ARM: fix kill( ,SIGFPE) breakage
Commit 7771c6645700 ("signal/arm: Document conflicts with SI_USER and SIGFPE") broke the siginfo structure for userspace triggered signals, causing the strace testsuite to regress. Fix this by eliminating the FPE_FIXME definition (which is at the root of the breakage) and use FPE_FLTINV instead for the case where the hardware appears to be reporting nonsense. Fixes: 7771c6645700 ("signal/arm: Document conflicts with SI_USER and SIGFPE") Suggested-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
