6ccdc91d6a x86: mm: remove architecture-specific 'access_ok()' define 
There's already a generic definition of 'access_ok()' in the
asm-generic/access_ok.h header file, and the only difference bwteen that
and the x86-specific one is the added check for WARN_ON_IN_IRQ().

And it turns out that the reason for that check is long gone: it used to
use a "user_addr_max()" inline function that depended on the current
thread, and caused problems in non-thread contexts.

For details, see commits 7c4788950b ("x86/uaccess, sched/preempt:
Verify access_ok() context") and in particular commit ae31fe51a3
("perf/x86: Restore TASK_SIZE check on frame pointer") about how and why
this came to be.

But that "current task" issue was removed in the big set_fs() removal by
Christoph Hellwig in commit 47058bb54b ("x86: remove address space
overrides using set_fs()").

So the reason for the test and the architecture-specific access_ok()
define no longer exists, and is actually harmful these days.  For
example, it led various 'copy_from_user_nmi()' games (eg using
__range_not_ok() instead, and then later converted to __access_ok() when
that became ok).

And that in turn meant that LAM was broken for the frame following
before this series, because __access_ok() used to not do the address
untagging.

Accessing user state still needs care in many contexts, but access_ok()
is not the place for this test.

6014bc2756 x86-64: make access_ok() independent of LAM 
The linear address masking (LAM) code made access_ok() more complicated,
in that it now needs to untag the address in order to verify the access
range.  See commit 74c228d20a ("x86/uaccess: Provide untagged_addr()
and remove tags before address check").

We were able to avoid that overhead in the get_user/put_user code paths
by simply using the sign bit for the address check, and depending on the
GP fault if the address was non-canonical, which made it all independent
of LAM.

And we can do the same thing for access_ok(): simply check that the user
pointer range has the high bit clear.  No need to bother with any
address bit masking.

In fact, we can go a bit further, and just check the starting address
for known small accesses ranges: any accesses that overflow will still
be in the non-canonical area and will still GP fault.

To still make syzkaller catch any potentially unchecked user addresses,
we'll continue to warn about GP faults that are caused by accesses in
the non-canonical range.  But we'll limit that to purely "high bit set
and past the one-page 'slop' area".

We could probably just do that "check only starting address" for any
arbitrary range size: realistically all kernel accesses to user space
will be done starting at the low address.  But let's leave that kind of
optimization for later.  As it is, this already allows us to generate
simpler code and not worry about any tag bits in the address.

The one thing to look out for is the GUP address check: instead of
actually copying data in the virtual address range (and thus bad
addresses being caught by the GP fault), GUP will look up the page
tables manually.  As a result, the page table limits need to be checked,
and that was previously implicitly done by the access_ok().

With the relaxed access_ok() check, we need to just do an explicit check
for TASK_SIZE_MAX in the GUP code instead.  The GUP code already needs
to do the tag bit unmasking anyway, so there this is all very
straightforward, and there are no LAM issues.

348551ddaf Pin control bulk changes for the v6.4 kernel: 
Core changes:
 
 - Make a lot of pin controllers with GPIO and irqchips immutable,
   i.e. not living structs, but const structs. This is driving a
   changed initiated by the irqchip maintainers.
 
 New drivers:
 
 - New driver for the NXP S32 SoC pin controller
 
 - As part of a thorough cleanup and restructuring of the
   Ralink/Mediatek drivers, the Ralink MIPS pin control drivers
   were folded into the Mediatek directory and the family is
   renamed "mtmips". The Ralink chips live on as Mediatek MIPS
   family where new variants can be added. As part of this work
   also the device tree bindings were reworked.
 
 - New subdriver for the Qualcomm SM7150 SoC.
 
 - New subdriver for the Qualcomm IPQ9574 SoC.
 
 - New driver for the nVidia BlueField-3 SoC.
 
 - Support for the Qualcomm PMM8654AU mixed signal circuit GPIO.
 
 - Support for the Qualcomm PMI632 mixed signal circuit GPIO.
 
