Pull "Disintegrate and delete asm/system.h" from David Howells:
 "Here are a bunch of patches to disintegrate asm/system.h into a set of
  separate bits to relieve the problem of circular inclusion
  dependencies.

  I've built all the working defconfigs from all the arches that I can
  and made sure that they don't break.

  The reason for these patches is that I recently encountered a circular
  dependency problem that came about when I produced some patches to
  optimise get_order() by rewriting it to use ilog2().

  This uses bitops - and on the SH arch asm/bitops.h drags in
  asm-generic/get_order.h by a circuituous route involving asm/system.h.

  The main difficulty seems to be asm/system.h.  It holds a number of
  low level bits with no/few dependencies that are commonly used (eg.
  memory barriers) and a number of bits with more dependencies that
  aren't used in many places (eg.  switch_to()).

  These patches break asm/system.h up into the following core pieces:

    (1) asm/barrier.h

        Move memory barriers here.  This already done for MIPS and Alpha.

    (2) asm/switch_to.h

        Move switch_to() and related stuff here.

    (3) asm/exec.h

        Move arch_align_stack() here.  Other process execution related bits
        could perhaps go here from asm/processor.h.

    (4) asm/cmpxchg.h

        Move xchg() and cmpxchg() here as they're full word atomic ops and
        frequently used by atomic_xchg() and atomic_cmpxchg().

    (5) asm/bug.h

        Move die() and related bits.

    (6) asm/auxvec.h

        Move AT_VECTOR_SIZE_ARCH here.

  Other arch headers are created as needed on a per-arch basis."

Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that.  We'll find out anything that got broken and fix it..

Pull miscellaneous Itanium patches from Tony Luck.

The conflicts in arch/ia64/hp/sim/simserial.c were due to patches to
simserial that had alredy been included (with lots of further cleanups)
in the serial tree.

[IA64] Check return from device_register() in cx_device_register()

2012-02-27T21:01:42+00:00

The device_register() is declared with must_check, causing this:

arch/ia64/sn/kernel/tiocx.c: In function 'cx_device_register':
arch/ia64/sn/kernel/tiocx.c:210:17: warning: ignoring return value of 'device_register', declared with attribute warn_unused_result

Check the return value, and free resources if it fails.

ia64/PCI: SN: convert to pci_scan_root_bus() for correct root bus resources

2012-02-24T03:19:01+00:00

Convert from pci_scan_bus() to pci_scan_root_bus().  Supply the root
bus resources from bussoft.  When we move the resource adjustment from
pcibios_fixup_resources() to the PCI core, it will be important to have
the root bus resources correct from the beginning.
