Subject: [PATCH] powerpc/64: Free up CPU_FTR_ICSWX
Date: Thu, 19 Oct 2017 15:08:19 +1100 [thread overview]
Message-ID: <1508386099-2126-1-git-send-email-mpe@ellerman.id.au> (raw)
The last user of CPU_FTR_ICSWX was removed in commit
6ff4d3e96652 ("powerpc: Remove old unused icswx based coprocessor
support"), so free the bit up for future use.
Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
