    tools arch s390: Do not include header files from the kernel sources · 10b9baa7
    Arnaldo Carvalho de Melo authored
    Long ago we decided to be verbotten including files in the kernel git
    sources from tools/ living source code, to avoid disturbing kernel
    development (and perf's and other tools/) when, say, a kernel hacker
    adds something, tests everything but tools/ and have tools/ build
    broken.
    
    This got broken recently by s/390, fix it by copying
    arch/s390/include/uapi/asm/perf_regs.h to tools/arch/s390/include/uapi/asm/,
    making this one be used by means of <asm/perf_regs.h> and updating
    tools/perf/check_headers.sh to make sure we are notified when the
    original changes, so that we can check if anything is needed on the
    tooling side.
    
    This would have been caught by the 'tarkpg' test entry in:
    
    $ make -C tools/perf build-test
    
    When run on a s/390 build system or container.
