Rozycki Date: Mon, 31 Oct 2016 16:25:44 +0000 (+0000) Subject: MIPS: Fix ISA I FP sigcontext access violation handling X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=35938a00ba86ae7a7404b66b526968ca2b8d3127;p=openwrt%2Fstaging%2Fblogic.git MIPS: Fix ISA I FP sigcontext access violation handling Complement commit 0ae8dceaebe3 ("Merge with 2.3.10.") and use the local `fault' handler to recover from FP sigcontext access violation faults, like corresponding code does in r4k_fpu.S. The `bad_stack' handler is in syscall.c and is not suitable here as we want to propagate the error condition up through the caller rather than killing the thread outright. Signed-off-by: Maciej W.
