Subject: [PATCH v6 04/90] treewide: Explicitly include the x86 CPUID headers
Date: Fri, 27 Mar 2026 03:15:18 +0100

Modify all CPUID call sites which implicitly include any of the CPUID
headers to explicitly include them instead.

For KVM's reverse_cpuid.h, just include <asm/cpuid/types.h> since it
references the CPUID_EAX..EDX symbols without using the CPUID APIs.

Note, this allows removing the inclusion of <asm/cpuid/api.h> from within
<asm/processor.h> next.  That allows the CPUID API headers to include
<asm/processor.h> without introducing a circular dependency.
