According to the PCI Express specification, we must wait for at least
1 second after turning power off before taking any action that relies
on power having been removed from the slot/adapter. For this, current
pciehp wait for 1 second after issuing the power off command in
hpc_power_off_slot() function. But waiting for 1 second in
hpc_power_off_slot() can make pciehp probing slow-down because pciehp
probe code calls hpc_power_off_slot() if the slot is not occupied just
in case. We don't need to wait for 1 second at the pciehp probe time
because there is no action on that empty slot. So move 1 second wait
from hpc_power_off_slot() to the caller of hpc_power_off_slot().

Fix improper long wait for command completion in pciehp probing.
As described in PCI Express specification, software notification is
not generated if the command that occurs as a result of a write to the
Slot Control register that disables software notification of command
completed events. Since pciehp driver doesn't take it into account,
such command is issued in pciehp probing, and it causes improper long
wait for command completion.
This patch changes the pciehp driver to take such command into
account.

Fix the "pciehp probing slow" problem reported from Jan C. Nordholz in
http://bugzilla.kernel.org/show_bug.cgi?id=10751.
The command completed bit in Slot Status register applies only to
commands issued to control the attention indicator, power indicator,
power controller, or electromechanical interlock. However, writes to
other parts of the Slot Control register would end up writing to the
control fields. Hence, any write to Slot Control register is
considered as a command. However, if the controller doesn't support
any of attention indicator, power indicator, power controller and
electromechanical interlock, command completed bit would not set in
writing to Slot Control register. In this case, we should not wait for
command completed bit set, otherwise all commands would be considered
not completed in timeout seconds (1 sec.).
The cause of the problem is pciehp driver didn't take this situation
into account. This patch changes pciehp to take it into account. This
patch also add the check for "No Command Completed Support" bit in
Slot Capability register. If it is set, we should not wait for command
completed bit set as well.
This problem seems to be revealed by the commit
c27fb883df that fixed the bug that
pciehp did not wait for command completed properly (pciehp just
ignored the command completion event).

In 2.6.25, ramdisk devices show up in /proc/partitions, which is a
behaviour change from the old rd.c. Add GENHD_FL_SUPPRESS_PARTITION_INFO,
which was present in rd.c.
All kernels prior to 2.6.25 weren't displaying ramdisks in
/proc/partitions. Since there are many userspace tools using information
from /proc/partitions some of them may now behave incorrectly (I didn't
tested any though). For example before 2.6.25 /proc/partitions was empty
if no block devices like hard disks and such were detected by kernel. Now
all 16 ramdisks are always visible there. Some software may rely on such
information (I mean, on empty /proc/partitions).
There was quite similar situation back in 2004, and ramdisks were excluded
back from displaying. Thats why I called this a regression (maybe a bit
unfortunate). See this patch for info:
http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.3-rc2/2.6.3-rc2-mm1/broken-out/nbd-proc-partitions-fix.patch
I also think that someone somewhere (long time ago) excluded ramdisks from
/proc/partitions for good reasons. It is possible that now such new
"feature" is harmless, but I think there are more chances that someone
will say "hey, /proc/partitions has changed, now my software doesn't work"
then "hey where did my new 2.6.25 feature go". nbd devices are also
excluded, maybe for very same (unknown to me) reasons.

When we get any IO error during a recovery (rebuilding a spare), we abort
the recovery and restart it.
For RAID6 (and multi-drive RAID1) it may not be best to restart at the
beginning: when multiple failures can be tolerated, the recovery may be
able to continue and re-doing all that has already been done doesn't make
sense.
We already have the infrastructure to record where a recovery is up to
and restart from there, but it is not being used properly.
This is because:
- We sometimes abort with MD_RECOVERY_ERR rather than just MD_RECOVERY_INTR,
which causes the recovery not be be checkpointed.
- We remove spares and then re-added them which loses important state
information.
The distinction between MD_RECOVERY_ERR and MD_RECOVERY_INTR really isn't
needed. If there is an error, the relevant drive will be marked as
Faulty, and that is enough to ensure correct handling of the error. So we
first remove MD_RECOVERY_ERR, changing some of the uses of it to
MD_RECOVERY_INTR.
Then we cause the attempt to remove a non-faulty device from an array to
fail (unless recovery is impossible as the array is too degraded). Then
when remove_and_add_spares attempts to remove the devices on which
recovery can continue, it will fail, they will remain in place, and
recovery will continue on them as desired.
Issue: If we are halfway through rebuilding a spare and another drive
fails, and a new spare is immediately available, do we want to:
1/ complete the current rebuild, then go back and rebuild the new spare or
2/ restart the rebuild from the start and rebuild both devices in
parallel.
Both options can be argued for. The code currently takes option 2 as
a/ this requires least code change
b/ this results in a minimally-degraded array in minimal time.

When performing a "recovery" or "check" pass on a RAID1 array, we read
from each device and possible, if there is a difference or a read error,
write back to some devices.
We use the same 'bio' for both read and write, resetting various fields
between the two operations.
We forgot to reset bv_offset and bv_len however. These are often left
unchanged, but in the case where there is an IO error one or two sectors
into a page, they are changed.
This results in correctable errors not being corrected properly. It does
not result in any data corruption.

IB/mad: Fix kernel crash when .process_mad() returns SUCCESS|CONSUMED
IPoIB: Test for NULL broadcast object in ipiob_mcast_join_finish()
MAINTAINERS: Add cxgb3 and iw_cxgb3 NIC and iWARP driver entries
IB/mlx4: Fix creation of kernel QP with max number of send s/g entries
IB/mthca: Fix max_sge value returned by query_device
RDMA/cxgb3: Fix uninitialized variable warning in iwch_post_send()
IB/mlx4: Fix uninitialized-var warning in mlx4_ib_post_send()
IB/ipath: Fix UC receive completion opcode for RDMA WRITE with immediate
IB/ipath: Fix printk format for ipath_sdma_status
If a low-level driver returns IB_MAD_RESULT_SUCCESS | IB_MAD_RESULT_CONSUMED,
handle_outgoing_dr_smp() doesn't clean up properly. The fix is to
kfree the local data and break, rather than falling through. This was
observed with the ipath driver, but could happen with any driver.
This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1027>.

Not sure how this snuck upstream, but it really doesn't belong there. We
don't need a KERN_ERR printk in the suspend path to know what's going on (at
least not anymore).
