There are some good comments about bitmap operations in lib/bitmap.c
and include/linux/bitmap.h, so format them for document generation and
pull them into core-api/kernel-api.rst.

I converted the "tables" of functions from using tabs to using spaces
so that they are more readable in the source file and in the generated
output.

Tom Saeger says:

Recently, while reading up on binfmt I attempted to open a document ref
only to find it was invalid.  I did a quick grep, found all the
binfmt_misc related broken refs and sent a patch.

Fine. Easy.

Then I wondered, "how many broken doc refs are there?".

Turns out with all the recent doc moves, quite a few.

I went about fixing just those found in Documentation/,
except those in Documentation/translations/ and
Documentation/devicetree/ for now.

Most of these changes were s/txt/rst/ or fixing up a path to an obvious
new location.  Some required going back to v4.10 v4.4 or some other
version to sleuth-out what content was actually being referenced and
then fixing the reference to point to the new file with that content.

Add a simple script and build target to do a treewide grep for
references to files under Documentation, and report the non-existing
file in stderr. It tries to take into account punctuation not part of
the filename, and wildcards, but there are bound to be false positives
too. Mostly seems accurate though.

We've moved files around enough to make having this worthwhile.

Way back in 2008 we didn't have "robust" in-kernel documentation system,
so the idea of putting something like the kernel driver statement in the
kernel tree wasn't even imagined.  But now that has changed, so add the
old document to the kernel source itself to allow for us to properly
reference it in one canonical place (as the LF wiki keeps moving things
around.)

This also will allow people to add their names to it, as I seem to have
lost the ability to do that by not knowing how to edit things on the
original document.

The existing message
	"Excess struct/union/enum/typedef member [...]"
made it sound like this would already be done, but the
code is never invoked for enums or typedefs (and really
can't be).

Add some code to the enum dumper to handle this there
instead.

While at it, also make the above message more accurate
by simply dumping the type that was passed in, and pass
the struct/union differentiation in.
