Subject: sh: Use local TLB flush in set_pte_phys().
X-Git-Tag: v2.6.31-rc1~30^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=997d0030934f7722d81e5b1cdd7af85ac7ed960b;p=platform%2Fkernel%2Flinux-3.10.git

sh: Use local TLB flush in set_pte_phys().

set_pte_phys() presently uses the global flush_tlb_one(), which locks on
SMP trying to do the IPI. As we have not even initialized the other CPUs
at this point, switch to the local_ variant so the flush happens on the
boot CPU.