 Improvements:
 
 - Add some missing pins and generic cleanups on the Renesas
   r8a779g0 and r8a779g0 pin controllers. Generic Renesas
   extension for power source selection on several SoCs.
 
 - Misc cleanups for the Atmel AT91 and AT91-PIO4 pin
   controllers
 
 - Make the GPIO mode work on the Qualcomm SM8550-lpass-lpi
   driver.
 
 - Several device tree binding cleanups as the binding
   YAML syntax is solidifying.

9ea4eff4b6 afs: Avoid endless loop if file is larger than expected 
afs_read_dir fetches an amount of data that's based on what the inode
size is thought to be.  If the file on the server is larger than what
was fetched, the code rechecks i_size and retries.  If the local i_size
was not properly updated, this can lead to an endless loop of fetching
i_size from the server and noticing each time that the size is larger on
the server.

If it is known that the remote size is larger than i_size, bump up the
fetch size to that size.

45f66fa03b afs: Fix getattr to report server i_size on dirs, not local size 
Fix afs_getattr() to report the server's idea of the file size of a
directory rather than the local size.  The local size may differ as we edit
the local copy to avoid having to redownload it and we may end up with a
differently structured blob of a different size.

However, if the directory is discarded from the pagecache we then download
it again and the user may see the directory file size apparently change.

If the data version returned from the server is larger than expected,
the local data is invalidated, but we may still want to note the remote
file size.

Since we're setting change_size, we have to also set data_changed
for the i_size to get updated.

c8c655c34e s390: 
* More phys_to_virt conversions
 
 * Improvement of AP management for VSIE (nested virtualization)
 
 ARM64:
 
 * Numerous fixes for the pathological lock inversion issue that
   plagued KVM/arm64 since... forever.
 
 * New framework allowing SMCCC-compliant hypercalls to be forwarded
   to userspace, hopefully paving the way for some more features
   being moved to VMMs rather than be implemented in the kernel.
 
 * Large rework of the timer code to allow a VM-wide offset to be
   applied to both virtual and physical counters as well as a
   per-timer, per-vcpu offset that complements the global one.
   This last part allows the NV timer code to be implemented on
   top.
 
 * A small set of fixes to make sure that we don't change anything
   affecting the EL1&0 translation regime just after having having
   taken an exception to EL2 until we have executed a DSB. This
   ensures that speculative walks started in EL1&0 have completed.
 
 * The usual selftest fixes and improvements.
 
 KVM x86 changes for 6.4:
 
 * Optimize CR0.WP toggling by avoiding an MMU reload when TDP is enabled,
   and by giving the guest control of CR0.WP when EPT is enabled on VMX
   (VMX-only because SVM doesn't support per-bit controls)
 
 * Add CR0/CR4 helpers to query single bits, and clean up related code
   where KVM was interpreting kvm_read_cr4_bits()'s "unsigned long" return
   as a bool
 
 * Move AMD_PSFD to cpufeatures.h and purge KVM's definition
 
 * Avoid unnecessary writes+flushes when the guest is only adding new PTEs
 
 * Overhaul .sync_page() and .invlpg() to utilize .sync_page()'s optimizations
   when emulating invalidations
 
 * Clean up the range-based flushing APIs
 
 * Revamp the TDP MMU's reaping of Accessed/Dirty bits to clear a single
   A/D bit using a LOCK AND instead of XCHG, and skip all of the "handle
   changed SPTE" overhead associated with writing the entire entry
 
 * Track the number of "tail" entries in a pte_list_desc to avoid having
   to walk (potentially) all descriptors during insertion and deletion,
   which gets quite expensive if the guest is spamming fork()
 
 * Disallow virtualizing legacy LBRs if architectural LBRs are available,
   the two are mutually exclusive in hardware
 
 * Disallow writes to immutable feature MSRs (notably PERF_CAPABILITIES)
   after KVM_RUN, similar to CPUID features
 
 * Overhaul the vmx_pmu_caps selftest to better validate PERF_CAPABILITIES
 
 * Apply PMU filters to emulated events and add test coverage to the
   pmu_event_filter selftest
 
 x86 AMD:
 
