From 35938a00ba86ae7a7404b66b526968ca2b8d3127 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Mon, 31 Oct 2016 16:25:44 +0000 Subject: [PATCH] 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.
