Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc
* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc: (209 commits) [POWERPC] Create add_rtc() function to enable the RTC CMOS driver [POWERPC] Add H_ILLAN_ATTRIBUTES hcall number [POWERPC] xilinxfb: Parameterize xilinxfb platform device registration [POWERPC] Oprofile support for Power 5++ [POWERPC] Enable arbitary speed tty ioctls and split input/output speed [POWERPC] Make drivers/char/hvc_console.c:khvcd() static [POWERPC] Remove dead code for preventing pread() and pwrite() calls [POWERPC] Remove unnecessary #undef printk from prom.c [POWERPC] Fix typo in Ebony default DTS [POWERPC] Check for NULL ppc_md.init_IRQ() before calling [POWERPC] Remove extra return statement [POWERPC] pasemi: Don't auto-select CONFIG_EMBEDDED [POWERPC] pasemi: Rename platform [POWERPC] arch/powerpc/kernel/sysfs.c: Move NUMA exports [POWERPC] Add __read_mostly support for powerpc [POWERPC] Modify sched_clock() to make CONFIG_PRINTK_TIME more sane [POWERPC] Create a dummy zImage if no valid platform has been selected [POWERPC] PS3: Bootwrapper support. [POWERPC] powermac i2c: Use mutex [POWERPC] Schedule removal of arch/ppc ... Fixed up conflicts manually in: Documentation/feature-removal-schedule.txt arch/powerpc/kernel/pci_32.c arch/powerpc/kernel/pci_64.c include/asm-powerpc/pci.h and asked the powerpc people to double-check the result..
