Subject: [PATCH v1 4/9] x86/cpuid: Rename hypervisor_cpuid_base() to cpuid_hypervisor_base()
In order to let all the APIs under <cpuid/api.h> have a shared "cpuid_"
namespace, rename hypervisor_cpuid_base() to cpuid_hypervisor_base().
To align with the new style, also rename:
for_each_possible_hypervisor_cpuid_base(function)
to:
for_each_possible_cpuid_hypervisor_base(function)
Adjust all call-sites accordingly.
Suggested-by: Ingo Molnar <mingo@...nel.org>
