The xics code does update the default server information when the boot
cpu is removed. This patch recognizes when the boot cpu is being
removed and updates the appropriate information based on the new 'boot
cpu'.
Failure to update this information can causes us to leave irqs pinned
to cpus that are being removed, especially when removing the boot cpu.
The cpu is removed from the kernel, but cpu dlpar remove operations
fail since we cannot return the cpu to the hypervisor.

This splits off the kexec path bits of the xics_teardown_cpu() routine
into its own xics_kexec_teardown_cpu() routine. With the previous
combined routine the CPPR for a cpu that is being removed may have its
CPPR reset in the plpar_eoi() call (which explicitly sets the CPPR to
a non-zero value). Splitting of the kexec bits of the code prevents
this from happening in the cpu remove path.
Once again, this does not cause the cpu remove from the kernel to
fail, but it does cause cpu dlpar operations to not be able to return
the cpu to the hypervisor.

The affinity mask in the virq descriptor needs to be set before we
reset the affinity for the virq. Without doing this the call to get
the new irq server fails and we end up leaving the virq pinned to the
cpu we are removing.
This does not fail the cpu remove from the kernel, but it does prevent
cpu dlpar remove operations from returning the cpu to the hypervisor.

Currently, the kernel uses CONFIG_DEVICE_TREE to wrap a kernel image
with a fdt blob which means for any given configuration only one dts
file can be selected and so support for only one board can be built
This moves the selection of the default .dts file out of the kernel
config and into the bootwrapper makefile. The makefile chooses which
images to build based on the kernel config and the dts source file
name is taken directly from the image name. For example "cuImage.ebony"
will use "ebony.dts" as the device tree source file.
In addition, this patch allows a specific image to be requested from the
command line by adding "cuImage.%" and "treeImage.%" targets to the list
of valid built targets in arch/powerpc/Makefile. This allows the default
dts selection to be overridden.
Another advantage to this change is it allows a single defconfig to be
supplied for all boards using the same chip family and only differing in
the device tree.
Important note: This patch adds two new zImage targets; zImage.dtb.% and
zImage.dtb.initrd.% for zImages with embedded dtb files. Currently
there are 5 platforms which require this: ps3, ep405, mpc885ads, ep88xc,
adder875-redboot and ep8248e. This patch *changes the zImage filenames*
for those platforms. ie. 'zImage.ps3' is now 'zImage.dtb.ps3'.
This new zImage.dtb targets were added so that the .dts file could be
part of the dependancies list for building them.

Here's a dumb simple implementation of fake NUMA nodes for PowerPC.
Fake NUMA nodes can be specified using the following command line
option
numa=fake=<node range>
node range is of the format <range1>,<range2>,...<rangeN>
Each of the rangeX parameters is passed using memparse(). I find the
patch useful for fake NUMA emulation on my simple PowerPC machine.
I've tested it on a numa box with the following arguments
numa=fake=512M
numa=fake=512M,768M
numa=fake=256M,512M mem=512M
numa=fake=1G mem=768M
numa=fake=
without any numa= argument
The other side-effect introduced by this patch is that; in the case
where we don't have NUMA information, we now set a node online after
adding each LMB. This node could very well be node 0, but in the case
that we enable fake NUMA nodes, when we cross node boundaries, we need
to set the new node online.

Looks like "[POWERPC] kdump shutdown hook support" broke builds when

Move the debugger hooks to under CONFIG_DEBUGGER || CONFIG_KEXEC, since
that's when the crash code is enabled.

This change broke recovery of exceptions in iret:
commit 72fe4858544292ad64600765cb78bc02298c6b1c
Author: Glauber de Oliveira Costa <gcosta@redhat.com>
x86: replace privileged instructions with paravirt macros
The ENTRY(native_iret) macro adds alignment padding before the iretq
instruction, so "iret_label" no longer points exactly at the instruction.
It was sloppy to leave the old "iret_label" label behind when replacing
its nearby use. Removing it would have revealed the other use of the
label later in the file, and upon noticing that use, anyone exercising
the minimum of attention to detail expected of anyone touching this
subtle code would realize it needed to change as well.

On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from
the LCD controller. It's controlled by "contrast" registers though.
This patch lets boards declare that they have that kind of backlight
control. The driver can then export this control, letting screenblank and
other operations actually take effect ... reducing the typically
substantial power drain from the backlight.
Note that it's not fully cooked
- doesn't force backlight off during system suspend
- the "power" and "blank" events may not be done right
This should be easily added in the future.

NR_OPEN (historically set to 1024*1024) actually forbids processes to open
more than 1024*1024 handles.
Unfortunatly some production servers hit the not so 'ridiculously high
value' of 1024*1024 file descriptors per process.
Changing NR_OPEN is not considered safe because of vmalloc space potential
exhaust.
This patch introduces a new sysctl (/proc/sys/fs/nr_open) wich defaults to
1024*1024, so that admins can decide to change this limit if their workload
needs it.

- All implementations can be __devinit
- The function prototypes were in asm/timex.h but they all must be the same,
so create a single declaration in linux/timex.h.
- uninline the sparc64 version to match the other architectures
- Don't bother #defining ARCH_HAS_READ_CURRENT_TIMER to a particular value.

When passing a zero address to kallsyms_lookup(), the kernel thought it was
a valid kernel address, even if it is not. This is because is_ksym_addr()
called is_kernel_extratext() and checked against labels that don't exist on
many archs (which default as zero). Since PPC was the only kernel which
defines _extra_text, (in 2005), and no longer needs it, this patch removes
_extra_text support.
