I can use a topic branch for patch 1 to apply patch 2. git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86/cpufeature contains that patch now (nothing else for now): 06b35d93af0a: x86/cpufeature: Add AVX512_VPOPCNTDQ feature So you can pull that into your tree as a base for the other one.
