm-generic/cacheflush.h"

e691f9282a ARM: dts: ls1021a-tsn: update RGMII delays for sja1105 switch
In the new behavior, the sja1105 driver expects there to be explicit
RGMII delays present on the fixed-link ports, otherwise it will complain
that it falls back to legacy behavior, which is to apply RGMII delays
incorrectly derived from the phy-mode string.

In this case, the legacy behavior of the driver is to not apply delays
in any direction (mostly because the SJA1105T can't do that, so this
board uses PCB traces). To preserve that but also silence the driver,
use explicit delays of 0 ns. The delay information from the phy-mode is
ignored by new kernels (it's still RGMII as long as it's "rgmii*"
something), and the explicit {rx,tx}-internal-delay-ps properties are
ignored by old kernels, so the change works both ways.

825c43f50e kmap_local: don't assume kmap PTEs are linear arrays in memory
The kmap_local conversion broke the ARM architecture, because the new
code assumes that all PTEs used for creating kmaps form a linear array
in memory, and uses array indexing to look up the kmap PTE belonging to
a certain kmap index.

On ARM, this cannot work, not only because the PTE pages may be
non-adjacent in memory, but also because ARM/!LPAE interleaves hardware
entries and extended entries (carrying software-only bits) in a way that
is not compatible with array indexing.

Fortunately, this only seems to affect configurations with more than 8
CPUs, due to the way the per-CPU kmap slots are organized in memory.

Work around this by permitting an architecture to set a Kconfig symbol
that signifies that the kmap PTEs do not form a lineary array in memory,
and so the only way to locate the appropriate one is to walk the page
tables.

522a0032af Add linux/cacheflush.h
Many architectures do not include asm-generic/cacheflush.h, so turn
the includes on their head and add linux/cacheflush.h which includes
asm/cacheflush.h.

Move the flush_dcache_folio() declaration from asm-generic/cacheflush.h
to linux/cacheflush.h and change linux/highmem.h to include
linux/cacheflush.h instead of asm/cacheflush.h so that all necessary
places will see flush_dcache_folio().

More functions should have their default implementations moved in the
future, but those are for follow-on patches.  This fixes csky, sparc and
sparc64 which were missed in the commit which added flush_dcache_folio().

ebf7f6f0a6 bpf: Change value of MAX_TAIL_CALL_CNT from 32 to 33
In the current code, the actual max tail call count is 33 which is greater
than MAX_TAIL_CALL_CNT (defined as 32). The actual limit is not consistent
with the meaning of MAX_TAIL_CALL_CNT and thus confusing at first glance.
We can see the historical evolution from commit 04fd61ab36 ("bpf: allow
bpf programs to tail-call other bpf programs") and commit f9dabe016b
("bpf: Undo off-by-one in interpreter tail call count limit"). In order
to avoid changing existing behavior, the actual limit is 33 now, this is
reasonable.

After commit 874be05f52 ("bpf, tests: Add tail call test suite"), we can
see there exists failed testcase.

On all archs when CONFIG_BPF_JIT_ALWAYS_ON is not set:
 # echo 0 > /proc/sys/net/core/bpf_jit_enable
 # modprobe test_bpf
 # dmesg | grep -w FAIL
 Tail call error path, max count reached jited:0 ret 34 != 33 FAIL

On some archs:
 # echo 1 > /proc/sys/net/core/bpf_jit_enable
 # modprobe test_bpf
 # dmesg | grep -w FAIL
 Tail call error path, max count reached jited:1 ret 34 != 33 FAIL

Although the above failed testcase has been fixed in commit 18935a72eb
("bpf/tests: Fix error in tail call limit tests"), it would still be good
to change the value of MAX_TAIL_CALL_CNT from 32 to 33 to make the code
more readable.

