The UV chipset automatically supplies the upper bits on nodes

UV blades may not have any blade-local memory. Add a field
(nid) to the UV blade structure to indicates whether the node
has local memory. This is needed by the GRU driver (pushed

These patches extend struct platform device data for a bunch of
SuperH Mobile processors and embedded boards. The patches simply
add hardware block ids to on-chip platform devices. Platform
devices off chip (such as external ethernet controllers or flash
chips) are left out which gives them a special case hardware block
id of zero.
Upcoming Runtime PM code will make use of the hardware block id
to group devices together. The hardware block id can also be used
to extend the SuperH Mobile clock framework implementation.
This series of patches depend on the following:
"Driver Core: Add platform device arch data V3".
This patch adds a hwblk_id member to struct pdev_archdata. This member
should be used to point out on-chip hardware block id.

From Gabe Black in bugzilla 13888:
native_save_fl is implemented as follows:
11static inline unsigned long native_save_fl(void)
12{
13 unsigned long flags;
14
15 asm volatile("# __raw_save_flags\n\t"
16 "pushf ; pop %0"
17 : "=g" (flags)
18 : /* no input */
19 : "memory");
20
21 return flags;
22}
If gcc chooses to put flags on the stack, for instance because this is
inlined into a larger function with more register pressure, the offset
of the flags variable from the stack pointer will change when the
pushf is performed. gcc doesn't attempt to understand that fact, and
address used for pop will still be the same. It will write to
somewhere near flags on the stack but not actually into it and
overwrite some other value.
I saw this happen in the ide_device_add_all function when running in a
simulator I work on. I'm assuming that some quirk of how the simulated
hardware is set up caused the code path this is on to be executed when
it normally wouldn't.
A simple fix might be to change "=g" to "=r".

The latest Apple MacBook (MacBook5,2) doesn't reboot successfully
under Linux; neither the EFI reboot method nor the default method
using the keyboard controller works (the system just hangs and doesn't
reset). However, the method using the "PCI reset register" at 0xcf9
does work.
This adds a quirk to detect this machine via DMI and force the
reboot_type to BOOT_CF9. With this it reboots successfully without
requiring a command-line option. Note that the EFI code forces
reboot_type to BOOT_EFI when the machine is booted via EFI, but this
overrides that since the core_initcall runs after the EFI
initialization code.

The code was incorrectly reserving memtypes using the page
virtual address instead of the physical address. Furthermore,
the code was not ignoring highmem pages as it ought to.
( upstream does not pass in highmem pages yet - but upcoming
graphics code will do it and there's no reason to not handle
this properly in the CPA APIs.)

In mm/slab.c the function do_ccupdate_local requires that interrupts be
disabled. If they are not, we panic with CONFIG_DEBUG_SLAB.
So we disable interrupts while processing IPIs. Also these are not shared
irqs, so get rid of the IRQF_SHARED flag.

The current interrupt handling code for the MSP4200 always masks an
interrupt before acknowledging it. This is not required, as that will be
handled by the level interrupt handler. This change simplifies the MSP4200
code to remove the masking in the ack routine, and makes sure that the
minimum required operation is performed for masking and acking, rather
than always both masking and acking the interrupt.
