Commit a7a9dcd882a67 ("powerpc: Avoid taking a data miss on every
userspace instruction miss") has shown that limiting the read of
faulting instruction to likely cases improves performance.
This patch goes further into this direction by limiting the read
of the faulting instruction to the only cas

Semantic changes are possible since the commit d83a7cb375eec21f04
("livepatch: change to a per-task consistency model").
Also data structures can be patched since the commit 439e7271dc2b63de37
("livepatch: introduce shadow variable API").
It is a high time we removed these limitations from the do
At the time being, memcmp() compares two chunks of memory
byte per byte.
This patch optimises the comparison by comparing word by word.
A small benchmark performed on an 8xx comparing two chuncks

For a PMD swap mapping, zap_huge_pmd() will clear the PMD and call
free_swap_and_cache() to decrease the swap reference count and maybe
free or split the huge swap cluster and the THP in swap cache.

Previously the huge swap cluster will be split after the THP is

Swapin a THP as a whole isn't desirable at some situations. For

inflate the reading greatly. So a sysfs interface:

It's unreasonable to optimize swapping for THP without basic swapping
support. And this will cause build errors when THP_SWAP functions are
defined in swapfile.c and called elsewhere.
