Subject: [PATCH 0/2] High-order per-cpu cache v6

Changelog since v5
o Changelog clarification in patch 1
o Additional comments in patch 2

Changelog since v4
o Avoid pcp->count getting out of sync if struct page gets corrupted

Changelog since v3
o Allow high-order atomic allocations to use reserves

Changelog since v2
o Correct initialisation to avoid -Woverflow warning

The following is two patches that implement a per-cpu cache for high-order
allocations, primarily aimed at SLUB. The first patch is a bug fix that
is technically unrelated but was discovered by review and so batched
together. The second is the patch that implements the high-order pcpu cache.
