Subject: [RFC PATCH 08/16] KVM: PPC: e500: merge <asm/kvm_e500.h> into arch/powerpc/kvm/e500.h
Date: Tue, 20 Dec 2011 19:34:31 -0600	[thread overview]
Message-ID: <20111221013431.GH8378@schlenkerla.am.freescale.net> (raw)
In-Reply-To: <20111221013340.GA8368@schlenkerla.am.freescale.net>

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.
