Subject: sh: Handle a NULL vma in __update_tlb() for the fast-path.
X-Git-Tag: v2.6.32-rc1~640^2~82
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3ed6e129390fb872c3b7e05a232e5d380fbdfb48;p=pandora-kernel.git

sh: Handle a NULL vma in __update_tlb() for the fast-path.

The TLB miss fast-path presently calls in to update_mmu_cache() to
set up the entry, and does so with a NULL vma. Check for vma validity
in the __update_tlb() ptrace checks.
