The FPU emulator includes 2 calls to pr_err() which are triggered by invalid instruction encodings for MIPSr6 cmp.cond.fmt instructions. These cases are not kernel errors, merely invalid instructions which are already handled by delivering a SIGILL which will provide notification that something failed in cases where that makes sense. In cases where that SIGILL is somewhat expected & being handled, for example when crashme happens to generate one of the affected bad encodings, the message is printed with no useful context about what triggered it & spams the kernel log for no good reason. Remove the pr_err() calls to make crashme run silently & treat the bad encodings the same way we do others, with a SIGILL & no further kernel log output. Signed-off-by:
