Subject: [PATCH 1/2] x86/cpufeatures: Put the AMX macros in the word 18 block
Date: Thu,  3 Feb 2022 11:43:07 -0800	[thread overview]
Message-ID: <20220203194308.2469117-1-jmattson@google.com> (raw)

These macros are for bits in CPUID.(EAX=7,ECX=0):EDX, not for bits in
CPUID(EAX=7,ECX=1):EAX. Put them with their brethren.
