[PATCH 06/31] mips/kvm: Rename kvm_vcpu_arch.pc to kvm_vcpu_arch.epc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: David Daney <david.daney@xxxxxxxxxx>

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@xxxxxxxxxx>
