This patchset clean-up and optimize highmem related code.
Change from v1 Rebase on v3.7-rc3 [4] Instead of returning index of last flushed entry, return first index. And update last_pkmap_nr to this index to optimize more.
Summary for v1 [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 first flushed entry mm, highmem: get virtual address of the page using PKMAP_ADDR()
