[PATCH v2 01/13] KVM: Move KVM_REG_SIZE() definition to common uAPI header

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

 



Define KVM_REG_SIZE() in the common kvm.h header, and delete the arm64 and
RISC-V versions.  As evidenced by the surrounding definitions, all aspects
of the register size encoding are generic, i.e. RISC-V should have moved
arm64's definition to common code instead of copy+pasting.
