From: Takuya Yoshikawa<yoshikawa.takuya@xxxxxxxxxxxxx> This patch optimizes the guest page table walk by using get_user() instead of copy_from_user(). With this patch applied, paging64_walk_addr_generic() has become about 0.5us to 1.0us faster on my Phenom II machine with NPT on.
Applied, thanks. Care to send a follow-on patch that makes cmpxchg_gpte() use ptep_user instead of calculating it by itself?
