Masahiro Yamada d9c5252295 treewide: add "WITH Linux-syscall-note" to SPDX tag of uapi headers
UAPI headers licensed under GPL are supposed to have exception
"WITH Linux-syscall-note" so that they can be included into non-GPL
user space application code.

The exception note is missing in some UAPI headers.

Some of them slipped in by the treewide conversion commit b24413180f
("License cleanup: add SPDX GPL-2.0 license identifier to files with
no license"). Just run:

  $ git show --oneline b24413180f -- arch/x86/include/uapi/asm/

I believe they are not intentional, and should be fixed too.

This patch was generated by the following script:

  git grep -l --not -e Linux-syscall-note --and -e SPDX-License-Identifier \
    -- :arch/*/include/uapi/asm/*.h :include/uapi/ :^*/Kbuild |
  while read file
  do
          sed -i -e '/[[:space:]]OR[[:space:]]/s/\(GPL-[^[:space:]]*\)/(\1 WITH Linux-syscall-note)/g' \
          -e '/[[:space:]]or[[:space:]]/s/\(GPL-[^[:space:]]*\)/(\1 WITH Linux-syscall-note)/g' \
          -e '/[[:space:]]OR[[:space:]]/!{/[[:space:]]or[[:space:]]/!s/\(GPL-[^[:space:]]*\)/\1 WITH Linux-syscall-note/g}' $file
  done

After this patch is applied, there are 5 UAPI headers that do not contain
"WITH Linux-syscall-note". They are kept untouched since this exception
applies only to GPL variants.

  $ git grep --not -e Linux-syscall-note --and -e SPDX-License-Identifier \
