X-Git-Tag: v2.6.30-rc7~15^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a5e696e5d0f1377ff6beb10d2f40edb6a3d1de18;p=pandora-kernel.git MIPS: 64-bit: Fix system lockup. The address range size calculation inside local_flush_tlb_kernel_range() is being truncated by a too small size variable holder on 64-bit systems. The truncated size can result in an erroneous tlbsize check that means we sit spinning inside a loop trying to flush a hige number of TLB entries. This is for all intents and purposes a system hang. Fix by using an appropriately sized valiable to hold the size. [Ralf: Greg's original patch submission identified the issue and fixed one instance in tlb-r4k.c but there there were several more. For consistency I also modified tlb-r3k.c even though that file is only used on 32-bit.] Signed-off-by: Greg Ungerer Signed-off-by: Ralf Baechle --- Reading git-diff-tree failed
