Seems to be a better idea than trying to coordinate pulls from three

ADI feature on M7 and newer processors has three important properties

memory an ADI version tag applies to, (2) Number of uppermost bits in
virtual address used to encode ADI tag, and (3) The value M7 processor

SPARC M7 processor introduces a new feature - Application Data

When a rogue access occurs, MMU blocks the access and raises an
exception. In response to the exception, kernel sends the offending
task a SIGSEGV with si_code that ind

If a processor supports special metadata for a page, for example ADI
version tags on SPARC M7, this metadata must be saved when the page is
swapped out. The same metadata must be restored when the page is swapped
back in. This patch adds two new architecture specific functions -
arch_do_swap_page()
M7 and newer processors add a "Memory corruption Detected" trap with
the addition of ADI feature. This trap is vectored into kernel by HV
through resumable error trap with error attribute for the resumable
error set to 0x0800.

ADI is a new feature supported on SPARC M7 and newer processors to allow

SPARC M7 processor adds additional metadata for memory address space
that can be used to secure access to regions of memory. This additional

Add a jump target so that a bit of exception handling can be better reused
at the end of this function.
This issue was detected by using the Coccinelle software.

I fail to see the point of UFS_BIT(). So yes.
Please make sure to CC: Subhash on ufs changes.

ksm use jhash2 for hashing pages,
in 4.14 xxhash has been merged to mainline kernel.
xxhash much faster then jhash2 on big inputs (32 byte+)
xxhash has 2 versions, one with 32-bit hash and
one with 64-bit hash.
64-bit version works faster then 32-bit on 64-bit arch.
So lets get better from two
jhash2 used for calculating checksum
for in memory pages, for detect fact of
changes in page.
xxhash much faster then jhash2, some tests:
x86_64 host:
CPU: Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz
PAGE_SIZE: 4096, loop count: 1048576
jhash2: 0xacbc7a5btime: 1907 ms, th
xxh32() - fast on both 32/64-bit platforms
xxh64() - fast only on 64-bit platform
Create xxhash() which will pickup fastest version
on compile time.
As result depends on cpu word size,
the main proporse of that - in memory hashing.
