KVM: MIPS: Hardcode callbacks to hardware virtualization extensions

2022-12-29T20:41:12+00:00

Now that KVM no longer supports trap-and-emulate (see commit 45c7e8af4a5e "MIPS: Remove KVM_TE support"), hardcode the MIPS callbacks to the virtualization callbacks. Harcoding the callbacks eliminates the technically-unnecessary check on non-NULL kvm_mips_callbacks in kvm_arch_init(). MIPS has never supported multiple in-tree modules, i.e. barring an out-of-tree module, where copying and renaming kvm.ko counts as "out-of-tree", KVM could never encounter a non-NULL set of callbacks during module init. The callback check is also subtly broken, as it is not thread safe, i.e. if there were multiple modules, loading both concurrently would create a race between checking and setting kvm_mips_callbacks. Given that out-of-tree shenanigans are not the kernel's responsibility, hardcode the callbacks to simplify the code.

MIPS: KVM: Rename files to remove the prefix "kvm_" and "kvm_mips_"

2014-06-30T14:52:03+00:00

Since all the files are in arch/mips/kvm/, there's no need of the prefixes "kvm_" and "kvm_mips_". Reviewed-by: James Hogan Signed-off-by: Deng-Cheng Zhu Signed-off-by: Paolo Bonzini
