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.

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.

Currently, the .got section is placed within the output section .text.
However, when .got is non-empty, the SHF_WRITE flag is set for .text
when linked by lld. GNU ld recognizes .text as a special section and
ignores the SHF_WRITE flag. By renaming .text, we can also get the
SHF_WRITE flag.
The kernel has performed R_AARCH64_RELATIVE resolving very early, and can
then assume that .got is read-only. Let's move .got to the vmlinux_rodata
pseudo-segment.
As Ard Biesheuvel notes:
"This matters to consumers of the vmlinux ELF representation of the
kernel image, such as syzkaller, which disregards writable PT_LOAD
segments when resolving code symbols. The kernel itself does not care
about this distinction, but given that the GOT contains data and not
code, it does not require executable permissions, and therefore does
not belong in .text to begin with."

It seems BPF CO-RE reloc doesn't work well with the pattern that gets
the field-offset only. Use offsetof() to make it explicit so that
the compiler would generate the correct code.

The recent fix to ensure atomicity of lookup and allocation inadvertently
broke the pool refill mechanism.
Prior to that change debug_objects_activate() and debug_objecs_assert_init()
invoked debug_objecs_init() to set up the tracking object for statically
initialized objects. That's not longer the case and debug_objecs_init() is
now the only place which does pool refills.
Depending on the number of statically initialized objects this can be
enough to actually deplete the pool, which was observed by Ido via a
debugobjects OOM warning.
Restore the old behaviour by adding explicit refill opportunities to
debug_objects_activate() and debug_objecs_assert_init().

Automation complains:
warning: symbol '__pcpu_scope_misaligned_access_speed' was not declared. Should it be static?
cpufeature.c doesn't actually include the header of the same name, as it
had not previously used anything from it.
The per-cpu variable is declared there, so include it to silence the

The recent introduction of relocatable kernels prepared the move of
.rela.dyn to the init section, but actually forgot to do so, so do it
here.
Before this patch: "Freeing unused kernel image (initmem) memory: 2592K"
After this patch: "Freeing unused kernel image (initmem) memory: 6288K"
The difference corresponds to the size of the .rela.dyn section:
"[42] .rela.dyn RELA ffffffff8197e798 0127f798

The dt-binding was defined before the extraction of csr access and
fence.i into their own extensions, and thus the presence of the I
base extension implies Zicsr and Zifencei.
There's no harm in adding them obviously, but for backwards
compatibility with DTs that existed prior to that extraction, software
is unable to differentiate between "i" and "i_zicsr_zifencei" without
any further information.

* 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
Documentation:

The ftrace samples need per-architecture trampoline implementations to
save and restore argument registers around the calls to my_direct_func*
and to restore polluted registers (e.g: ra).

Select the HAVE_DYNAMIC_FTRACE_WITH_DIRECT_CALLS to provide the
register_ftrace_direct[_multi] interfaces allowing users to register
the customed trampoline (direct_caller) as the mcount for one or more
target functions. And modify_ftrace_direct[_multi] are also provided
for modifying direct_caller.
There are a few cases to distinguish:
- If a direct call ops is the only one tracing a function AND the direct
called trampoline is within the reach of a 'bl' instruction
-> the ftrace patchsite jumps to the trampoline
- Else
-> the ftrace patchsite jumps to the ftrace_regs_caller trampoline points
to ftrace_list_ops so it iterates over all registered ftrace ops,
including the direct call ops and calls its call_direct_funcs handler
which stores the direct called trampoline's address in the ftrace_regs
and the ftrace_regs_caller trampoline will return to that address
instead of returning to the traced function

In the module processing functions, the same logic can be reused by
