Re: [PATCH v2 2/7] KVM: X86: Use _BITUL() macro in UAPI headers

From: Joe Richey <redacted>

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")
