It is not necessary to flush tlb page on all CPUs if suitable PTE

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...
Sorry for noticing this only now. With 4 patches, you should have a cover
letter anyway...
