[PATCH] kvm: x86: use a uapi-friendly macro for BIT

From: Dionna Glaze
Date: Wed Dec 06 2023 - 19:12:10 EST


Change uapi header uses of BIT to instead use the uapi/linux/const.h bit
macros, since BIT is not defined in uapi headers.

The PMU mask uses _BITUL since it targets a 32 bit flag field, whereas
the longmode definition is meant for a 64 bit flag field.
