8ac4ce742c ide: fix host drivers depending on ide_generic to probe for interfaces (take 2)
* Add mpc8xx_ide_probe() to mpc8xx.c and call it from probe_for_hwifs().

* Convert ide_arm, ide-cris, ide-h8300, ide-pnp, buddha, falconide, gayle,
  macide, q40ide, cmd640 and mpc8xx host drivers to use ide_device_add().

  This removes dependency on ide_generic for these drivers so update
  ide/Kconfig accordingly.

v2:
* ide_arm build fix (s/ide_device_idx/ide_device_add/)
  (Thanks to Christoph Lameter <clameter@sgi.com> for reporting the problem).

* Remove ide_init_port_data() call from ide_arm_init() and move
  ide_arm_init() call from init_ide_data() to ide_init().

This patch is a preparation for the future changes (and as a side-effect
makes obsolete "idex=io[,ctl[,irq]]" kernel parameters work for ide_arm).

cbb010c180 ide: drop 'initializing' argument from ide_register_hw()
* Rename init_hwif_data() to ide_init_port_data() and export it.

* For all users of ide_register_hw() with 'initializing' argument set
  hwif->present and hwif->hold are always zero so convert these host
  drivers to use ide_find_port()+ide_init_port_data()+ide_init_port_hw()
  instead (also no need for init_hwif_default() call since the setup
  done by it gets over-ridden by ide_init_port_hw() call).

* Drop 'initializing' argument from ide_register_hw().

b0d5bc27ce ide: Fix build break caused by "ide: remove ideprobe_init()"
Fix build break of powerpc holly_defconfig:

In file included from arch/powerpc/platforms/embedded6xx/holly.c:24:
include/linux/ide.h:1206: error: 'CONFIG_IDE_MAX_HWIFS' undeclared here (not in a function)

There's no need to have a sized array in the prototype, might as well
turn it into a pointer.

It could probably be argued that large parts of the include file can be
covered under #ifdef CONFIG_IDE, but that's a larger undertaking.

2e13093a83 ide: fix probing for hosts with serialized or IRQ sharing interfaces
After hwif_register_devices() IDE devices are ready to be used so
the way in which ide_device_add() works currently is racy for hosts
with serialized / IRQ sharing interfaces.

Fix ide_device_add() by looping over interfaces for probe_hwif(),
hwif_init() and hwif_register_devices() operations.

795d74b51a ide: don't try to unregister interfaces if 'initializing' in ide_register_hw()
Host drivers using ide_register_hw() and 'initializing == 1':

* ide-pnp
  - depends on ISA

* ide_arm 
  - ARM arch specific
  - initialized before all other host drivers

* ide-cris
  - CRIS arch specific => IDE_ARCH_OBSOLETE_INIT is not defined
  - broken

* ide-h8300
  - H8300 arch specific => IDE_ARCH_OBSOLETE_INIT is not defined, no PCI

* buddha/q40/gayle/macide/falconide
  - M68K arch specific => IDE_ARCH_OBSOLETE_INIT is not defined, no PCI

Since the only host drivers which probe interfaces before the above ones are:

* ali14xx/dtc2278/ht6560b/qd65xx/umc8672
  - depend on ISA
  - require IDE_ARCH_OBSOLETE_INIT=y to work

* PCI ones
  - depend on PCI

don't try to unregister interfaces if 'initializing == 1' in ide_register_hw()
(it is possible that built-in host drivers will claim all IDE interfaces but
later ide-pnp host driver will try to unregister them - this change fixes it).

Also skip hwif->hold check if 'initializing == 1' since it is set only by:

* pmac
  - PPC && PMAC specific => no ISA

* au1xxx-ide
  - MIPS && SOC_AU1200 specific => no ISA

and use ide_find_port() helper to find free ide_hwifs[] slot.

07a085ebd3 ide-cris: fix DMA methods
* Rename cris_dma_{on,off}() to cris_dma_host_{on,off}().

* Remove no longer needed ->dma_off_quietly
  (IDE core has the needed code now).

* Make cris_dma_host_on() void.

I left fixing ide-cris after "kill dma_on/dma_off_quietly() methods"
patch because:

* Currently this driver is broken: cris_dma_on() (returns 'int')
  is assigned to hwif->dma_host_on (returns 'void') so the driver
  won't build.

* ->ide_dma_on method was missing so the driver OOPS-es on attempt
  to enable DMA.

* drive->using_dma was never set/cleared so DMA wouldn't be used anyway.

Unfortunately it seems that ide-cris stays broken even after this patch:

* V10: <asm/arch-v10/ide.h> needs fixing
  - ide_init_default_hwifs() should be removed
    (IDE core no longer uses it)
  - same for ide_init_hwif_ports() and ide_default_{irq,io_base}()
    (they shouldn't be needed for ide-cris host driver)

* V32: I'm unable to find a place which defines ETRAX_ARCH_V32

but I'm leaving fixing this to CRIS gurus. :)

* drive->using_dma was never enabled since cs5520 host driver's

2fe5c1d7eb ocfs2: clean up bh null checks
If we know a buffer_head is non-null, then brelse() is unnecessary and
put_bh() can be used instead. Also, an explicit check for NULL is
unnecessary when using brelse(). This patch only covers buffer_head_io.c and
resize.c, which have recently added code which exhibits this problem.

2d4b1cbb44 ocfs2/dlm: Clear joining_node on hearbeat node down
Currently the process of dlm join contains 2 steps: query join and assert join.
After query join, the joined node will set its joining_node. So if the joining
node happens to panic before the 2nd step, the joined node will fail to clear
its joining_node flag because that node isn't in the domain map. It at least
cause 2 problems.
1. All the new join request will fail. So no new node can mount the volume.
2. The joined node can't umount the volume since during the umount process it
   has to wait for the joining_node to be unknown. So the umount will be hanged.

The solution is to clear the joining_node before we check the domain map.

Lots of people are having trouble with the default timeouts, which are too

ocfs2-users, as well as data from bug reports. This should reduce the amount

cf8e06f1a8 [PATCH 1/2] ocfs2: add flock lock type
This adds a new dlmglue lock type which is intended to back flock()
requests.

Since these locks are driven from userspace, usage rules are much more
liberal than the typical Ocfs2 internal cluster lock. As a result, we can't
make use of most dlmglue features - lock caching and lock level
optimizations in particular. Additionally, userspace is free to deadlock
itself, so we have to deal with that in the same way as the rest of the
kernel - by allowing a signal to abort a lock request.

In order to keep ocfs2_cluster_lock() complexity down, ocfs2_file_lock()
does it's own dlm coordination. We still use the same helper functions
though, so duplicated code is kept to a minimum.