 * Add support for virtual NMIs
 
 * Fixes for edge cases related to virtual interrupts
 
 x86 Intel:
 
 * Don't advertise XTILE_CFG in KVM_GET_SUPPORTED_CPUID if XTILE_DATA is
   not being reported due to userspace not opting in via prctl()
 
 * Fix a bug in emulation of ENCLS in compatibility mode
 
 * Allow emulation of NOP and PAUSE for L2
 
 * AMX selftests improvements
 
 * Misc cleanups
 
 MIPS:
 
 * Constify MIPS's internal callbacks (a leftover from the hardware enabling
   rework that landed in 6.3)
 
 Generic:
 
 * Drop unnecessary casts from "void *" throughout kvm_main.c
 
 * Tweak the layout of "struct kvm_mmu_memory_cache" to shrink the struct
   size by 8 bytes on 64-bit kernels by utilizing a padding hole

310897659c Rust changes for v6.4 
More additions to the Rust core. Importantly, this adds the pin-init
 API, which will be used by other abstractions, such as the
 synchronization ones added here too:
 
   - pin-init API: a solution for the safe pinned initialization problem.
     This allows to reduce the need for 'unsafe' code in the kernel when
     dealing with data structures that require a stable address. Commit
     90e53c5e70 ("rust: add pin-init API core") contains a nice
     introduction -- here is an example of how it looks like:
 
         #[pin_data]
         struct Example {
             #[pin]
             value: Mutex<u32>,
 
             #[pin]
             value_changed: CondVar,
         }
 
         impl Example {
             fn new() -> impl PinInit<Self> {
                 pin_init!(Self {
                     value <- new_mutex!(0),
                     value_changed <- new_condvar!(),
                 })
             }
         }
 
         // In a `Box`.
         let b = Box::pin_init(Example::new())?;
 
         // In the stack.
         stack_pin_init!(let s = Example::new());
 
   - 'sync' module: new types 'LockClassKey' ('struct lock_class_key'),
     'Lock', 'Guard', 'Mutex' ('struct mutex'), 'SpinLock'
     ('spinlock_t'), 'LockedBy' and 'CondVar' (uses 'wait_queue_head_t'),
     plus macros such as 'static_lock_class!' and 'new_spinlock!'.
 
     In particular, 'Lock' and 'Guard' are generic implementations that
     contain code that is common to all locks. Then, different backends
     (the new 'Backend' trait) are implemented and used to define types
     like 'Mutex':
 
         type Mutex<T> = Lock<T, MutexBackend>;
 
     In addition, new methods 'assume_init()', 'init_with()' and
     'pin_init_with()' for 'UniqueArc<MaybeUninit<T>>' and 'downcast()'
     for 'Arc<dyn Any + Send + Sync>'; as well as 'Debug' and 'Display'
     implementations for 'Arc' and 'UniqueArc'. Reduced stack usage of
     'UniqueArc::try_new_uninit()', too.
 
   - 'types' module: new trait 'AlwaysRefCounted' and new type 'ARef'
     (an owned reference to an always-reference-counted object, meant to
     be used in wrappers for C types that have their own ref counting
     functions).
 
     Moreover, new associated functions 'raw_get()' and 'ffi_init()'
     for 'Opaque'.
 
   - New 'task' module with a new type 'Task' ('struct task_struct'), and
     a new macro 'current!' to safely get a reference to the current one.
 
   - New 'ioctl' module with new '_IOC*' const functions (equivalent to
     the C macros).
 
   - New 'uapi' crate, intended to be accessible by drivers directly.
 
   - 'macros' crate: new 'quote!' macro (similar to the one provided in
     userspace by the 'quote' crate); and the 'module!' macro now allows
     specifying multiple module aliases.
 
   - 'error' module: new associated functions for the 'Error' type,
     such as 'from_errno()' and new functions such as 'to_result()'.
 
   - 'alloc' crate: more fallible 'Vec' methods: 'try_resize` and
     'try_extend_from_slice' and the infrastructure (imported from
     the Rust standard library) they need.

e81507acdc Nothing looks out of the ordinary in this batch of clk driver updates. There 
are a couple patches to the core clk framework, but they're all basically
 cleanups or debugging aids. The driver updates and new additions are dominated
 in the diffstat by Qualcomm and MediaTek drivers. Qualcomm gained a handful of
 new drivers for various SoCs, and MediaTek gained a bunch of drivers for
 MT8188. The MediaTek drivers are being modernized as well, so there are
 updates all over that vendor's clk drivers. There's also a couple other new clk
 drivers in here, for example the Starfive JH7110 SoC support is added.
 
 Outside of the two major SoC vendors though, we have the usual collection of
 non-critical fixes and cleanups to various clk drivers. It's good to see that
 we're getting more cleanups and modernization patches. Maybe one day we'll be
 able to properly split clk providers from clk consumers.
 
 Core:
  - Print an informational message before disabling unused clks
 
 New Drivers:
  - BCM63268 timer clock and reset controller
  - Frequency Hopping (FHCTL) on MediaTek MT6795, MT8173, MT8192 and
    MT8195 SoCs
  - Mediatek MT8188 SoC clk drivers
  - Clock driver for Sunplus SP7021 SoC
  - Clk driver support for Loongson-2 SoCs
  - Clock driver for Skyworks Si521xx I2C PCIe clock generators
  - Initial Starfive JH7110 clk/reset support
  - Global clock controller drivers for Qualcomm SM7150, IPQ9574, MSM8917 and IPQ5332 SoCs
  - GPU clock controller drivers for SM6115, SM6125, SM6375 and SA8775P SoCs
 
 Updates:
  - Shrink size of clk_fractional_divider a little
  - Convert various clk drivers to devm_of_clk_add_hw_provider()
  - Convert platform clk drivers to remove_new()
  - Converted most Mediatek clock drivers to struct platform_driver
  - MediaTek clock drivers can be built as modules
  - Reimplement Loongson-1 clk driver with DT support
  - Migrate socfpga clk driver to of_clk_add_hw_provider()
  - Support for i3c clks on Aspeed ast2600 SoCs
  - Add clock generic devm_clk_hw_register_gate_parent_data
  - Add audiomix block control for i.MX8MP
  - Add support for determine_rate to i.MX composite-8m
  - Let the LCDIF Pixel clock of i.MX8MM and i.MX8MN set parent rate
  - Provide clock name in error message for clk-gpr-mux on get parent failure
  - Drop duplicate imx_clk_mux_flags macro
  - Register the i.MX8MP Media Disp2 Pix clock as bus clock
  - Add Media LDB root clock to i.MX8MP
  - Make i.MX8MP nand_usdhc_bus clock as non-critical
  - Fix the rate table for i.MX fracn-gppll
  - Disable HW control for the fracn-gppll in order to be controlled by
    register write
  - Add support for interger PLL in fracn-gppll
  - Add mcore_booted module parameter to i.MX93 provider
  - Add NIC, A55 and ARM PLL clocks to i.MX93
  - Fix i.MX8ULP XBAR_DIVBUS and AD_SLOW clock parents
  - Use "divider closest" clock type for PLL4_PFD dividers on i.MX8ULP to
    get more accurate clock rates
  - Mark the MU0_Bi and TPM5 clocks on i.MX8ULP as critical
  - Update some of the i.MX critical clocks flags to allow glitchless

Pull clk updates from Stephen Boyd:
 "Nothing looks out of the ordinary in this batch of clk driver updates.

  There are a couple patches to the core clk framework, but they're all
  basically cleanups or debugging aids. The driver updates and new
  additions are dominated in the diffstat by Qualcomm and MediaTek
  drivers. Qualcomm gained a handful of new drivers for various SoCs,
  and MediaTek gained a bunch of drivers for MT8188. The MediaTek
  drivers are being modernized as well, so there are updates all over
  that vendor's clk drivers. There's also a couple other new clk drivers
  in here, for example the Starfive JH7110 SoC support is added.

