[PATCH] selftests: KVM: aarch64: Let hypercalls use UAPI *_BIT_COUNT

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

 



The hypercalls test currently defines its own *_BMAP_BIT_MAX macros to
define the last valid feature bit for each bitmap firmware register.
However, since these definitions are already present in the uapi header,
kvm.h, as *_BMAP_BIT_COUNT, and would help to keep the test updated as
features grow, use these instead.

No functional change intended.
