[PATCH v3 9/9] MIPS: KVM: Remove dead code of TLB index error in kvm_mips_emul_tlbwr()

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

 



From: James Hogan <james.hogan@xxxxxxxxxx>

It's impossible to fall into the error handling of the TLB index after
being masked by (KVM_MIPS_GUEST_TLB_SIZE - 1). Remove the dead code.
