Subject: LoongArch: KVM: Use CSR_CRMD_PLV in kvm_arch_vcpu_in_kernel()
X-Git-Url: http://git.ipfire.org/index.cgi?a=commitdiff_plain;h=da773ea3f59032f659bfc4c450ca86e384786168;p=thirdparty%2Fkernel%2Flinux.git

LoongArch: KVM: Use CSR_CRMD_PLV in kvm_arch_vcpu_in_kernel()

The function reads LOONGARCH_CSR_CRMD but uses CSR_PRMD_PPLV to
extract the privilege level. While both masks have the same value
(0x3), CSR_CRMD_PLV is the semantically correct constant for CRMD.
