Subject: [PATCH 0/5] minor clean-up and optimize highmem related code

This patchset clean-up and optimize highmem related code.

[1] is just clean-up and doesn't introduce any functional change.
[2-3] are for clean-up and optimization.
These eliminate an useless lock opearation and list management.
[4-5] is for optimization related to flush_all_zero_pkmaps().

Joonsoo Kim (5):
  mm, highmem: use PKMAP_NR() to calculate an index of pkmap
  mm, highmem: remove useless pool_lock
  mm, highmem: remove page_address_pool list
  mm, highmem: makes flush_all_zero_pkmaps() return index of last
    flushed entry
  mm, highmem: get virtual address of the page using PKMAP_ADDR()
