dc8afdc7ad [POWERPC] XilinxFB: Move xilinxfb_platform_data definition to a shared header file
XilnixFB can be used by more than just arch/ppc.  Move the data structure
definition into include/linux/xilinxfb.h so it can be used by microblaze
and arch/powerpc

because it was getting called before it was ready.  This is a result
of commit "[POWERPC] pseries: Fix jumbled no_logging flag."

b41848031a [POWERPC] Celleb: Support for Power/Reset buttons
This supports Power/Reset buttons on Beat on Celleb.

On Beat, we have an event from Beat if Power button or Reset button
is pressed. This patch catches the event and convert it to a signal
to INIT process by calling ctrl_alt_del() function.

/sbin/inittab have no entry to turn the machine power off so we have
to detect if power button is pressed or not internally in our driver.
This idea is taken from PS3's event handling subsystem.

048c8bc90e [POWERPC] ppc64: support CONFIG_DEBUG_PREEMPT
Add CONFIG_DEBUG_PREEMPT support to ppc64: it was useful for testing
get_paca() preemption.  Cheat a little, just use debug_smp_processor_id()
in the debug version of get_paca(): it contains all the right checks and
reporting, though get_paca() doesn't really use smp_processor_id().

Use local_paca for what might have been called __raw_get_paca().
Silence harmless warnings from io.h and lparcfg.c with local_paca -
it is okay for iseries_lparcfg_data to be referencing shared_proc
with preemption enabled: all cpus should show the same value for
shared_proc.

Why do other architectures need TRACE_IRQFLAGS_SUPPORT for DEBUG_PREEMPT?
I don't know, ppc64 appears to get along fine without it.

3eb523b939 [POWERPC] Fix pci domain detection
The /proc/bus/pci/* files list PCI domain numbers only for
devices that claim to be on a multi-domain system. The check
for this is broken on powerpc, because the buid value is
truncated to 32 bits.

There is at least one machine (IBM QS21) that only uses
the high-order bits of the buid, so the return value
of pci_proc_domain() ends up being always zero, which
makes /proc/bus/pci useless.

Change the logic to always return '1' for a nonzero
buid value.

fabca2c0a4 [POWERPC] Add CHECK_FULL_REGS in several places in ptrace code
This restores the CHECK_FULL_REGS sanity check to every place that can
access the nonvolatile GPRs for ptrace.  This is already done for
native-bitwidth PTRACE_PEEKUSR, but was omitted for many other cases
(32-bit ptrace, PTRACE_GETREGS, etc.); I think there may have been more
uniform checks before that were lost in the recent cleanup of GETREGS et al.
