From mboxrd@z Thu Jan 1 00:00:00 1970 From: Marc Zyngier Subject: [PATCH 50/85] KVM: arm/arm64: Move arm64-only vgic-v2-sr.c file to arm64 Date: Wed, 28 Mar 2018 13:52:19 +0100 Message-ID: <20180328125254.31380-51-marc.zyngier@arm.com> References: <20180328125254.31380-1-marc.zyngier@arm.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Cc: Christoffer Dall , Christoffer Dall , Shunyong Yang , Julien Thierry , Andre Przywara , Will Deacon , Shih-Wei Li , Catalin Marinas , Dave Martin To: Paolo Bonzini , =?UTF-8?q?Radim=20Kr=C4=8Dm=C3=A1=C5=99?= , kvmarm@lists.cs.columbia.edu, linux-arm-kernel@lists.infradead.org, kvm@vger.kernel.org Return-path: In-Reply-To: <20180328125254.31380-1-marc.zyngier@arm.com> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: kvmarm-bounces@lists.cs.columbia.edu Sender: kvmarm-bounces@lists.cs.columbia.edu List-Id: kvm.vger.kernel.org From: Christoffer Dall The vgic-v2-sr.c file now only contains the logic to replay unaligned accesses to the virtual CPU interface on 16K and 64K page systems, which is only relevant on 64-bit platforms. Therefore move this file to the arm64 KVM tree, remove the compile directive from the 32-bit side makefile, and remove the ifdef in the C file. Since this file also no longer saves/restores anything, rename the file to vgic-v2-cpuif-proxy.c to more accurately describe the logic in this file.
