Subject: [PATCH 06/31] mips/kvm: Rename kvm_vcpu_arch.pc to kvm_vcpu_arch.epc
Date: Fri, 7 Jun 2013 16:03:10 -0700 [thread overview]
Message-ID: <1370646215-6543-7-git-send-email-ddaney.cavm@gmail.com> (raw)
In-Reply-To: <1370646215-6543-1-git-send-email-ddaney.cavm@gmail.com>
From: David Daney <david.daney@cavium.com>
The proper MIPS name for this register is EPC, so use that.
Change the asm-offsets name to KVM_VCPU_ARCH_EPC, so that the symbol
name prefix matches the structure name.
Signed-off-by: David Daney <david.daney@cavium.com>
