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"

In the code: larbostd = larb->larb_gen->ostd[larb->larbid],
if "larb->larb_gen->ostd" is null, the "larbostd" is the offset(e.g.
0x80 above), it's also a valid value, then accessing "larbostd[i]" in the
"for" loop will cause the KE above. To avoid this issue, initialize
"larbostd" to NULL when the SoC doesn't have ostd setting.

We must flush the TLB before releasing i_mmap_rwsem to avoid the

therefore be dropped before the TLB flush took place.

When __unmap_hugepage_range() calls to huge_pmd_unshare() succeed, a TLB
flush is missing.  This TLB flush must be performed before releasing the
i_mmap_rwsem, in order to prevent an unshared PMDs page from being
released and reused before the TLB flush took place.

Arguably, a comprehensive solution would use mmu_gather interface to
batch the TLB flushes and the PMDs page release, however it is not an
easy solution: (1) try_to_unmap_one() and try_to_migrate_one() also call
huge_pmd_unshare() and they cannot use the mmu_gather interface; and (2)
deferring the release of the page reference for the PMDs page until
after i_mmap_rwsem is dropeed can confuse huge_pmd_unshare() into
thinking PMDs are shared when they are not.

Fix __unmap_hugepage_range() by adding the missing TLB flush, and
forcing a flush when unshare is successful.

The ARCH_FEATURES function ID is a 32-bit SMC call, which returns
a 32-bit result per the SMCCC spec.  Current code is doing a 64-bit
comparison against -1 (SMCCC_RET_NOT_SUPPORTED) to detect that the
feature is unimplemented.  That check doesn't work in a Hyper-V VM,
where the upper 32-bits are zero as allowed by the spec.

Cast the result as an 'int' so the comparison works. The change also

With the CONFIG_HARDENED_USERCOPY option enabled, this patch triggers
kernel bugs at runtime:

  usercopy: Kernel memory overwrite attempt detected to kernel text (offset 2084839, size 6)!
  kernel BUG at mm/usercopy.c:99!
 Backtrace:
  IAOQ[0]: usercopy_abort+0xc4/0xe8

The problem is, that we have an init section of at least 2MB size which
starts at _stext and is freed after bootup.

If then later some kernel data is (temporarily) stored in this free
memory, check_kernel_text_object() will trigger a bug since the data
appears to be inside the kernel text (>=_stext) area:
        if (overlaps(ptr, len, _stext, _etext))

  perf/x86/intel/uncore: Fix filter_tid mask for CHA events on Skylake Server

Pull more powerpc fixes from Michael Ellerman:

 - Fix a bug in copying of sigset_t for 32-bit systems, which caused X
   to not start.

 - Fix handling of shared LSIs (rare) with the xive interrupt controller
   (Power9/10).

 - Fix missing TOC setup in some KVM code, which could result in oopses
   depending on kernel data layout.

 - Fix DMA mapping when we have persistent memory and only one DMA
   window available.

 - Fix further problems with STRICT_KERNEL_RWX on 8xx, exposed by a
   recent fix.

 - A couple of other minor fixes.
