-Benjamin Herrenschmidt has some powerpc fixes, Keith Packard has
fixes for drm-intel (“A bunch of patches which fix IVB-specific troubles:

* A selection of code which was labeled for SNB, but needs to be run on
IVB as well.

* A replacement for the quick-hack IVB lost-IRQ issue. This appears to
help on SNB as well, but for now it’s only enabled on IVB in case we
discover problems with it.

* Fix some 3-pipe issues

And, a couple of minor mode setting fixes.”) and Tyler Hicks has some ecryptfs
fixes for -rc2 :

Tim’s logging message update will be really helpful to users when
they’re trying to locate a problematic file in the lower filesystem with
filename encryption enabled.

You’ll recognize the fix from Li, as you commented on that.

You should also be familiar with my setattr/truncate improvements, since
you were the one that pointed them out to us (thanks again!). Andrew
noted the /dev/ecryptfs write count sanitization needed to be improved,
so I’ve got a fix in there for that along with some other less important
cleanups of the /dev/ecryptfs read/write code.

They’ve all sat in -next for at least a day, while some have been there
around a week, I believe.

I’ll get signed tags going for the next pull request I send. That was my
intention this time, but it just hit me that I forgot to do it.

-Greg KH announces the release of 2.6.32.55, 3.2.2 and 3.0.18, Dave Airlie
has some drm fixes, mostly radeon-related, Geert Uytterhoeven has m68k updates
for 3.3 and Ingo Molnar has core, perf and x86 fixes.

-Olof Johansson has arm-soc fixes for -rc, and this concludes this week’s news.
