Sashiko AI review found 1 potential issue(= s) to consider: - [Low] x86/cpufeatures: missing tools header synchronization for X86_FEATU= RE_PLZA -- commit 4774876a98b5fdbef10f6f59346ad4e8b9b8b7ac Author: Babu Moger x86/cpufeatures: Support Privilege Level Zero Association (PLZA) This commit adds support for the Privilege Level Zero Association (PLZA) feature on AMD processors. It updates the cpufeatures header and the scattered CPUID bits to detect and expose PLZA.

The tools/perf build process runs check-headers.sh, which strictly checks for synchronization between arch/x86/include/asm/cpufeatures.h and its copy in tools/arch/x86/include/asm/cpufeatures.h. Failing to synchronize the tools copy will result in a "Kernel ABI header differs" build warning when compiling perf from this commit or anywhere later in the series. --=20 Sashiko AI review =C2=B7 https://sashiko.dev/#/patchset/cover.1790867441.gi= t.babu.moger@amd.com?part=3D1
