Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc
* 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc: (408 commits) [POWERPC] Add memchr() to the bootwrapper [POWERPC] Implement logging of unhandled signals [POWERPC] Add legacy serial support for OPB with flattened device tree [POWERPC] Use 1TB segments [POWERPC] XilinxFB: Allow fixed framebuffer base address [POWERPC] XilinxFB: Add support for custom screen resolution [POWERPC] XilinxFB: Use pdata to pass around framebuffer parameters [POWERPC] PCI: Add 64-bit physical address support to setup_indirect_pci [POWERPC] 4xx: Kilauea defconfig file [POWERPC] 4xx: Kilauea DTS [POWERPC] 4xx: Add AMCC Kilauea eval board support to platforms/40x [POWERPC] 4xx: Add AMCC 405EX support to cputable.c [POWERPC] Adjust TASK_SIZE on ppc32 systems to 3GB that are capable [POWERPC] Use PAGE_OFFSET to tell if an address is user/kernel in SW TLB handlers [POWERPC] 85xx: Enable FP emulation in MPC8560 ADS defconfig [POWERPC] 85xx: Killed <asm/mpc85xx.h> [POWERPC] 85xx: Add cpm nodes for 8541/8555 CDS [POWERPC] 85xx: Convert mpc8560ads to the new CPM binding. [POWERPC] mpc8272ads: Remove muram from the CPM reg property. [POWERPC] Make clockevents work on PPC601 processors ... Fixed up conflict in Documentation/powerpc/booting-without-of.txt manually.
