From: Joe Richey <joerichey@xxxxxxxxxx>
[ Upstream commit d06aca989c243dd9e5d3e20aa4e5c2ecfdd07050 ]
Replace BIT() in x86's UAPI header with _BITUL(). BIT() is not defined
in the UAPI headers and its usage may cause userspace build errors.
Fixes: 742c45c3ecc9 ("x86/elf: Enumerate kernel FSGSBASE capability in AT_HWCAP2")
