tools headers: Update the arch/x86/lib/memset_64.S copy with the kernel sources

2025-04-10T16:28:25Z

To pick up the changes in: 2981557cb0408e14 x86,kcfi: Fix EXPORT_SYMBOL vs kCFI That required adding a copy of include/linux/cfi_types.h and its checking in tools/perf/check-headers.h. Addressing this perf tools build warning: Warning: Kernel ABI header differences: diff -u tools/arch/x86/lib/memset_64.S arch/x86/lib/memset_64.S Please see tools/include/uapi/README for further details.

x86/cpufeatures: Remove {disabled,required}-features.h

2025-03-19T10:15:12Z

The functionalities of {disabled,required}-features.h have been replaced with the auto-generated generated/ header. Thus they are no longer needed and can be removed. None of the macros defined in {disabled,required}-features.h is used in tools, delete them too.

perf tools: Create generic syscall table support

2025-01-09T15:49:49Z

Currently each architecture in perf independently generates syscall headers. Adapt the work that has gone into unifying syscall header implementations in the kernel to work with perf tools. Introduce this framework with riscv at first. riscv previously relied on libaudit, but with this change, perf tools for riscv no longer needs this external dependency.
