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()
This patchset looks awesome to me.
If you have a plan to respin, please CCed Peter.
Thanks for review.
I will wait more review and respin, the day after tomorrow.
Version 2 will include fix about your comment.
Could you pick up second version of this patchset?

[3] is changed to leave one blank line.
[4] is changed in order to further optimize according to Minchan's comment.
It return first index of flushed entry, instead of last index.
Others doesn't changed.
