After the SPDX license tags were added a number of tooling headers got out of
sync with their kernel variants, generating lots of build warnings.

Sync them:

 - tools/arch/x86/include/asm/disabled-features.h,
   tools/arch/x86/include/asm/required-features.h,
   tools/include/linux/hash.h:

     Remove the SPDX tag where the kernel version does not have it.

 - tools/include/asm-generic/bitops/__fls.h,
   tools/include/asm-generic/bitops/arch_hweight.h,
   tools/include/asm-generic/bitops/const_hweight.h,
   tools/include/asm-generic/bitops/fls.h,
   tools/include/asm-generic/bitops/fls64.h,
   tools/include/uapi/asm-generic/ioctls.h,
   tools/include/uapi/asm-generic/mman-common.h,
   tools/include/uapi/sound/asound.h,
   tools/include/uapi/linux/kvm.h,
   tools/include/uapi/linux/perf_event.h,
   tools/include/uapi/linux/sched.h,
   tools/include/uapi/linux/vhost.h,
   tools/include/uapi/sound/asound.h:

     Add the SPDX tag of the respective kernel header.

 - tools/include/uapi/linux/bpf_common.h,
   tools/include/uapi/linux/fcntl.h,
   tools/include/uapi/linux/hw_breakpoint.h,
   tools/include/uapi/linux/mman.h,
   tools/include/uapi/linux/stat.h,

     Change the tag to the kernel header version:

       -/* SPDX-License-Identifier: GPL-2.0 */
       +/* SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note */

Also sync other header details:

 - include/uapi/sound/asound.h:

     Fix pointless end of line whitespace noise the header grew in this cycle.

 - tools/arch/x86/lib/memcpy_64.S:

     Sync the code and add tools/include/asm/export.h with dummy wrappers
     to support building the kernel side code in a tooling header environment.

 - tools/include/uapi/asm-generic/mman.h,
   tools/include/uapi/linux/bpf.h:

     Sync other details that don't impact tooling's use of the ABIs.
