Merge tag 'compiler-attributes-for-linus-v5.0-rc7' of git://github.com/ojeda/linux
Pull compiler attributes fixes from Miguel Ojeda: "Clean the new GCC 9 -Wmissing-attributes warnings The upcoming GCC 9 release extends the -Wmissing-attributes warnings (enabled by -Wall) to C and aliases: it warns when particular function attributes are missing in the aliases but not in their target, e.g.: void __cold f(void) {} void __alias("f") g(void); diagnoses: warning: 'g' specifies less restrictive attribute than its target 'f': 'cold' [-Wmissing-attributes] These patch series clean these new warnings. Most of them are caused by the module_init/exit macros" Link: https://lore.kernel.org/lkml/20190125104353.2791-1-labbott@redhat.com/ * tag 'compiler-attributes-for-linus-v5.0-rc7' of git://github.com/ojeda/linux: include/linux/module.h: copy __init/__exit attrs to init/cleanup_module Compiler Attributes: add support for __copy (gcc >= 9) lib/crc32.c: mark crc32_le_base/__crc32c_le_base aliases as __pure
