It is not necessary to flush tlb page on all CPUs if suitable PTE entry exists already during page fault handling, just updating TLB is fine. Here redefine flush_tlb_fix_spurious_fault as empty on MIPS system.
Need empty line here.
V6: - Add update_mmu_tlb function as empty on all platform except mips system, we use this function to update local tlb for page fault smp-race handling V5: - define update_mmu_cache function specified on MIPS platform, and add page fault smp-race stats info V4: - add pte_sw_mkyoung function to implement readable privilege, and this function is only in effect on MIPS system. - add page valid bit judgement in function pte_modify V3: - add detailed changelog, modify typo issue in patch V2 v2: - split flush_tlb_fix_spurious_fault and tlb update into two patches - comments typo modification - separate tlb update and add pte readable privilege into two patches
It was a bad idea to keep the version change log in the 1st patch only, we have either cover letter for that, or all the individual patches...
