787af64d05 mm: page_alloc: validate buddy before check its migratetype.
Whenever a buddy page is found, page_is_buddy() should be called to
check its validity.  Add the missing check during pageblock merge check.

57c06b6e1e Modules updates for v5.18-rc1
There is only one patch which qualifies for modules for v5.18-rc1 and its
 a small fix from Dan Carpenter for lib/test_kmod module. The rest of the
 changes are too major and landed in modules-testing too late for inclusion.
 The good news is that most of the major changes for v5.19 is going to be
 tested very early through linux-next.
 
 This simple fix is all we have for modules for v5.18-rc1.

2c54e18406 remoteproc updates for v5.18
In the remoteproc core, it's now possible to mark the sysfs attributes
 read only on a per-instance basis, which is then used by the TI wkup M3
 driver. The rproc_shutdown() interface propagates errors to the caller
 and an array underflow is fixed in the debugfs interface. The
 rproc_da_to_va() API is moved to the public API to allow e.g. child
 rpmsg devices to acquire pointers to memory shared with the remote
 processor.
 
 The TI K3 R5F and DSP drivers gains support for attaching to instances
 already started by the bootloader, aka IPC-only mode.
 
 The Mediatek remoteproc driver gains support for the MT8186 SCP. The
 driver's probe function is reordered and moved to use the devres version
 of rproc_alloc() to save a few gotos. The driver's probe function is
 also transitioned to use dev_err_probe() to provide better debug
 support.
 
 Support for the Qualcomm SC7280 Wireless Subsystem (WPSS) is introduced.
 The Hexagon based remoteproc drivers gains support for voting for
 interconnect bandwidth during launch of the remote processor. The modem
 subsystem (MSS) driver gains support for probing the BAM-DMUX
 driver, which provides the network interface towards the modem on a set
 of older Qualcomm platforms.
 In addition a number a bug fixes are introduces in the Qualcomm drivers.
 
 Lastly Qualcomm ADSP DeviceTree binding is converted to YAML format, to
 allow validation of DeviceTree source files.

The major part of the rpmsg changes for v5.18 relates to improvements in
 the rpmsg char driver, which now allow automatically attaching to rpmsg
 channels as well as initiating new communication channels from the Linux
 side.
 
 The SMD driver is moved to arch_initcall with the purpose of registering
 root clocks earlier during boot. Also in the SMD driver, a workaround
 for the resource power management (RPM) channel is introduced to resolve
 an issue where both the RPM and Linux side waits for the other to close
 the communication established by the bootloader - this unblocks support
 for clocks and regulators on some older Qualcomm platforms.

9512433987 There's one large change in the core clk framework here. We change how
clk_set_rate_range() works so that the frequency is re-evaulated each time the
 rate is changed. Previously we wouldn't let clk providers see a rate that was
 different if it was still within the range, which could be bad for power if the
 clk could run slower when a range expands. Now the clk provider can decide to
 do something differently when the constraints change. This broke Nvidia's clk
 driver so we had to wait for the fix for that to bake a little more in -next.
 
 The rate range patch series also introduced a kunit suite for the clk framework
 that we're going to extend in the next release. It already made it easy to find
 corner cases in the rate range patches so I'm excited to see it cover more clk
 code and increase our confidence in core framework patches in the future. I
 also added a kunit test for the basic clk gate code and that work will continue
 to cover more basic clk types: muxes, dividers, etc.
 
 Beyond the core code we have the usual set of clk driver updates and additions.
 Qualcomm again dominates the diffstat here with lots more SoCs being supported
 and i.MX follows afer that with a similar number of SoCs gaining clk drivers.
 Beyond those large additions there's drivers being modernized to use
 clk_parent_data so we can move away from global string names for all the clks
 in an SoC. Finally there's lots of little fixes all over the clk drivers for
 typos, warnings, and missing clks that aren't critical and get batched up
 waiting for the next merge window to open. Nothing super big stands out in the
 driver pile. Full details are below.
 
