Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc fixes from Benjamin Herrenschmidt: "I meant to sent that earlier but got swamped with other things, so here are some powerpc fixes for 3.6. A few regression fixes and some bug fixes that I deemed should still make it. There's a FSL update from Kumar with a bunch of defconfig updates along with a few embedded fixes. I also reverted my g5_defconfig update that I merged earlier as it was completely busted, not too sure what happened there, I'll do a new one later." * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: Revert "powerpc: Update g5_defconfig" powerpc/perf: Use pmc_overflow() to detect rolled back events powerpc: Fix VMX in interrupt check in POWER7 copy loops powerpc: POWER7 copy_to_user/copy_from_user patch applied twice powerpc: Fix personality handling in ppc64_personality() powerpc/dma-iommu: Fix IOMMU window check powerpc: Remove unnecessary ifdefs powerpc/kgdb: Restore current_thread_info properly powerpc/kgdb: Bail out of KGDB when we've been triggered powerpc/kgdb: Do not set kgdb_single_step on ppc powerpc/mpic_msgr: Add missing includes powerpc: Fix null pointer deref in perf hardware breakpoints powerpc: Fixup whitespace in xmon powerpc: Fix xmon dl command for new printk implementation powerpc/fsl: fix "Failed to mount /dev: No such device" errors powerpc/fsl: update defconfigs booke/wdt: some ioctls do not return values properly powerpc/p4080ds: dts - add usb controller version info and port0 powerpc/85xx: mpc85xx_defconfig - add VIA PATA support for MPC85xxCDS powerpc/fsl-pci: Only scan PCI bus if configured as a host
