[IA64] Fix spinaphore down_spin()

Typo in down_spin() meant it only read the low 32 bits of the
"serve" value, instead of the full 64 bits. This results in the
system hanging when the values in ticket/serve get larger than
32-bits. A big enough system running the right test can hit this
in a just a few hours.
Broken since 883a3acf5b0d4782ac35981227a0d094e8b44850

This patch uses "ENABLE_ON_INIT" flag on the emif clock nodes
to avoid the emif clk getting cut as part of reset un-used clock
routine which prevents boot.
Since "omap4xxx_clk_init()" calls "clk_enable_init_clocks()"
which increases the usecount on all ENABLE_ON_INIT clocks, it
prevents "omap2_clk_disable_unused()" from disabling the clock.
The real fix is to have driver for EMIF and do clock get/enable
as part of it. The EMIF driver is planned to be done HWMOD way
so till that available to keep omap3_defconfig booting on OMAP4430,
this patch is necessary.
(Will updated the auto-gen script for 44xx accordingly)
The fix was suggested by Paul Walmsley

Checking to se if the IO daisy chain is enabled should be checking the
PM_WKEN register, not the PM_WKST register. Reading PM_WKST tells us
if an event occurred, not whether or not it is enabled.
Apparently, we've been lucky until now in that a pending event has not
been there during enable. However, on 3630/Zoom3, I noticed because
of the WARN that this timeout was always happening.

The addition of the new debounce code (commit
168ef3d9a56bd8bffe0ef4189c450888b4aefefe) broke the auto-disable of
debounce clocks on idle by forgetting to update the debounce clock
enable mask.
Add back the updating of bank->dbck_enable_mask so debounce clocks are
auto-disabled.

The kernel timer queue is being run currently from a GP timer running in a one
shot mode, which works in a way that when it expires, it will also stop.
Usually during this situation, the interrupt handler will ack the interrupt,
load a new value to the timer and start it again. During suspend, the
situation is slightly different, as we disable interrupts just before
timekeeping is suspended, which leaves a small window where the timer can
expire before it is stopped, and will leave the interrupt flag pending.
This pending interrupt will prevent ARM sleep entry, thus now we ack it always
when we are attempting to stop a timer.

When I introduced the global variable gsi_end I thought gsi_end on
io_apics was one past the end of the gsi range for the io_apic. After
it was pointed out the the range on io_apics was inclusive I changed
my global variable to match. That was a big mistake. Inclusive
semantics without a range start cannot describe the case when no gsi's
are allocated. Describing the case where no gsi's are allocated is
important in sfi.c and mpparse.c so that we can assign gsi numbers
instead of blindly copying the gsi assignments the BIOS has done as we
do in the acpi case.
To keep from getting the global variable confused with the gsi range
end rename it gsi_top.
To allow describing the case where no gsi's are allocated have gsi_top
be one place the highest gsi number seen in the system.
This fixes an off by one bug in sfi.c:

pcibios_fixup_device_resources() presently skips over resources flagged
with IORESOURCE_PCI_FIXED, which is a remnant of the old PCI-auto code.
The only user for this at present is the Dreamast GAPSPCI code which
can't tolerate any adjustments to the BARs, but a combination of the
IORESOURCE_PCI_FIXED and zeroed out hose offsets does the right thing for
this case already, so we simply kill off the special casing.

When going to standby mode mpc code maps the whole soc5200 node
to access warious MBAR registers. However as of_iomap uses 'reg'
property of device node, only small part of MBAR is getting mapped.
Thus pm code gets oops when trying to access high parts of MBAR.
As a way to overcome this, make mpc52xx_pm_prepare() explicitly
map whole MBAR (0xc0000).

This patch probes for the Super IO chip and reserves the IO range when
found. It avoids enabling the IDE interface on the Avanti family, since
none has IDE. It enables the Enhanced Parallel Port v1.9 feature.

mpic_resume() on G5 macs blindly dereferences mpic->fixups, but
it may legitimately be NULL (as on PowerMac7,2). Add an explicit
check.
This fixes suspend-to-disk with one processor (maxcpus=1) for me.

When trying to flash a machine via the update_flash command, Anton received the
following error:
Restarting system.
FLASH: kernel bug...flash list header addr above 4GB
The code in question has a comment that the flash list should be in
the kernel data and therefore under 4GB:
/* NOTE: the "first" block list is a global var with no data
* blocks in the kernel data segment. We do this because
* we want to ensure this block_list addr is under 4GB.
*/
Unfortunately the Kconfig option is marked tristate which means the variable
may not be in the kernel data and could be above 4GB.
Instead of relying on the data segment being below 4GB, use the static
data buffer allocated by the kernel for use by rtas. Since we don't
use the header struct directly anymore, convert it to a simple pointer.

Irq stacks provide an essential protection from stack overflows through
external interrupts, at the cost of two additionals stacks per CPU.
Enable them unconditionally to simplify the kernel build and prevent
people from accidentally disabling them.

kexec_perpare_cpus_wait() iterates i through NR_CPUS to check
paca[i].kexec_state of each to make sure they have quiesced.
However now we have dynamic PACA allocation, paca[NR_CPUS] is not necessarily
valid and we overrun the array; spurious "cpu is not possible, ignoring"
errors result. This patch iterates for_each_online_cpu so stays
within the bounds of paca[] -- and every CPU is now 'possible'.

We are seeing boot fails on some System p machines when using the kdump
crashkernel= boot option. The default kdump base address is 32MB, so if we
reserve 256MB for kdump then we reserve all of the RMO except the first 32MB.
We really want kdump to reserve some memory in the RMO and most of it
elsewhere but that will require more significant changes. For now we can shift
the default base address to 64MB when CONFIG_PPC64 and CONFIG_RELOCATABLE are
set. This isn't quite correct since what we really care about is the kdump
kernel is relocatable, but we already make the assumption that base kernel
and kdump kernel have the same CONFIG_RELOCATABLE setting, eg:
#ifndef CONFIG_RELOCATABLE
if (crashk_res.start != KDUMP_KERNELBASE)
printk("Crash kernel location must be 0x%x\n",
KDUMP_KERNELBASE);
...
RTAS is instantiated towards the top of our RMO, so if we were to go any
higher we risk not having enough RMO memory for the kdump kernel on boxes
with a 128MB RMO.
