This modifies <asm-ia64/types.h> to use the <asm-generic/int-*.h>
generic include files.

* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6:
  [IA64] fix file and descriptor handling in perfmon
  [IA64] TS_RESTORE_SIGMASK
  [IA64] smp.c coding style fix
  [IA64] fix section mismatch in arch/ia64/kernel/topology.c
  [IA64] fix section mismatch in arch/ia64/kernel/palinfo.c
  [IA64] fix section mismatch in arch/ia64/kernel/irq.c
  [IA64] fix section mismatch in arch/ia64/kernel/acpi.c

Replace TIF_RESTORE_SIGMASK with TS_RESTORE_SIGMASK and define
our own set_restore_sigmask() function.  This saves the costly
SMP-safe set_bit operation, which we do not need for the sigmask
flag since TIF_SIGPENDING always has to be set too.

The declaration of dmi helper functions is a bit messy and inconsistent at the
moment:

* On ia64 they are declared in <asm/io.h>.
* On x86-64 they are declared in <asm/dmi.h>.
* On i386 they are declared both in <asm/io.h> and <asm/dmi.h>.

Fix the header files so that the dmi helper functions are consistently
defined in <asm/dmi.h>.

This patch silences:

	WARNING: vmlinux.o(.text+0x44672): Section mismatch in
	reference from the function arch_register_cpu() to the
	function .cpuinit.text:register_cpu()

Changes are based on codes in arch/x86/kernel/topology.c

Lots of asm-*/futex.h call pagefault_enable and pagefault_disable, which
are declared in linux/uaccess.h, without including linux/uaccess.h.

They all include asm/uaccess.h, so this patch replaces asm/uaccess.h
with linux/uaccess.h.

TIF_RESTORE_SIGMASK no longer needs to be in the _TIF_WORK_* masks.
Those low bits are scarce.  Renumber TIF_RESTORE_SIGMASK to free one up.

Legacy HP ia64 platforms currently cannot provide
/proc/cpuinfo/physical_id due to legacy SAL/PAL implementations.
However, that physical topology information can be obtained
via ACPI.

Provide an interface that gives ACPI one last chance to provide
physical_id for these legacy platforms. This logic only comes
into play iff:

- ACPI actually provides slot information for the CPU
- we lack a valid socket_id

Otherwise, we don't do anything.

Since x86 uses the ACPI processor driver as well, we provide a nop
stub function for arch_fix_phys_package_id() in asm-x86/topology.h