The 32-bit x86 JIT was using a limit of 32, just fix the wrong comments and
limit to 33 tail calls as the constant MAX_TAIL_CALL_CNT updated. For the
mips64 JIT, use "ori" instead of "addiu" as suggested by Johan Almbladh.
For the riscv JIT, use RV_REG_TCC directly to save one register move as
suggested by Björn Töpel. For the other implementations, no function changes,
it does not change the current limit 33, the new value of MAX_TAIL_CALL_CNT
can reflect the actual max tail call count, the related tail call testcases
in test_bpf module and selftests can work well for the interpreter and the
JIT.

Here are the test results on x86_64:

 # uname -m
 x86_64
 # echo 0 > /proc/sys/net/core/bpf_jit_enable
 # modprobe test_bpf test_suite=test_tail_calls
 # dmesg | tail -1
 test_bpf: test_tail_calls: Summary: 8 PASSED, 0 FAILED, [0/8 JIT'ed]
 # rmmod test_bpf
 # echo 1 > /proc/sys/net/core/bpf_jit_enable
 # modprobe test_bpf test_suite=test_tail_calls
 # dmesg | tail -1
 test_bpf: test_tail_calls: Summary: 8 PASSED, 0 FAILED, [8/8 JIT'ed]
 # rmmod test_bpf
 # ./test_progs -t tailcalls
 #142 tailcalls:OK

PCIE_INTR2 second level interrupt controller and one for its MSI second

418ace9992 ARM: 9156/1: drop cc-option fallbacks for architecture selection
Naresh and Antonio ran into a build failure with latest Debian
armhf compilers, with lots of output like

 tmp/ccY3nOAs.s:2215: Error: selected processor does not support `cpsid i' in ARM mode

As it turns out, $(cc-option) fails early here when the FPU is not
selected before CPU architecture is selected, as the compiler
option check runs before enabling -msoft-float, which causes
a problem when testing a target architecture level without an FPU:

cc1: error: '-mfloat-abi=hard': selected architecture lacks an FPU

Passing e.g. -march=armv6k+fp in place of -march=armv6k would avoid this
issue, but the fallback logic is already broken because all supported
compilers (gcc-5 and higher) are much more recent than these options,
and building with -march=armv5t as a fallback no longer works.

The best way forward that I see is to just remove all the checks, which
also has the nice side-effect of slightly improving the startup time for
'make'.

The -mtune=marvell-f option was apparently never supported by any mainline
compiler, and the custom Codesourcery gcc build that did support is
now too old to build kernels, so just use -mtune=xscale unconditionally
for those.

This should be safe to apply on all stable kernels, and will be required
in order to keep building them with gcc-11 and higher.

c6975d7cab arm64: Track no early_pgtable_alloc() for kmemleak
After switched page size from 64KB to 4KB on several arm64 servers here,
kmemleak starts to run out of early memory pool due to a huge number of
those early_pgtable_alloc() calls:

  kmemleak_alloc_phys()
  memblock_alloc_range_nid()
  memblock_phys_alloc_range()
  early_pgtable_alloc()
  init_pmd()
  alloc_init_pud()
  __create_pgd_mapping()
  __map_memblock()
  paging_init()
  setup_arch()
  start_kernel()

Increased the default value of DEBUG_KMEMLEAK_MEM_POOL_SIZE by 4 times
won't be enough for a server with 200GB+ memory. There isn't much
interesting to check memory leaks for those early page tables and those
early memory mappings should not reference to other memory. Hence, no
kmemleak false positives, and we can safely skip tracking those early
allocations from kmemleak like we did in the commit fed84c7852
("mm/memblock.c: skip kmemleak for kasan_init()") without needing to
introduce complications to automatically scale the value depends on the
runtime memory size etc. After the patch, the default value of
DEBUG_KMEMLEAK_MEM_POOL_SIZE becomes sufficient again.

Pull ARM SoC driver updates from Arnd Bergmann:
 "These are all the driver updates for SoC specific drivers. There are a
  couple of subsystems with individual maintainers picking up their
  patches here:

   - The reset controller subsystem add support for a few new SoC
     variants to existing drivers, along with other minor improvements

   - The OP-TEE subsystem gets a driver for the ARM FF-A transport

   - The memory controller subsystem has improvements for Tegra,
     Mediatek, Renesas, Freescale and Broadcom specific drivers.

