#     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")
