Merge branch 'for-5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu

Pull percpu updates from Dennis Zhou:
 "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 one
  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"

* 'for-5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu:
  percpu: km: no need to consider pcpu_group_offsets[0]
  percpu: use nr_groups as check condition
