[GIT PULL] x86/cpu for v7.3-rc1
From: Borislav Petkov
Date: Tue Aug 18 2026 - 14:47:58 EST
Hi Linus,
please pull the x86/cpu lineup for v7.3-rc1.
This is conflicting with other work from tip, see end of mail for possible
resolution.
Thx.

x86/CPU: Rename struct cpuid_read_output to struct cpuid_output (2026-08-05 07:40:33 -0700)
----------------------------------------------------------------
- Get rid of static_cpu_has() - one less API to care about testing CPU
features
- Unify the handling of CPU core types (performance, efficient, etc) by
mapping the vendor-specific types to Linux ones
- Continuation of the work of Ahmed Darwish to centralize CPUID leafs
representation
----------------------------------------------------------------
Ahmed S. Darwish (4):
x86/cpu/transmeta: Rescan CPUID(0x1) after modifying capabilities
x86/cpu: Use parsed CPUID(0x0)
x86/lib: Add CPUID(0x1) family and model calculation
x86/cpu: Use parsed CPUID(0x1)
Borislav Petkov (AMD) (4):
x86/cpu: Hide and rename static_cpu_has()
x86/topo: Map vendor CPU types to generic Linux such types
x86/cpu/scattered: Sort it properly
x86/CPU: Rename struct cpuid_read_output to struct cpuid_output
Pawan Gupta (1):
x86/bugs: Don't use cpu-type matching in cpu_vuln_blacklist
Vishal Badole (2):
x86/topology: Name the AMD core-type values
x86/topology: Add TOPO_CPU_TYPE_LOW_POWER
