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: # compiler-gcc: remove comment about gcc 4.5 from unreachable() # compiler.h: update definition of unreachable() #