  Outside of the two major SoC vendors though, we have the usual
  collection of non-critical fixes and cleanups to various clk drivers.
  It's good to see that we're getting more cleanups and modernization
  patches. Maybe one day we'll be able to properly split clk providers
  from clk consumers.

  Core:
   - Print an informational message before disabling unused clks

  New Drivers:
   - BCM63268 timer clock and reset controller
   - Frequency Hopping (FHCTL) on MediaTek MT6795, MT8173, MT8192 and
     MT8195 SoCs
   - Mediatek MT8188 SoC clk drivers
   - Clock driver for Sunplus SP7021 SoC
   - Clk driver support for Loongson-2 SoCs
   - Clock driver for Skyworks Si521xx I2C PCIe clock generators
   - Initial Starfive JH7110 clk/reset support
   - Global clock controller drivers for Qualcomm SM7150, IPQ9574,
     MSM8917 and IPQ5332 SoCs
   - GPU clock controller drivers for SM6115, SM6125, SM6375 and SA8775P
     SoCs

  Updates:
   - Shrink size of clk_fractional_divider a little
   - Convert various clk drivers to devm_of_clk_add_hw_provider()
   - Convert platform clk drivers to remove_new()
   - Converted most Mediatek clock drivers to struct platform_driver
   - MediaTek clock drivers can be built as modules
   - Reimplement Loongson-1 clk driver with DT support
   - Migrate socfpga clk driver to of_clk_add_hw_provider()
   - Support for i3c clks on Aspeed ast2600 SoCs
   - Add clock generic devm_clk_hw_register_gate_parent_data
   - Add audiomix block control for i.MX8MP
   - Add support for determine_rate to i.MX composite-8m
   - Let the LCDIF Pixel clock of i.MX8MM and i.MX8MN set parent rate
   - Provide clock name in error message for clk-gpr-mux on get parent
     failure
   - Drop duplicate imx_clk_mux_flags macro
   - Register the i.MX8MP Media Disp2 Pix clock as bus clock
   - Add Media LDB root clock to i.MX8MP
   - Make i.MX8MP nand_usdhc_bus clock as non-critical
   - Fix the rate table for i.MX fracn-gppll
   - Disable HW control for the fracn-gppll in order to be controlled by
     register write
   - Add support for interger PLL in fracn-gppll
   - Add mcore_booted module parameter to i.MX93 provider
   - Add NIC, A55 and ARM PLL clocks to i.MX93
   - Fix i.MX8ULP XBAR_DIVBUS and AD_SLOW clock parents
   - Use "divider closest" clock type for PLL4_PFD dividers on i.MX8ULP
     to get more accurate clock rates
   - Mark the MU0_Bi and TPM5 clocks on i.MX8ULP as critical
   - Update some of the i.MX critical clocks flags to allow glitchless
     on-the-fly rate change.
   - Add I2C5 clock on Renesas R-Car V3H

4e1c80ae5c NFSD 6.4 Release Notes 
The big ticket item for this release is support for RPC-with-TLS
 [RFC 9289] has been added to the Linux NFS server. The goal is to
 provide a simple-to-deploy, low-overhead in-transit confidentiality
 and peer authentication mechanism. It can supplement NFS Kerberos
 and it can protect the use of legacy non-cryptographic user
 authentication flavors such as AUTH_SYS. The TLS Record protocol is
 handled entirely by kTLS, meaning it can use either software
 encryption or offload encryption to smart NICs.
 
 Work continues on improving NFSD's open file cache. Among the many
 clean-ups in that area is a patch to convert the rhashtable to use
 the list-hashing version of that data structure.

 "New code:

   - add missed "nocase" in ntfs_show_options

   - extend information on failures/errors

   - small optimizations

  Fixes:

   - some logic errors

   - some dead code was removed

   - code is refactored and reformatted according to the new version of
     clang-format

  Code removal:

   - 'noacsrules' option.

     Currently, this option does not work properly, and its use leads to
     unstable results. If we figure out how to implement it without
     errors, we will add it later
