Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: powerpc/mm: Lockless get_user_pages_fast() for 64-bit (v3) powerpc: Don't use the wrong thread_struct for ptrace get/set VSX regs powerpc: Fix ptrace buffer size for VSX powerpc: Correctly hookup PTRACE_GET/SETVSRREGS for 32 bit processes ide/powermac: Fix use of uninitialized pointer on media-bay powerpc: Allow non-hcall return values for lparcfg writes ipmi/powerpc: Use linux/of_{device,platform}.h instead of asm powerpc/fsl: proliferate simple-bus compatibility to soc nodes Documentation: remove old sbc8260 board specific information cpm2: Rework baud rate generators configuration to support external clocks. powerpc: rtc_cmos_setup: assign interrupts only if there is i8259 PIC cpm_uart: Add generic clock API support to set baudrates cpm_uart: Modem control lines support powerpc: implement GPIO LIB API on CPM1 Freescale SoC. cpm2: Implement GPIO LIB API on CPM2 Freescale SoC. powerpc: Fix 8xx build failure powerpc: clean up the Book-E HW watchpoint support
