Pull percpu fixes from Tejun Heo:
"Rather important fixes this time.
- The new percpu area allocator had a subtle bug in how it iterates
the memory regions and could skip viable areas, which led to
allocation failures for module static percpu variables. Dennis
fixed the bug and another non-critical one in stat calculation.
- Mark noticed that the generic implementations of percpu local
atomic reads aren't properly protected against irqs and there's a
(slim) chance for split reads on some 32bit systems. Generic
implementations are updated to disable irq when read size is larger
than ulong size. This may have made some 32bit archs which can do
atomic local 64bit accesses generate sub-optimal code. We need to
find them out and implement arch-specific overrides"
* 'for-4.14-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu:
percpu: fix iteration to prevent skipping over block
