The path grouping can fail due to non-unique pathgroup-IDs. The source for
the CPU-ID part of the ID was incorrectly specified on 64 bit systems.
Additionally, the length of the ID was too large due to incorrect data packing
declaration. Fix CPU-ID lowcore address and add missing packing declaration.

When ipoib_stop() is called it first calls netif_stop_queue() to stop
the kernel from passing more packets to the network driver. However,
the completion handler may call netif_wake_queue() re-enabling packet
transfer.
This might result in leaks (we see AH leaks which we think can be
attributed to this bug) as new packets get posted while the interface
is going down.

If an error is reported by a drive in a RAID array (which is done via
bi_end_io - in interrupt context), we call md_error and md_new_event which
calls sysfs_notify. However sysfs_notify grabs a mutex and so cannot be
called in interrupt context.
This patch just creates a variant of md_new_event which avoids the sysfs
call, and uses that. A better fix for later is to arrange for the event to
be called from user-context.
Note: avoiding the sysfs call isn't a problem as an error will not, by
itself, modify the sync_action attribute. (We do still need to
wake_up(&md_event_waiters) as an error by itself will modify /proc/mdstat).

Fixed releasing already-allocated regions when a later request fails, and
forward-ported it to HEAD.
Some BIOSes reserve disjoint I/O regions in their ACPI tables for the IPMI
controller. This causes problems when trying to register the entire I/O

Change the binary output format to actual ACPI TCPA log structure since the
current format does not contain all event-data information that need to
verify the PCRs in TPM. tpm_binary_bios_measurements_show() uses
get_event_name() to convert the binary event-data to ascii format, and puts
them as binary. However, to verify the PCRs, the event-data must be a
actual binary event-data used by SHA1 calc. in BIOS.
So, I think actual ACPI TCPA log is good for this binary output format.
That way, any userland tools easily parse this data with reference to TCG

update s_rdma_sge. This didn't happen very often naturally but was more
frequent with 1 byte RDMA reads. Rather than adding more locking or

This loop that sets up the hash_table has problems.
Careful examination will show that the last time through, everything but
the first line is pointless. This is because all it does is change 'cur'
and 'size' and neither of these are used after the loop. This should ring
warning bells... That last time through the loop,
size += conf->strip_zone[cur].size
can index off the end of the strip_zone array. Depending on what it finds
there, it might exit the loop cleanly, or it might spin going further and
further beyond the array until it hits an unmapped address.
This patch rearranges the code so that the last, pointless, iteration of
the loop never happens. i.e. the one statement of the last loop that is
needed is moved the the end of the previous loop - or to before the loop
starts - and the loop counter starts from 1 instead of 0.

0x0258 of the PT880.

Fix some outstanding issues with the pxa2xx_spi driver when running on a
PXA270:
- Wrong timeout calculation in the setup function due to different
peripheral clock rates in the PXAxxx family.
- Bad handling of SSSR_TFS interrupts in interrupt_transfer function.
- Added locking to interface between the pump_messages workqueue and the
pump_transfers tasklet.
Much thanks to Juergen Beisert for the extensive testing on the PXA270.

The OSC set and query functions do not allocate enough space for return
values, and set the output buffer length to a false, too large value. This
causes the acpi-ca code to assume that the output buffer is larger than it
actually is, and overwrite memory when copying acpi return buffers into
this caller provided buffer. In some cases this can cause kernel oops if
the memory that is overwritten is a pointer. This patch will change these
calls to use a dynamically allocated output buffer, thus allowing the
acpi-ca code to decide how much space is needed.

It looks like the generic ide code now wants ide_init_hwif_ports() to set
the parent struct device into the ide_hw structure (new field ?). Without
this, the mac ide code can cause the ide probing code to explode in flames
in sysfs registration due to what looks like a stale pointer in there
(happens when removing/re-inserting one of the hotswap media bays on some
laptops).

There has been a longstanding problem with the Matrox G450 and perhaps
other similar cards, with modes "above" 1280x1024-60 on ppc/ppc64 boxes
running Linux. Higher resolutions and/or higher refresh rates resulted in
a very noticably "jittery" display, and sometimes no display, depending on
the physical monitor. This patch fixes that problem on the systems I have
easy access to...
I've tested with SLES9SP3 (2.6.5+ kernel) and 2.6.16-rc6 custom kernels on
an IBM eServer p5 520 w/G450 (a.k.a GXT135P on IBM's ppc64 systems), and a
colleague of mine (Ian Romanick) tested it successfully on an Apple ppc32
box (w/GXT135P). I also tested it on IA32 box I have with a GXT135P to
verify that it didn't obviously break anything. In my testing, I covered
single-card, single and dual-head setups using both HD15 and DVI-D signals,
on both the IA32 and ppc64 boxes. While everything appeared fine on both
boxes, I did encounter one problem: I can't get any signal on the DVI-D
output on the ppc64 box. However, this is also the case without my patch.
I just noticed that screen-blanking only occurs on the primary display as
well.

Bring back this recently-reverted patch, only fixed.
Original changelog:
From: Ayaz Abdulla <aabdulla@nvidia.com>
This patch fixes the issues with multiple irqs.
I am resending based on feedback. I decoupled the dma mask for
consistent memory and fixed leak with multiple irq in error path.
Thanks to Manfred for catching the spin lock problem.
Fix it:
From: Manfred Spraul <manfred@colorfullife.com>
Fix bug introduced by ebf34c9b6f, covered in

Remove second instance of the request_irq() calls: they were moved
from nv_open into nv_request_irq.
