This fixes MPC834x MDS (formerly SYS) and ITX platform code to get IRQ data (including PCI) from the device tree, and to use the new IPIC code.
renamed defconfig (sys -> mds), left one redundant NULL assignment in mpc83xx_pcibios_fixup to keep the compiler happy.

This converts ipic code to Benh's IRQ mods. For the IPIC, IRQ sense values in the device tree equal those in include/linux/irq.h; that's 8 for low assertion (most internal IRQs on mpc83xx), and 2 for high-to-low change.
spinlocks added to [un]mask, ack operations; default handler and type now set in host_map; and redundant condition check eliminated.

The code to handle cloned skb overwriting is unnecessary in the
sky2 driver and is buggy. The bug is that pskb_expand_head can change the
skb but the driver has already mapped in the header.
Since the sky2 hardware doesn't need to overwrite memory, the buggy
code can just be removed; it was mistakenly copied from the tg3
driver.

This patch enables the ipw2200 driver to support passive scanning as
offered by the wireless extensions. For this, I enhanced the ipw_wx_set_scan
function in such a way that it differentiates between a passive and an
active scan request. Additionally, I added a new function called
ipw_request_passive_scan that is similiar to the ipw_request_scan
function to perform passive scans. Last but not least, I added a field
(in fact it is a work_struct struct) called request_passive_scan to
the ipw_priv struct.

This patch traps the case when the essid is being set to its
current value. If the essid is being set again and we are already
associated, chances are some other parameters have also been altered.

This patch cleanups the ipw_wx_set_essid code and forces a reassociation
when setting the essid to "any". I have tested this patch with iwconfig. It
makes ipw2200 compliant with all the cases mentioned in the iwconfig man
page. The commands
iwconfig iface essid any
iwconfig iface essid -- any
iwconfig iface essid off
iwconfig iface essid on
all seemed to work correctly. None of this worked before the patch.
Note, this patch treats
iwconfig iface essid
iwconfig iface essid ""
The same. It produces an error message: essid: Unknown host.
Since an essid of "" is not mentioned in the iwconfig man page.

The SIOCGIWFREQ ioctl fills the request structure's freq field by setting
the exponent to 0 and the mantissa to the current channel number. The
iwconfig tool works around this behaviour by looking up the frequency
from the channel table if a frequency below 1kHz is returned, other tools
(e.g. kwlaninfo) don't. According to the comment in the iwconfig source
the driver is supposed to return the frequency, not the channel number.

Moving part of the debugging code from IPW_DEBUG to IPW_LL_DEBUG (low level
debugging) and make IPW_DEBUG be always enabled. IPW_LL_DEBUG still needs
to be enabled by selecting CONFIG_IPW2200_DEBUG. But it is highly
deprecated for normal users since it adds higher debug verbosity in driver

The IEEE80211 TKIP and WEP Tx and Rx paths use the same crypto_tfm to encrypt
and decrypt data. During the encrypt and decrypt process, both of them will
set a new key to crypto_tfm. If they happen on the same time, it will
corrupt the crypto_tfm. Thus users will receive an ICV error or Michael MIC
error. This only likely to happen on SMP box with heavy traffic both on Tx
and Rx. The patch use two sets of crypto_tfms to avoid this problem.

Convert the bitfields in the bcm43xx DMA code to properly
aligned u8 booleans. These flags are accessed in the DMA
hotpath, so it's a good idea to waste a few bytes of memory
for the sake of speed by not requiring masking (and probably
shifting) of the bitfields.
