# Merge: baa888d25ea6 1ff2fea5e30c
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'compiler-attributes-for-linus-4.20-rc1' of https://github.com/ojeda/linux
#     
#     Pull compiler attribute updates from Miguel Ojeda:
#      "This is an effort to disentangle the include/linux/compiler*.h headers
#       and bring them up to date.
#     
#       The main idea behind the series is to use feature checking macros
#       (i.e. __has_attribute) instead of compiler version checks (e.g.
#       GCC_VERSION), which are compiler-agnostic (so they can be shared,
#       reducing the size of compiler-specific headers) and version-agnostic.
#     
#       Other related improvements have been performed in the headers as well,
#       which on top of the use of __has_attribute it has amounted to a
#       significant simplification of these headers (e.g. GCC_VERSION is now
#       only guarding a few non-attribute macros).
#     
#       This series should also help the efforts to support compiling the
#       kernel with clang and icc. A fair amount of documentation and comments
#       have also been added, clarified or removed; and the headers are now
#       more readable, which should help kernel developers in general.
#     
#       The series was triggered due to the move to gcc >= 4.6. In turn, this
#       series has also triggered Sparse to gain the ability to recognize
#       __has_attribute on its own.
#     
#       Finally, the __nonstring variable attribute series has been also
#       applied on top; plus two related patches from Nick Desaulniers for
#       unreachable() that came a bit afterwards"
#     
#     * tag 'compiler-attributes-for-linus-4.20-rc1' of https://github.com/ojeda/linux:
