pte_mkyoung() seems to be a strange place to set the pte's valid bit.
Why is it done there? Can it be done
On mips platform, hw PTE entry valid bit is set in pte_mkyoung

Here add pte_mkyoung function to make page readable on MIPS platform
during page fault handling. This patch improves page fault latency