   - The tegra cpuidle driver changes get merged through this tree this
     time. There are only minor changes, but they depend on other tegra
     driver updates here.

   - The ep93xx platform finally moves to using the drivers/clk/
     subsystem, moving the code out of arch/arm in the process. This
     depends on a small sound driver change that is included here as
     well.

   - There are some minor updates for Qualcomm and Tegra specific
     firmware drivers.

  The other driver updates are mainly for drivers/soc, which contains a
  mixture of vendor specific drivers that don't really fit elsewhere:

   - Mediatek drivers gain more support for MT8192, with new support for
     hw-mutex and mmsys routing, plus support for reset lines in the
     mmsys driver.

   - Qualcomm gains a new "sleep stats" driver, and support for the
     "Generic Packet Router" in the APR driver.

   - There is a new user interface for routing the UARTS on ASpeed BMCs,
     something that apparently nobody else has needed so far.

   - More drivers can now be built as loadable modules, in particular
     for Broadcom and Samsung platforms.

   - Lots of improvements to the TI sysc driver for better
     suspend/resume support"

  Finally, there are lots of minor cleanups and new device IDs for
  amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx,
  layerscape, allwinner, broadcom, and omap"

Pull ARM SoC DT updates from Arnd Bergmann:
 "This is a rather large update for the ARM devicetree files, after a
  few quieter releases, with 775 total commits and 47 branches pulled
  into this one.

  There are 5 new SoC types plus some minor variations, and a total of
  60 new machines, so I'm limiting the summary to the main noteworthy
  items:

   - Apple M1 gain support for PCI and pinctrl, getting a bit closer to
     a usable system out of the box.

   - Qualcomm gains support for Snapdragon 690 (aka SM6350) as well as
     SM7225, 11 new smartphones, and three additional Chromebooks, and
     improvements all over the place.

   - Samsung gains support for ExynosAutov9, an automotive version of
     their smartphone SoC, but otherwise no major changes.

   - Microchip adds the SAMA5D29 SoC in the SAMA5 family, and a number
     of improvements for the recently added SAMA7 family. The LAN966 SoC
     that was added in the platform code does not have dts files yet.
     Two board files are added for the older at91sam9g20 SoC

   - Aspeed supports two additional server boards using their AST2600 as
     BMC, and improves support for qemu models

   - Rockchip RK3566/RK3688 gets added, along with six new development
     boards using RK3328/RK3399/RK3566, and one Chromebook tablet.

   - Two NAS boxes are added using the ARMv4 based Gemini platform

   - One new board is added to the Intel Arria SoC FPGA family

   - Marvell adds one network switch based on Armada 381 and the new
     MOCHAbin 7040 development board

   - NXP adds support for the S32G2 automotive SoC, two imx6 based ebook
     readers, and three additional development boards, which is notably
     less than their usual additions, but they also gain improvements to
     their many existing boards

   - STmicroelectronics adds their stm32mp13 SoC family along with a
     reference board

   - Renesas adds new versions of their R-Car Gen3 SoCs and many updates
     for their older generations

   - Broadcom adds support for a number of Cisco Meraki wireless
     controllers, along with two new boards and other updates for
     BCM53xx/BCM47xx networking SoCs and the Raspberry Pi boards

   - Mediatek improves support for the MT81xx SoCs used in Chromebooks
     as well as the MT76xx networking SoCs

   - NVIDIA adds a number of cleanups and additional support for more
     hardware on the already supported machines

   - TI K3 adds support for three new boards along with cleanups

   - Toshiba adds one board for the Visconti family

   - Xilinx adds five new ZynqMP based machines

   - Amlogic support is added for the Radxa Zero and two Jethub home
     automation controllers, along with changes to other machines

   - Rob Herring continues his work on fixing dtc warnings all over the
     tree.

   - Minor updates for TI OMAP, Mstar, Allwinner/sunxi, Hisilicon,
     Ux500, Unisoc"
