MIPS page fault path(except huge page) takes 3 exceptions (1 TLB Miss + 2
TLB Invalid), butthe second TLB Invalid exception is just triggered by
__update_tlb from do_page_fault writing tlb without _PAGE_VALID set.  With
this patch, user space mapping prot is made young by default (with both
_PAGE_VALID and _PAGE_YOUNG set), and it only take 1 TLB Miss + 1 TLB
Invalid exception

Remove pte_sw_mkyoung without polluting MM code and make page fault delay
of MIPS on par with other architecture

Hey Stephen,

Thanks for that, it's due to .noinstr section being put on the other
side of .text, so all our interrupt handler asm code can't reach them
directly anymore since the ppc interrupt wrappers patch added noinstr
attribute.

That's not strictly required though, we've used NOKPROBE_SYMBOL okay
until now. If you can take this patch for now, it should get
allyesconfig to build again. I'll fix it in the powerpc tree before the
merge window.

Thanks,
Nick
