d6c71dd061 Fix preprocessor indentation
Indent the C preprocessor directives to reflect their nesting
using the following script:

$ cppi -l $(git grep -El '^[[:space:]]*#[[:space:]]*(if|ifdef|ifndef|elif|else|endif|define|pragma)[[:space:]]' |grep -v '\.sh$') |while read f; do
	cppi < "$f" > "$f".cppi; mv "$f".cppi "$f"
done

7fa3d78319 Automatically replace kernel_(scno|ureg)_t with kernel_ulong_t
Remove temporary types created for transition from long
to kernel_ulong_t.

Automatically replace kernel_scno_t and kernel_ureg_t with

  xargs sed -ri 's/kernel_(scno|ureg)_t/kernel_ulong_t/g'

38a34c9349 Add copyright headers to some files which lack them
Before this change, all files that exist since 20th century had
copyright headers, while most files that appeared later didn't.  This
change fixes the inconsistency by adding missing copyright headers.

It doesn't mean that copyright headers became maintained.  In my view,
git history provides much better information on this subject and is much
more accurate than copyright headers.
