Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system

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..

Ferenc Wagner 8af3d8d5bc [SCSI] fusion: ensure NUL-termination of MptCallbacksName elements
Using strlcpy instead of memcpy makes the strlen() calls superfluous
and also ensures zero-termination of the copied string.
At the same time get rid of the magic constant 50.

Actually, I can't see why copying the callback name is necessary
instead of simply storing a pointer to it (just like to the callback
function itself), but that goes beyond the scope of this fix.

kashyap.desai@lsi.com 98cbe371fd [SCSI] mptfusion: Fix for device offline while doing aggressive HBA reset
[Resend patch as per Bernd Schubert comment ]

Issue:

Device goes offline while doing aggressive HBA reset
along with IO using some utility.

Root cause:

FW goes into bad state due to aggressive reset. Softreset does not
help to recover FW. And also aggressive reset open up the window for
Error handling thread to kicked off at the same time HBA will be in
constant RESET loop as part of aggressive reset test case can lead
Device to goes offline.

Changes:

1. Added extra check as below inside eh_timed_out call back as below.
   if(ioc->ioc_reset_in_progress) Rc = EH_TIMER_RESET

2. Removed " DOORBELL_ACTIVE" check for SAS controller from task
   management context.  Since SAS controller uses high priority queue
   for task management. This check is not required for SAS controller.

3. Moved SoftReset call to HardReset from Task Mgmt context.

Joe Perches 85ee7a1d39 treewide: cleanup continuations and remove logging message whitespace
Using C line continuation inside format strings is error prone.
Clean up the unintended whitespace introduced by misuse of \.
Neaten correctly used line continations as well for consistency.

drivers/scsi/arcmsr/arcmsr_hba.c has these errors as well,
but arcmsr needs a lot more work and the driver should likely be
moved to staging instead.

Tejun Heo 9fd097b149 block: unexport DISK_EVENT_MEDIA_CHANGE for legacy/fringe drivers
In-kernel disk event polling doesn't matter for legacy/fringe drivers
and may lead to infinite event loop if ->check_events() implementation
generates events on level condition instead of edge.

Now that block layer supports suppressing exporting unlisted events,
simply leaving disk->events cleared allows these drivers to keep the
internal revalidation behavior intact while avoiding weird
interactions with userland event handler.

Kashyap, Desai bcfe42e980 [SCSI] mptfusion: Fix Incorrect return value in mptscsih_dev_reset
There's a branch at the end of this function that
is supposed to normalize the return value with what
the mid-layer expects. In this one case, we get it wrong.

Also increase the verbosity of the INFO level printk
at the end of mptscsih_abort to include the actual return value
and the scmd->serial_number. The reason being success
or failure is actually determined by the state of
the internal tag list when a TMF is issued, and not the
return value of the TMF cmd. The serial_number is also
used in this decision, thus it's useful to know for debugging
purposes.
