Subject: [PATCH 08/56] KVM: PPC: e500: merge <asm/kvm_e500.h> into arch/powerpc/kvm/e500.h
Date: Thu, 15 Mar 2012 12:10:37 +0000	[thread overview]
Message-ID: <1331813485-14722-9-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1331813485-14722-1-git-send-email-agraf@suse.de>

From: Scott Wood <scottwood@freescale.com>

Keeping two separate headers for e500-specific things was a
pain, and wasn't even organized along any logical boundary.

There was TLB stuff in <asm/kvm_e500.h> despite the existence of
arch/powerpc/kvm/e500_tlb.h, and nothing in <asm/kvm_e500.h> needed
to be referenced from outside arch/powerpc/kvm.
