340ffd267c [POWERPC] 4xx: 440EPx/GRx incorrect write to DDR SDRAM errata workaround
Add a workaround for PowerPC 440EPx/GRx incorrect write to
DDR SDRAM errata. Data can be written to wrong address
in SDRAM when write pipelining enabled on plb0. We disable
it in the cpu_setup for these processors at early init.

8112753bb2 [POWERPC] 4xx: Move 440EP(x) FPU setup from head_44x to cpu_setup_4xx
The PowerPC 440EP(x) FPU init is currently done in head_44x
under ifdefs. Since we should support more then one board
in the same kernel, we move FPU initialization code from head_44x
to cpu_setup_44x and add cpu_setup callbacks for 440EP(x).

84e3ad5b91 [POWERPC] 4xx: Introduce cpu_setup functionality to 44x platform
This adds cpu_setup functionality for ppc44x platform.
Low level cpu-spefic initialization routines should be
placed in cpu_setup_44x.S and a callback should be
added to cputable. The cpu_setup is invoked
by identify_cpu() function at early init.

d831d0b83f [POWERPC] Implement clockevents driver for powerpc
This registers a clock event structure for the decrementer and turns
on CONFIG_GENERIC_CLOCKEVENTS, which means that we now don't need
most of timer_interrupt(), since the work is done in generic code.
For secondary CPUs, their decrementer clockevent is registered when
the CPU comes up (the generic code automatically removes the
clockevent when the CPU goes down).

a0c7ce9c87 [POWERPC] Fix panic in RTAS code
Some older pSeries machines were panicking in pSeries_log_error
because it was getting called before it was ready.  This is a result
of commit "[POWERPC] pseries: Fix jumbled no_logging flag."
(79c0108d1b).

This fixes it by explicitly enabling RTAS error logging when it has
been initialized, and also makes the code clearer by renaming the
"no_more_logging" variable to "logging_enabled".

/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.

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.

It turns out we are passing a real and not a virtual irq into
get_irq_server.  This works for the case where hwirq < NR_IRQS and we
set virq = hwirq.  In my case however hwirq = 590082 and we try and

39db0fd9db [POWERPC] Fix mpc834x USB-MPH configuration.
mpc834x USB-MPH configuration got broken by commit
6f44256002. The selection bits in SICRL
should be cleared rather than set to configure the USB MUXes for the MPH.

83af919e0f [POWERPC] Fix copy'n'paste typo in commproc.c
The powerpc version of commproc.c exports cpm_dpram_addr twice
and cpm_dpram_phys not at all due to a typo. This patch fixes this
problem.

603c461250 [POWERPC] spufs: fix mismerge, making context signal{1,2} files readable again
The commit 8b6f50ef1d seems to have
been affected by a mismerge of a duplicate patch
(d054b36ffd) - both the
spufs_dir_contents and spufs_dir_nosched_contents have been given
write-only signal notification files.

This change reverts the spufs_dir_contents array to use the
readable signal notification file implementation.
