Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (106 commits) powerpc/p3060qds: Add support for P3060QDS board powerpc/83xx: Add shutdown request support to MCU handling on MPC8349 MITX powerpc/85xx: Make kexec to interate over online cpus powerpc/fsl_booke: Fix comment in head_fsl_booke.S powerpc/85xx: issue 15 EOI after core reset for FSL CoreNet devices powerpc/8xxx: Fix interrupt handling in MPC8xxx GPIO driver powerpc/85xx: Add 'fsl,pq3-gpio' compatiable for GPIO driver powerpc/86xx: Correct Gianfar support for GE boards powerpc/cpm: Clear muram before it is in use. drivers/virt: add ioctl for 32-bit compat on 64-bit to fsl-hv-manager powerpc/fsl_msi: add support for "msi-address-64" property powerpc/85xx: Setup secondary cores PIR with hard SMP id powerpc/fsl-booke: Fix settlbcam for 64-bit powerpc/85xx: Adding DCSR node to dtsi device trees powerpc/85xx: clean up FPGA device tree nodes for Freecsale QorIQ boards powerpc/85xx: fix PHYS_64BIT selection for P1022DS powerpc/fsl-booke: Fix setup_initial_memory_limit to not blindly map powerpc: respect mem= setting for early memory limit setup powerpc: Update corenet64_smp_defconfig powerpc: Update mpc85xx/corenet 32-bit defconfigs ... Fix up trivial conflicts in: - arch/powerpc/configs/40x/hcu4_defconfig removed stale file, edited elsewhere - arch/powerpc/include/asm/udbg.h, arch/powerpc/kernel/udbg.c: added opal and gelic drivers vs added ePAPR driver - drivers/tty/serial/8250.c moved UPIO_TSI to powerpc vs removed UPIO_DWAPB support
