Matthew Wilcox 27663c5855 ACPI: Change acpi_evaluate_integer to support 64-bit on 32-bit kernels
As of version 2.0, ACPI can return 64-bit integers.  The current
acpi_evaluate_integer only supports 64-bit integers on 64-bit platforms.
Change the argument to take a pointer to an acpi_integer so we support
64-bit integers on all platforms.

lenb: replaced use of "acpi_integer" with "unsigned long long"
lenb: fixed bug in acpi_thermal_trips_update()

Tony Luck 7f30491ccd [IA64] Move include/asm-ia64 to arch/ia64/include/asm
After moving the the include files there were a few clean-ups:

1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h>

2) Some comments alerted maintainers to look at various header files to
make matching updates if certain code were to be changed. Updated these
comments to use the new include paths.

3) Some header files mentioned their own names in initial comments. Just
deleted these self references.

Franck Bui-Huu 82524746c2 rcu: split list.h and move rcu-protected lists into rculist.h
Move rcu-protected lists from list.h into a new header file rculist.h.

This is done because list are a very used primitive structure all over the
kernel and it's currently impossible to include other header files in this
list.h without creating some circular dependencies.

For example, list.h implements rcu-protected list and uses rcu_dereference()
without including rcupdate.h.  It actually compiles because users of
rcu_dereference() are macros.  Others RCU functions could be used too but
aren't probably because of this.

Therefore this patch creates rculist.h which includes rcupdates without to
many changes/troubles.

Jeff Garzik 9010eff0ea [IA64] minor irq handler cleanups
- remove unused 'irq' argument from pfm_do_interrupt_handler()

- remove pointless cast to void*

- add KERN_xxx prefix to printk()

- remove braces around singleton C statement

- in tioce_provider.c, start tioce_dma_consistent() and
  tioce_error_intr_handler() function declarations in column 0

This change's main purpose is to prepare for the patchset in
jgarzik/misc-2.6.git#irq-remove, that explores removal of the
never-used 'irq' argument in each interrupt handler.

Russ Anderson 64135fa97c [IA64] Fix Altix BTE error return status
The Altix shub2 BTE error detail bits are in a different location
than on shub1.  The current code does not take this into account
resulting in all shub2 BTE failures mapping to "unknown".

This patch reads the error detail bits from the proper location,
so the correct BTE failure reason is returned for both shub1
and shub2.

Dean Nelson 4c013f5c7e [IA64] XPC heartbeat timer function must run on CPU 0
Currently, XPC's heartbeat timer function runs on whatever CPU modprobe/insmod
ran on when XPC was started. To avoid the heartbeat from being delayed for
long periods the timer function must run on CPU 0.

N.B. Altix doesn't currently allow cpu0 to be taken offline, so this is
safe for now.  This code must be revised when offline of cpu0 is enabled.

Russ Anderson 1f3b6045f7 [IA64] Disable/re-enable CPE interrupts on Altix
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.
