Hi Linus,

There are 2 minor changes to the percpu allocator this merge window:
 * for loop condition that could be out of bounds on multi-socket UP
 * cosmetic removal of pcpu_group_offsets[0] in UP code as it is 0

There has been an interest in having better alignment with percpu
allocations. This has caused a performance regression in at least 1
reported workload. I have a series out which adds scan hints to the
allocator as well as some other performance oriented changes. I hope to
have this queued for v5.2 soon.

Thanks,
Dennis
