[PATCH 3/5] powerpc/pseries: Remove MPIC from pseries kexec
flat view
STALE3792d
From: Rashmica Gupta <hidden>
Date: 2016-05-30 06:18:51
Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Linus Torvalds
MPIC was only used by Power3 which is now unsupported, so remove MPIC
code. XICS is now the only supported interrupt controller for
pSeries so do some cleanups too.
