Commit Message

Linus Walleij April 17, 2024, 8:30 a.m. UTC 
The cache functions to flush user cache (*_flush_user_cache_all)
and coherent kernel range (*_coherent_kern_range) are in many
cases just a branch to the corresponfing userspace or kernelspace
function. These functions also have the same arguments.

Simplify these two by using SYM_FUNC_ALIAS() in all affected sites.

The NOP cache has very many similar calls which are just returns,
but it would be confusing to use aliases here, so leave all the
explicit returns and drop a comment on why we are not using aliases.
