One possible solution would be to let the "scripts/headers_install.pl"

I'm not an expert of Perl regular expressions, but maybe this:
$line =~ s/\s__packed;$/ __attribute__((packed));/g
is a little bit closer to the intention?

Maybe:

s/\b__packed\b/__attribute__((packed))/g

Markus, will you post a patch with this fix?


though this argues against redefining
gcc __attributes__ in the first place.

It's a handy shortcut, so why not have it. Although I don't understand why checkpatch.pl has to warn about __attribute__((packed)).
