The ps3 target produces two images, and the binary one is not the
"primary" image that corresponds to the -o flag; thus, it no longer
uses the generic binary flag.
On platforms which do use the binary flag, it no longer produces a
.bin suffix, so that the output file matches what was passed to the -o flag.
This should fix the zImage ln problems for the ps3 target.

There are plans afoot to use pci_restore_msi_state() to restore MSI
state after a device reset. In order for this to work for the RTAS MSI
backend, we need to read back the MSI message from config space after
it has been setup by firmware.
This should be sufficient for restoring the MSI state after a device
reset, however we will need to revisit this for suspend to disk if that
is ever implemented on pseries.

The ST40 stuff in-tree hasn't built for some time, and hasn't been
updated for over 3 years. ST maintains their own out-of-tree changes
and rebases occasionally, and that's ultimately where all of the ST40
users go anyways.
In order for the ST40 code to be brought up to date most of the stuff
removed in this changeset would have to be rewritten anyways, so there's
very little benefit in keeping the remnants around either.

When the CPE handler encounters too many CPEs (such as a solid single
bit memory error), it sets up a polling timer and disables the CPE
interrupt (to avoid excessive overhead logging the stream of single
bit errors). disable_irq_nosync() calls chip->disable() to provide
a chipset specifiec interface for disabling the interrupt. This patch
adds the Altix specific support to disable and re-enable the CPE interrupt.

There is a section mismatch when building CONFIG_FLATMEM=y kernels
that also have CONFIG_HOTPLUG_CPU=y
WARNING: vmlinux.o(.text+0x5a902): Section mismatch: reference to \
.init.text:__alloc_bootmem (between 'per_cpu_init' and 'count_pages')
The issue occurs because per_cpu_init() in mm/contig.c is
marked __cpuinit (which is #define'd to nothing on a hot
plug cpu configuration) call __alloc_bootmem() (which is
an __init function). The usage is actually safe because
the __alloc_bootmem() is inside an "if (first_time)" test
so that the call is only made while it is still legal to
do so.
But the warning is irritating. Move the allocation to
find_memory().

"[S390] Add per-cpu idle time / idle count sysfs attributes" causes

Fix this by adding some #ifdef's. Real fix would be to cleanup the

be quite a big patch. For the time being this is good enough.
