Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc updates from Benjamin Herrenschmidt:
"Some highlights in addition to the usual batch of fixes:
- 64TB address space support for 64-bit processes by Aneesh Kumar
- Gavin Shan did a major cleanup & re-organization of our EEH support
code (IBM fancy PCI error handling & recovery infrastructure) which
paves the way for supporting different platform backends, along
with some rework of the PCIe code for the PowerNV platform in order
to remove home made resource allocations and instead use the
generic code (which is possible after some small improvements to it
done by Gavin).
- Uprobes support by Ananth N Mavinakayanahalli
- A pile of embedded updates from Freescale folks, including new SoC
and board supports, more KVM stuff including preparing for 64-bit
BookE KVM support, ePAPR 1.1 updates, etc..."
