Dave Chinner reported the following on https://lkml.org/lkml/2015/3/1/226
Across the board the 4.0-rc1 numbers are much slower, and the degradation
is far worse when using the large memory footprint configs. Perf points
straight at the cause - this is from 4.0-rc1 on the -o bhash=101073 config:
Base PTEs are marked young when the NUMA hinting information is cleared
but the same does not happen for huge pages which this patch addresses.
Note that migrated pages are not marked young as the base page migration
code does not assume that migrated pages have been referenced. This could

Why not simply revert it to see whether that cures much of the
problem?
So the problem with that is that pmd_set_numa() and friends simply
no longer exist. So we

Hmm. I *thought* this should be unnecessary. vm_page_prot alreadty has
the accessed bit set, and we kind of depend on the initial page table
setup

It makes no sense to use a variant lock token on a platform which
doesn't support for shared-processor logical partitions. Actually we
can eliminate a memory load by using a fixed lock token on these
platforms.

The wrong value is being returned by change_huge_pmd since commit
10c1045f28e8 (mm: numa: avoid unnecessary TLB flushes when setting
NUMA hinting entries) which allows a fallthrough that tries to adjust
non-existent PTEs. This patch corrects it.

Dave Chinner reported a problem due to excessive NUMA balancing activity
and bisected it. The first patch in this series corrects a major problem
that is unlikely to affect Dave but is still serious. Patch 2 is a minor
cleanup that was spotted while looking at scan rate control. Patch 3 is
minor
This code is dead since commit 9e645ab6d089 (sched/numa: Continue PTE
scanning even if migrate rate limited) so remove it.

All the cache line size of the current book3e 64bit SoCs are 64 bytes.
So we should use this size to align the member of paca_struct.
With this change we save 192 bytes. Also change it to __aligned(size)
since it is preferred over __attribute__((aligned(size))).
Before:

Looks obviously correct. The old code was just very wrong.
