[PATCH 5.12 130/296] KVM: X86: Use _BITUL() macro in UAPI headers

Greg Kroah-Hartman

From: Joe Richey <joerichey@google.com>

commit fb1070d18edb37daf3979662975bc54625a19953 upstream.

Replace BIT() in KVM's UPAI header with _BITUL(). BIT() is not defined
in the UAPI headers and its usage may cause userspace build errors.

Fixes: fb04a1eddb1a ("KVM: X86: Implement ring-based dirty memory tracking")
