pdc202xx_reset() calls pdc202xx_reset_host() twice, for both channels, while
that function actually twiddles the single, shared software reset bit -- the
net effect is a duplicated reset and horrendous 4 second delay happening not
only on a channel reset but also when dma_lost_irq() and dma_clear() methods
are called. Fold pdc202xx_reset_host() into pdc202xx_reset(), fix printk(),
and move it before the actual reset...

Commit ac95beedf8bc97b24f9540d4da9952f07221c023 (ide: add struct ide_port_ops
(take 2)) erroneously converted the driver's dma_timeout() and dma_lost_irq()
methods to call the driver's resetproc() method regardless of whether it was
defined for this specific controller while it hadn't been defined and hence
called for PDC20246. So the dma_clear() method, the successor of dma_timeout(),
shouldn't exist and the dma_lost_irq() method should be standard for PDC20246.

This patch removes the device id macros and instead uses the constants
directly.
The areas in which logic expressions where using the macros now instead
use feature/workaround flags.
No new functionality has been introduced in this patch, only clean up of

Added support for the new xps tft controller. The new core
has PLB interface support in addition to existing DCR interface.
Removed platform device support as both MicroBlaze and PowerPC
use device tree.
Previously, the dcr interface was assumed to be used in mmio mode,
and the register space of the dcr interface was precomputed and stuffed
into the device tree. This driver now makes use of the new dcr
infrastructure to represent the dcr interface. This enables the dcr
interface to be connected directly to a native dcr interface in a clean
way.
Added compatibility for ml507 dvi core.

The basic problem here that pata_legacy attaches the host, sees if it found
any devices and detaches it if none were found. With async probing, it's not
waiting until discovery is finished before deciding it has no devices and
trying the detach leading to this warning:

Because it detaches before the probe is complete.
One way to fix it would be to put an async_synchronize_full() before looking
for devices, which this patch does. A better way might be to separate libata
into its own domain and only wait for that.

The ConnectX Programmer's Reference Manual states that the "SO" bit
must be set when posting Fast Register and Local Invalidate send work
requests. When this bit is set, the work request will be executed
only after all previous work requests on the send queue have been
executed. (If the bit is not set, Fast Register and Local Invalidate
WQEs may begin execution too early, which violates the defined
semantics for these operations)
This fixes the issue with NFS/RDMA reported in

While running 20 parallel instances of dd as follows:
#!/bin/bash
for i in `seq 1 20`; do
dd if=/dev/zero of=/export/hda3/dd_$i bs=1073741824 count=1 &
done
wait
on a 16G machine, we noticed that rather than just killing the processes,
the entire kernel went down. Stracing dd reveals that it first does an
mmap2, which makes 1GB worth of zero page mappings. Then it performs a
read on those pages from /dev/zero, and finally it performs a write.
The machine died during the reads. Looking at the code, it was noticed
that /dev/zero's read operation had been changed by
557ed1fa2620dc119adb86b34c614e152a629a80 ("remove ZERO_PAGE") from giving
zero page mappings to actually zeroing the page.
The zeroing of the pages causes physical pages to be allocated to the
process. But, when the process exhausts all the memory that it can, the
kernel cannot kill it, as it is still in the kernel mode allocating more
memory. Consequently, the kernel eventually crashes.
To fix this, I propose that when a fatal signal is pending during
/dev/zero read operation, we simply return and let the user process die.

Patch fixes the bug at
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1903
when SW rfkill is invoked by 'iwconfig txpower off',
the existing connection disassociates and led off command is sent
to the device which returns error as rfkill is 'true'.
Patch fixes this by just avoiding sending the led off/on command when
disassociated. The main purpose of the led_disassociate callback
is to start or stop the blinking.
There are three states in led
1) Always on when radio is on
2) Always off when radio is off
3) blink when associated and if there is some traffic.
In this callback 'allow_blinking' needs to be set false
when associated, as LED will be always on.
