A bug in the ov7670 sensor causes it to introduce noise unless the CLKRC
register is rewritten *after* setting the image mode. Naturally,
resetting CLKRC in this way will cause other modes to fail. So
carefully poke the register only when indicated.

The proper method for powering down the sensor on OLPC systems has
changed somewhat; in particular, the sensor must be powered down
completely (rather than simply told to power down) or the associated
"camera active" LED will stay on.

dvb-core is not started early enough when device drivers that use dvb are
compiled in so dvb_register_device fails (silently) since dvb_class is
NULL, this runs dvb_init using subsys_initcall instead of module_init.
dvb_register_device will now check the return value of class_device_create.

that change
Reverted the change to struct v4l2_pix_format. I completely missed that
this struct was used by existing ioctls so that changing it broke the ABI.
I will have to think of another way of setting the top/left coordinates
but for now this change is reverted to preserve compatibility.

[IA64] fix kmalloc(0) in arch/ia64/pci/pci.c

Hiroyuki Kamezawa reported the problem that pci_acpi_scan_root() of
ia64 might call kmalloc_node() with zero size.
Currently ia64's pci_acpi_scan_root() assumes that _CRS method of root
bridge has at least one resource window. But, the root bridges that
has no resource window must be taken into account.

Unwinding a running task has proven problematic.
In one instance, the running task was attempting to unwind itself and
received an interrupt between when get_wchan allocated local variables on
the stack and when unw_init_from_blocked_task was called which resulted
in unw_init_frame_info to place this tasks task_struct pointer over the
switch stack's ar_bspstore entry.

Sam's recent change in 7664709b44a13e2e0b545e2dd8e7b8797a1748dc
broke things for us because we ended up with *(.text.*) before
*(.text), whereas previously *(.text) was first. This was
important because the start of the text section contains the
kernel entry point.
In fact, we don't need that *(.text.*) thing anymore and it
incorrectly matched .text.init.refok, thus putting it before
.text. .. ouch !

pmc.c has:
#ifndef MMCR0_PMA0
#define MMCR0_PMA0 0
This one took a while to find. Unfortunately its the wrong define
(number 0 vs letter O). Its probably worth removing this override, since
if our includes get screwed up we will have the same (hard to debug)
failure.
Fix it simply for now, so that we can backport to stable.

smp_call_function_map() was not safe against preemption to another
cpu: its test for removing self from map was outside the spinlock.
Rearrange it a little to fix that.
smp_call_function_single() was also wrong: now get_cpu() before
excluding self, as other architectures do.

"netif_poll_enable can only be called if you've previously called

Removing the call to netif_poll_enable in e1000_open should fix this issue,
the only other call to netif_poll_enable is in e1000_up() which is only
reached after a device reset or resume.

The IB CM uses an idr for local id allocations, with a running counter
as start_id. This fails to generate distinct ids if
1. An id is constantly created and destroyed
2. A chunk of ids just beyond the current next_id value is occupied
This in turn leads to an increased chance of connection request being
mis-detected as a duplicate, sometimes for several retries, until
next_id gets past the block of allocated ids. This has been observed
in practice.
As a fix, remember the last id allocated and start immediately above it.
This also fixes a problem with the old code, where next_id might
overflow and become negative.

SRQ WR leakage has been observed with IPoIB/CM: e.g. flipping ports on
and off will, with time, leak out all WRs and then all connections
will start getting RNR NAKs. Fix this in the way suggested by spec:
move the QP being destroyed to the error state, wait for "Last WQE
Reached" event and then post WR on a "drain QP" connected to the same
CQ. Once we observe a completion on the drain QP, it's safe to call
ib_destroy_qp.

Pass the number of WQEs for the send queue and their size from userspace
to the kernel to avoid having to keep the QP size calculations in sync
between the kernel driver and libmlx4. This fixes a bug seen with the
current mlx4_ib driver and current libmlx4 caused by a difference in the
calculated sizes for SQ WQEs. Also, this gives more flexibility for
userspace to experiment with using multiple WQE BBs for a single SQ WQE.

or to the ERROR state, but mlx4 firmware does not support this and
returns an error if we try. Fix the RESET to RESET transition by

moving the QP from RESET to INIT with dummy parameters and then

Global CM packets used by rmda_cm were being sent with a GRH:hopLimit
of zero, causing them to be dropped by the router. The problem is a
missing initialization of the hop_limit field in mthca_read_ah(),
which was called by build_mlx_header() when sending a MAD on QP1.

max_qp_dest_rdma is already in natural units - no need to shift. This
was discovered by a test that deliberately requests more outstanding
atomic operation than the device supports.
