[PATCH 2/3] kvm: x86: use a uapi-friendly macro for BIT

From: Paolo Bonzini
Date: Wed Jan 31 2024 - 17:50:38 EST


From: Dionna Glaze <dionnaglaze@xxxxxxxxxx>

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.
