Linus Torvalds e468f5c06b The Compiler Attributes series
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.