 Core:
  - Make clk_set_rate_range() re-evaluate the limits each time
  - Introduce various clk_set_rate_range() tests
  - Add clk_drop_range() to drop a previously set range
 
 New Drivers:
  - i.MXRT1050 clock driver and bindings
  - i.MX8DXL clock driver and bindings
  - i.MX93 clock driver and bindings
  - NCO blocks on Apple SoCs
  - Audio clks on StarFive JH7100 RISC-V SoC
  - Add support for the new Renesas RZ/V2L SoC
  - Qualcomm SDX65 A7 PLL
  - Qualcomm SM6350 GPU clks
  - Qualcomm SM6125, SM6350, QCS2290 display clks
  - Qualcomm MSM8226 multimedia clks
 
 Updates:
  - Kunit tests for clk-gate implementation
  - Terminate arrays with sentinels and make that clearer
  - Cleanup SPDX tags
  - Fix typos in comments
  - Mark mux table as const in clk-mux
  - Make the all_lists array const
  - Convert Cirrus Logic CS2000P driver to regmap, yamlify DT binding and add
    support for dynamic mode
  - Clock configuration on Microchip PolarFire SoCs
  - Free allocations on probe error in Mediatek clk driver

    Renesas R-Car S4-8
  - Improve the clocks for the Rockchip rk3568 display outputs (parenting, pll-rates)
  - Use of_device_get_match_data() instead of open-coding on Rockchip rk3568
  - Reintroduce the expected fractional-divider behaviour that disappeared
    with the addition of CLK_FRAC_DIVIDER_POWER_OF_TWO_PS
  - Remove SYS PLL 1/2 clock gates for i.MX8M*
  - Remove AUDIO MCLK ROOT from i.MX7D
  - Add fracn gppll clock type used by i.MX93
  - Add new composite clock for i.MX93
  - Add missing media mipi phy ref clock for i.MX8MP
  - Fix off by one in imx_lpcg_parse_clks_from_dt()

d888c83fce fs: fix fd table size alignment properly
Jason Donenfeld reports that my commit 1c24a18639 ("fs: fd tables have
to be multiples of BITS_PER_LONG") doesn't work, and the reason is an
embarrassing brown-paper-bag bug.

Yes, we want to align the number of fds to BITS_PER_LONG, and yes, the
reason they might not be aligned is because the incoming 'max_fd'
argument might not be aligned.

But aligining the argument - while simple - will cause a "infinitely
big" maxfd (eg NR_OPEN_MAX) to just overflow to zero.  Which most
definitely isn't what we want either.

The obvious fix was always just to do the alignment last, but I had
moved it earlier just to make the patch smaller and the code look
simpler.  Duh.  It certainly made _me_ look simple.

Fixes: 1c24a18639 ("fs: fd tables have to be multiples of BITS_PER_LONG")

965181d7ef NFS client updates for Linux 5.18
Highlights include:
 
 Features:
 - Switch NFS to use readahead instead of the obsolete readpages.
 - Readdir fixes to improve cacheability of large directories when there
   are multiple readers and writers.
 - Readdir performance improvements when doing a seekdir() immediately
   after opening the directory (common when re-exporting NFS).
 - NFS swap improvements from Neil Brown.
 - Loosen up memory allocation to permit direct reclaim and write back
   in cases where there is no danger of deadlocking the writeback code or
   NFS swap.
 - Avoid sillyrename when the NFSv4 server claims to support the
   necessary features to recover the unlinked but open file after reboot.
 
 Bugfixes:
 - Patch from Olga to add a mount option to control NFSv4.1 session
   trunking discovery, and default it to being off.
 - Fix a lockup in nfs_do_recoalesce().
 - Two fixes for list iterator variables being used when pointing to the
   list head.
 - Fix a kernel memory scribble when reading from a non-socket transport
   in /sys/kernel/sunrpc.
 - Fix a race where reconnecting to a server could leave the TCP socket
   stuck forever in the connecting state.
 - Patch from Neil to fix a shutdown race which can leave the SUNRPC
   transport timer primed after we free the struct xprt itself.
 - Patch from Xin Xiong to fix reference count leaks in the NFSv4.2 copy
   offload.
 - Sunrpc patch from Olga to avoid resending a task on an offlined
   transport.
 
 Cleanups:
 - Patches from Dave Wysochanski to clean up the fscache code

1c24a18639 fs: fd tables have to be multiples of BITS_PER_LONG
This has always been the rule: fdtables have several bitmaps in them,
and as a result they have to be sized properly for bitmaps.  We walk
those bitmaps in chunks of 'unsigned long' in serveral cases, but even
when we don't, we use the regular kernel bitops that are defined to work
on arrays of 'unsigned long', not on some byte array.

Now, the distinction between arrays of bytes and 'unsigned long'
normally only really ends up being noticeable on big-endian systems, but
Fedor Pchelkin and Alexey Khoroshilov reported that copy_fd_bitmaps()
could be called with an argument that wasn't even a multiple of
BITS_PER_BYTE.  And then it fails to do the proper copy even on
little-endian machines.

The bug wasn't in copy_fd_bitmap(), but in sane_fdtable_size(), which
didn't actually sanitize the fdtable size sufficiently, and never made
sure it had the proper BITS_PER_LONG alignment.

That's partly because the alignment historically came not from having to
explicitly align things, but simply from previous fdtable sizes, and
from count_open_files(), which counts the file descriptors by walking
them one 'unsigned long' word at a time and thus naturally ends up doing
sizing in the proper 'chunks of unsigned long'.

But with the introduction of close_range(), we now have an external
source of "this is how many files we want to have", and so
sane_fdtable_size() needs to do a better job.

This also adds that explicit alignment to alloc_fdtable(), although
there it is mainly just for documentation at a source code level.  The
arithmetic we do there to pick a reasonable fdtable size already aligns
the result sufficiently.

In fact,clang notices that the added ALIGN() in that function doesn't
actually do anything, and does not generate any extra code for it.

It turns out that gcc ends up confusing itself by combining a previous
constant-sized shift operation with the variable-sized shift operations
in roundup_pow_of_two().  And probably due to that doesn't notice that
the ALIGN() is a no-op.  But that's a (tiny) gcc misfeature that doesn't
matter.  Having the explicit alignment makes sense, and would actually
matter on a 128-bit architecture if we ever go there.

This also adds big comments above both functions about how fdtable sizes
have to have that BITS_PER_LONG alignment.

a9fe7fa7d8 parisc: Fix patch code locking and flushing
This change fixes the following:

1) The flags variable is not initialized. Always use raw_spin_lock_irqsave
and raw_spin_unlock_irqrestore to serialize patching.

2) flush_kernel_vmap_range is primarily intended for DMA flushes. Since
__patch_text_multiple is often called with interrupts disabled, it is
better to directly call flush_kernel_dcache_range_asm and
flush_kernel_icache_range_asm. This avoids an extra call.

3) The final call to flush_icache_range is unnecessary.

37fcacb50b phy: PHY_FSL_LYNX_28G should depend on ARCH_LAYERSCAPE
Freescale Layerscape Lynx 28G SerDes PHYs are only present on
Freescale/NXP Layerscape SoCs.

Move PHY_FSL_LYNX_28G outside the block for ARCH_MXC, as the latter
is meant for i.MX8 SoCs, which is a different family than Layerscape.
Add a dependency on ARCH_LAYERSCAPE, to prevent asking the user about
this driver when configuring a kernel without Layerscape SoC support.

22a41e9a50 dt-bindings: Fix missing '/schemas' in $ref paths
Absolute paths in $ref should always begin with '/schemas'. The tools
mostly work with it omitted, but for correctness the path should be
everything except the hostname as that is taken from the schema's $id
value. This scheme is defined in the json-schema spec.
