Subject: [PATCH 5/5] x86/cpuid: Use u32 in instead of uint32_t in <asm/cpuid/api.h>

From: Ingo Molnar <mingo@...nel.org>

Use u32 instead of uint32_t in hypervisor_cpuid_base().

Yes, I realize uint32_t is used in Xen code et al, but this is
a core x86 architecture header and we should standardize on the
type that is being used overwhelmingly in related x86 architecture
code.

The two types are the same so there should be no build warnings.
