Copy these from Linux v5.7-rc5 tag. This brings in some handy new attributes and is otherwise important to keep in sync. We drop the reference to smp_read_barrier_depends() as it is not relevant on the architectures we support at this time, based on where it's implemented in Linux today. We drop the call to kasan_check_read() as that is not relevant to U-Boot as well. Cc: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Tom Rini <trini@konsulko.com>
