Subject: [PATCH] powerpc: Remove suspect CONFIG_PPC_BOOK3E #ifdefs in nohash/64/pgtable.h
Date: Thu, 25 Aug 2016 14:31:10 +0800	[thread overview]
Message-ID: <1472106670-3432-1-git-send-email-rui.teng@linux.vnet.ibm.com> (raw)

There are three #ifdef CONFIG_PPC_BOOK3E sections in nohash/64/pgtable.h.
And there should be no configurations possible which use nohash/64/pgtable.h
but don't also enable CONFIG_PPC_BOOK3E.

Suggested-by: Michael Ellerman <mpe@ellerman.id.au>
