[PATCH 0/3] Update reference to include/asm-<arch>

[Geert Uytterhoeven]

	Hi all,

Despite "include/asm-<arch>" having been replaced by
"arch/<arch>/include/asm" 15 years ago, there are still several
references left.

This patch series updates the most visible ones.

Thanks for your comments!

[PATCH 2/3] kbuild: Drop support for include/asm-<arch> in headers_check.pl

[Geert Uytterhoeven]

"include/asm-<arch>" was replaced by "arch/<arch>/include/asm" a long
time ago.  All assembler header files are now included using
"#include <asm/*>", so there is no longer a need to rewrite paths.

After this commit, the second argument $arch is no longer
used.

Please clean up

my ($dir, $arch, @files) = @ARGV;

Is this check still needed?

include/asm was a symlink to include/asm-<architecture> in the old days,
but it no longer exists.

In which case, is this check triggered?

"git grep include/asm- | grep -v generic"
will find more instances.

Someone might still try to create a header file under include/asm/.

I applied this with the follow-up squashed. Thanks.

This should be dropped from Andrew Morton's tree.
