Hi,
While trying to add loongarch to the Rust kvm-bindings crate, I
accidentally discovered faulty logic in the handling of CPUCFG IDs
("leaves" for those more familiar with x86), that could result in
incorrectly accepting every possible int for the ID; fortunately it is
6.8 material that hasn't seen a release yet, so a fix is possible.
The first two patches contain the fix, while the rest are general
drive-by refactoring and comment cleanups.
(As it is currently the Chinese holiday season, it is probably best for
this series to go through the kvm tree, instead of the loongarch one
even though they seem to like prefer collecting every loongarch patch.)
WANG Xuerui (5):
KVM: LoongArch: Fix input value checking of _kvm_get_cpucfg
KVM: LoongArch: Fix kvm_check_cpucfg incorrectly accepting bad CPUCFG
IDs
KVM: LoongArch: Rename _kvm_get_cpucfg to _kvm_get_cpucfg_mask
KVM: LoongArch: Streamline control flow of kvm_check_cpucfg
KVM: LoongArch: Clean up comments of _kvm_get_cpucfg_mask and
kvm_check_cpucfg
