Merge branches 'tracing/ftrace' and 'linus' into tracing/core

parents 4176935b ee568b25
This source diff could not be displayed because it is too large. You can view the blob instead.
This is the full-colour version of the currently unofficial Linux logo
("currently unofficial" just means that there has been no paperwork and
that I have not really announced it yet). It was created by Larry Ewing,
and is freely usable as long as you acknowledge Larry as the original
artist.
Note that there are black-and-white versions of this available that
scale down to smaller sizes and are better for letterheads or whatever
you want to use it for: for the full range of logos take a look at
Larry's web-page:

Tux is taking a three month sabbatical to work as a barber, so Tuz is
standing in. He's taken pains to ensure you'll hardly notice.
