powerpc/64s/exception: Fix 0x1500 interrupt handler crash # # A typo caused the interrupt handler to branch immediately to the # common "unknown interrupt" handler and skip the special case test for # denormal cause. # # This does not affect KVM softpatch handling (e.g., for POWER9 TM # assist) because the KVM test was moved to common code by commit # 9600f261acaa ("powerpc/64s/exception: Move KVM test to common code") # just before this bug was introduced. # # Fixes: 3f7fbd97d07d ("powerpc/64s/exception: Clean up SRR specifiers") # Reported-by: Paul Menzel # Signed-off-by: Nicholas Piggin # Tested-by: Paul Menzel # [mpe: Split selftest into a separate patch] # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20200708074942.1713396-1-npiggin@gmail.com # <
