perf bench futex: Remove support for IMMUTABLE

2025-07-11T14:02:01Z

It has been decided to remove the support IMMUTABLE futex. perf bench was one of the eary users for testing purposes. Now that the API is removed before it could be used in an official release, remove the bits from perf, too. Remove Remove support for IMMUTABLE futex.

perf beauty: Move prctl.h files (uapi/linux and x86's) copy out of the directory used to build perf

2024-03-21T13:41:27Z

It is used only to generate string tables, not to build perf, so move it to the tools/perf/trace/beauty/{include,arch}/ hierarchies, that is used just for scraping. This is a something that should've have happened, as happened with the linux/socket.h scrapper, do it now as Ian suggested while doing an audit/refactor session in the headers used by perf. No other tools/ living code uses it, just coming from either 'make install_headers' or from the system /usr/include/ directory.
