hwpmc [0/13]

[Aggelos Economopoulos]

Hello,

this port of hwpmc (start here: http://wiki.freebsd.org/PmcTools) has
been stagnating on my hard disk for some months now. I'm finally
submitting it for inclusion because

a) the parts that work might be useful to someone and, more importantly,
b) complaints and bug reports might help get me off my butt and fix the
   remaining issues.

I've taken the time to split the patches so that people can review them
easily (the original freebsd code is submitted as .tgz since I'm not
interested in your review of that).

Please apply patches / extract tarballs in numerical order. I'll be a
bit surprised if there are no omissions/duplicate patches, but at least
my build test for world/kernel worked.

You will need these lines in your kernel config. See the manual pages
for usage examples.
