xfs: kconfig and feature changes for 2025 LTS [6.18 v2 2/2]

Ahead of the 2025 LTS kernel, disable by default the two features that
we promised to turn off in September 2025: V4 filesystems, and the
long-broken ASCII case insensitive directories.

Since online fsck has not had any major issues in the 16 months since it
was merged upstream, let's also turn that on by default.

With a bit of luck, this should all go splendidly.

xfs: improve online repair reap calculations [6.18 v2 1/2]

A few months ago, the multi-fsblock untorn writes patchset added a bunch
of log intent item helper functions to estimate the number of intent
items that could be added to a particular transaction.  Those helpers
enabled us to compute a safe upper bound on the number of blocks that
could be written in an untorn fashion with filesystem-provided out of
place writes.

Currently, the online fsck code employs static limits on the number of
intent items that it's willing to accrue to a single transaction when
it's trying to reap what it thinks are the old blocks from a corrupt
structure.  There have been no problems reported with this approach
after years of testing, but static limits are scary and gross because
overestimating the intent item limit could result in transaction
overflows and dead filesystems; and underestimating causes unnecessary
overhead.

This series uses the new log intent item size helpers to estimate the
limits dynamically based on worst-case per-block repair work vs. the
size of the scrub transaction.  After several months of testing this,
there don't seem to be any problems here either.

v2: rearrange patches, add review tags

This has been running on the djcloud for months with no problems.  Enjoy!

d5b157e088 xfs: remove static reap limits from repair.h
Delete XREAP_MAX_BINVAL and XREAP_MAX_DEFER_CHAIN because the reap code
now calculates those limits dynamically, so they're no longer needed.

Move the third limit (XREP_MAX_ITRUNCATE_EFIS) to the one file that uses
it.  Note that the btree rebuilding code should reserve exactly the
number of blocks needed to rebuild a btree, so it is rare that the newbt
code will need to add any EFIs to the commit transaction.  That's why
that static limit remains.

e4c7eece76 xfs: compute file mapping reap limits dynamically
Reaping file fork mappings is a little different -- log recovery can
free the blocks for us, so we only try to process a single mapping at a
time.  Therefore, we only need to figure out the maximum number of
blocks that we can invalidate in a single transaction.

The rough calculation here is:

nr_extents = (logres - reservation used by any one step) /
		(space used per binval)

82e374405e xfs: prepare reaping code for dynamic limits
The online repair block reaping code employs static limits to decide if
it's time to roll the transaction or finish the deferred item chains to
avoid overflowing the scrub transaction's reservation.  However, the
use of static limits aren't great -- btree blocks are assumed to be
scattered around the AG and the buffers need to be invalidated, whereas
COW staging extents are usually contiguous and do not have buffers.  We
would like to configure the limits dynamically.

To get ready for this, reorganize struct xreap_state to store dynamic
limits, and add helpers to hide some of the details of how the limits
are enforced.  Also rename the "xreap roll" functions to include the
word "binval" because they only exist to decide when we should roll the
transaction to deal with buffer invalidations.

No functional changes intended here.

ceca927c86 arm64: mm: Fix CFI failure due to kpti_ng_pgd_alloc function signature
Seen during KPTI initialization:

  CFI failure at create_kpti_ng_temp_pgd+0x124/0xce8 (target: kpti_ng_pgd_alloc+0x0/0x14; expected type: 0xd61b88b6)

The call site is alloc_init_pud() at arch/arm64/mm/mmu.c:

  pud_phys = pgtable_alloc(TABLE_PUD);

alloc_init_pud() has the prototype:

  static void alloc_init_pud(p4d_t *p4dp, unsigned long addr, unsigned long end,
                             phys_addr_t phys, pgprot_t prot,
                             phys_addr_t (*pgtable_alloc)(enum pgtable_type),
                             int flags)

where the pgtable_alloc() prototype is declared.

The target (kpti_ng_pgd_alloc) is used in arch/arm64/kernel/cpufeature.c:

  create_kpti_ng_temp_pgd(kpti_ng_temp_pgd, __pa(alloc), KPTI_NG_TEMP_VA,
                          PAGE_SIZE, PAGE_KERNEL, kpti_ng_pgd_alloc, 0);

which is an alias for __create_pgd_mapping_locked() with prototype:

  extern __alias(__create_pgd_mapping_locked)
  void create_kpti_ng_temp_pgd(pgd_t *pgdir, phys_addr_t phys,
                               unsigned long virt,
                               phys_addr_t size, pgprot_t prot,
                               phys_addr_t (*pgtable_alloc)(enum pgtable_type),
                               int flags);

__create_pgd_mapping_locked() passes the function pointer down:

  __create_pgd_mapping_locked() -> alloc_init_p4d() -> alloc_init_pud()

But the target function (kpti_ng_pgd_alloc) has the wrong signature:

  static phys_addr_t __init kpti_ng_pgd_alloc(int shift);

The "int" should be "enum pgtable_type".

To make "enum pgtable_type" available to cpufeature.c, move
enum pgtable_type definition from arch/arm64/mm/mmu.c to
arch/arm64/include/asm/mmu.h.

Adjust kpti_ng_pgd_alloc to use "enum pgtable_type" instead of "int".
The function behavior remains identical (parameter is unused).

86a9b12506 hardening: Require clang 20.1.0 for __counted_by
After an innocuous change in -next that modified a structure that
contains __counted_by, clang-19 start crashing when building certain
files in drivers/gpu/drm/xe. When assertions are enabled, the more
descriptive failure is:

  clang: clang/lib/AST/RecordLayoutBuilder.cpp:3335: const ASTRecordLayout &clang::ASTContext::getASTRecordLayout(const RecordDecl *) const: Assertion `D && "Cannot get layout of forward declarations!"' failed.

According to a reverse bisect, a tangential change to the LLVM IR
generation phase of clang during the LLVM 20 development cycle [1]
resolves this problem. Bump the version of clang that enables
CONFIG_CC_HAS_COUNTED_BY to 20.1.0 to ensure that this issue cannot be
hit.

KVM/arm64 changes for 6.17, take #2

 - Correctly handle 'invariant' system registers for protected VMs

 - Improved handling of VNCR data aborts, including external aborts

 - Fixes for handling of FEAT_RAS for NV guests, providing a sane
   fault context during SEA injection and preventing the use of
   RASv1p1 fault injection hardware

 - Ensure that page table destruction when a VM is destroyed gives an
   opportunity to reschedule

 - Large fix to KVM's infrastructure for managing guest context loaded
   on the CPU, addressing issues where the output of AT emulation
   doesn't get reflected to the guest

 - Fix AT S12 emulation to actually perform stage-2 translation when
   necessary

 - Avoid attempting vLPI irqbypass when GICv4 has been explicitly
   disabled for a VM

 - Minor KVM + selftest fixes
