Subject: [git pull] Please pull powerpc.git next branch
Hi Linus !
Here's the powerpc batch for 3.6 merge window. Notable highlights:
- iommu improvements from Anton removing the per-iommu global lock
in favor of dividing the DMA space into pools, each with its own lock,
and hashed on the CPU number. Along with making the locking more fine
grained, this gives significant improvements in multiqueue networking
scalability.
- Still from Anton, we know provide a vdso based variant of getcpu
which makes sched_getcpu with the appropriate glibc patch something
like 18 times faster.
- More anton goodness (he's been busy !) in other areas such as a
faster __clear_user and copy_page on P7, various perf fixes to improve
sampling quality, etc...
- One more step toward removing legacy i2c interfaces by using
new device-tree based probing of platform devices for the AOA audio
drivers
- A nice series of patches from Michael Neuling that helps avoiding
confusion between register numbers and litterals in assembly code,
trying to enforce the use of "%rN" register names in gas rather than
plain numbers.
- A pile of FSL updates
- The usual bunch of small fixes, cleanups etc...
You may spot a change to drivers/char/mem. The patch got no comment or
ack from outside, it's a trivial patch to allow the architecture to
skip creating /dev/port, which we use to disable it on ppc64 that don't
have a legacy brige. On those, IO ports 0...64K are not mapped in kernel
space at all, so accesses to /dev/port cause oopses (and yes, distros
-still- ship userspace that bangs hard coded ports such as kbdrate).
Cheers,
Ben.
