Subject: [PATCH v2 rebase 05/34] powerpc/64s/exception: Move all interrupt handlers to new style code gen macros
From: Nicholas Piggin <npiggin@...il.com>
Aside from label names and BUG line numbers, the generated code change
is an additional HMI KVM handler added for the "late" KVM handler,
because early and late HMI generation is achieved by defining two
different interrupt types.
