[MIPS] Retry {save,restore}_fp_context if failed in atomic context. 2007-04-20T13:58:37+00:00 Atsushi Nemoto anemo@mba.ocn.ne.jp 2007-04-16T14:19:44+00:00 faea62346444ce5b1dba8fb5291d95b676522c42 The save_fp_context()/restore_fp_context() might sleep on accessing user stack and therefore might lose FPU ownership in middle of them. If these function failed due to "in_atomic" test in do_page_fault, touch the sigcontext area in non-atomic context and retry these save/restore operation. This is a replacement of a (broken) fix which was titled "Allow CpU exception in kernel partially".
