Jochen Friedrich 22f19daff4 [POWERPC] 8xx: Remove unused m8xx_cpm_hostalloc/free/dump()
m8xx_cpm_hostalloc is still defined in commproc.c, but no users are left
in the kernel tree. m8xx_cpm_hostfree and m8xx_cpm_hostdump are only
defined in the headers. Remove this dead code.

Paul Gortmaker 6c538111e3 [POWERPC] 83xx: Add device tree source for Wind River SBC834x board.
This adds the device tree source for the Wind River SBC834x board.
It is based on the MPC834x_MDS DTS, with the biggest difference being
the lack of BCSR and the PCI2 that the MDS gets via the PIB. That,
and this file is also dts-v1 format.

Paul Mackerras c847c853a5 PPC: Fix powerpc vio_find_name to not use devices_subsys
This fixes vio_find_name() in arch/powerpc/kernel/vio.c, which is
currently broken because it tries to use devices_subsys.  That is bad
for two reasons: (1) it's doing (or trying to do) a scan of all
devices when it should only be scanning those on the vio bus, and
(2) devices_subsys was an internal symbol of the device system code
which was never meant for external use and has now gone away, and
thus the kernel fails to compile on pSeries.

The new version uses bus_find_device_by_name() on the vio bus
(vio_bus_type).

Grant Likely 94d2dde738 [POWERPC] Efika: prune fixups and make them more carefull
Prune back Efika fixups to only include changes that are actually required
to get a working system.  Most of the drivers can accept the compatible
properties, even if they don't match the what is recommented in the generic
names recommended practice document.

This patch also adds extra checks so that fixups are not performed blindly.
Instead, the code first verifies that the device tree is faulty before
making any changes.  This way, if the Efika firmware is updated to fix
these issues, then the fixups will no longer get applied.

At this point; here is the list of fixups needed for the efika:
1. If the device_type property on the root node is 'chrp', then Linux won't
   boot.  Change device_type to 'efika' to avoid this condition
2. Add full interrupt list to the bestcomm node.  In actual fact, the
   bestcomm interrupts property is technically correct, it just doesn't
   expose the same granularity as the device driver expects.  All other
   5200 device trees provide a separate irq number for each bestcomm
   channel.  Rather than hack the driver, it's simpler to fix it up
3. /builtin/sound node is missing an interrupts property
4. /builtin/ethernet node is missing a phy-handle property and the
   device driver doesn't know what to do without one.

Paul Mackerras 55852bed57 Revert "[POWERPC] Fake NUMA emulation for PowerPC"
This reverts commit 5c3f5892a2,
basically because it changes behaviour even when no fake NUMA
information is specified on the kernel command line.

Firstly, it changes the nid, thus destroying the real NUMA
information.  Secondly, it also changes behaviour in that if a node
ends up with no memory in it because of the memory limit, we used to
set it online and now we don't.

Also, in the non-NUMA case with no fake NUMA information, we do
node_set_online once for each LMB now, whereas previously we only did
it once.  I don't know if that is actually a problem, but it does seem
unnecessary.

Replace all lock_cpu_hotplug/unlock_cpu_hotplug from the kernel and use
get_online_cpus and put_online_cpus instead as it highlights the

The new API guarantees protection against the cpu-hotplug operation, but
it doesn't guarantee serialized access to any of the local data
structures. Hence the changes needs to be reviewed.

In case of pseries_add_processor/pseries_remove_processor, use
cpu_maps_update_begin()/cpu_maps_update_done() as we're modifying the
cpu_present_map there.

David Gibson 22258fa40e [POWERPC] Enable RTC for Ebony and Walnut (v2)
This patch extends the Ebony and Walnut platform code to instantiate
the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip
found on both those boards.  The patch uses a helper function to scan
the device tree and instantiate the appropriate platform_device based
on it, so it should be easy to extend for other boards which have mmio
mapped RTC chips.

Along with this, the device tree binding for the ds1743 chips is
tweaked, based on the existing DS1385 OF binding found at:
	http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt
Although that document covers the NVRAM portion of the chip, whereas
here we're interested in the RTC portion, so it's not entirely clear
if that's a good model.

This implements only RTC class driver support - that is /dev/rtc0, not
/dev/rtc, and the low-level get/set time callbacks remain
unimplemented.  That means in order to get at the clock you will
either need a modified version of hwclock which will look at
/dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.

Geert Uytterhoeven b4cb2941f8 [POWERPC] PS3: Use the HVs storage device notification mechanism properly
The PS3 hypervisor has a storage device notification mechanism to wait
until a storage device is ready.  Unfortunately the storage device
probing code used this mechanism in an incorrect way, needing a
polling loop and handling of devices that are not yet ready.

This change corrects this by:
  - First waiting for the reception of an asynchronous notification
    that a new storage device became ready,
  - Then looking up the storage device in the device repository.

On shutdown, the storage probe thread is stopped and the storage
notification device is closed using a reboot notifier.

Michael Neuling 496b010e1e [POWERPC] kdump shutdown hook support
This adds hooks into the default_machine_crash_shutdown so drivers can
register a function to be run in the first kernel before we hand off
to the second kernel.  This should only be used in exceptional
circumstances, like where the device can't be reset in the second
kernel alone (as is the case with eHEA).  To emphasize this, the
number of handles allowed to be registered is currently #def to 1.

This uses the setjmp/longjmp code around the call out to the
registered hooks, so any bogus exceptions we encounter will hopefully
be recoverable.

Tested with bogus data and instruction exceptions.

Olof Johansson e057d985fd [POWERPC] Make smp_send_stop() handle panic and xmon reboot
smp_send_stop() will send an IPI to all other cpus to shut them down.
However, for the case of xmon-based reboots (as well as potentially some
panics), the other cpus are (or might be) spinning with interrupts off,
and won't take the IPI.

Current code will drop us into the debugger when the IPI fails, which
means we're in an infinite loop that we can't get out of without an
external reset of some sort.

Instead, make the smp_send_stop() IPI call path just print the warning
about being unable to send IPIs, but make it return so the rest of the
shutdown sequence can continue. It's not perfect, but the lesser of
two evils.

Also move the call_lock handling outside of smp_call_function_map so we
can avoid deadlocks in smp_send_stop().
