Bartlomiej Zolnierkiewicz reported an atomic order-6 allocation failure
for ipw2200 firmware loading in kernel 2.6.30. High order allocation is
likely to fail and should always be avoided.

The patch fixes this problem by replacing the original order-6
pci_alloc_consistent() with an array of order-1 pages from a pci pool.
This utilized the ipw2200 DMA command blocks (up to 64 slots). The
maximum firmware size support remains the same (64*8K).

This patch fixes bug http://bugzilla.kernel.org/show_bug.cgi?id=14016

RTL8187B always needs MSR_LINK_ENEDCA flag to be set even when it is in
no link mode, otherwise it'll not be able to associate when this flag is
not set after the change "mac80211: fix managed mode BSSID handling".

By accident, setting BSSID of AP before association makes 8187B to
successfuly associate even when ENEDCA flag isn't set, which was the
case before the mac80211 change. But now the BSSID of AP we are trying
to associate is only available after association is successful, and
any attempt to associate without the needed flag doesn't work.

Change rt2x00_rf_read() and rt2x00_rf_write() to subtract 1 from the rf
register number.  This is needed because the rf registers are enumerated
starting with one.  The size of the rf register cache is just enough to
hold all registers, so writing to the highest register was corrupting
memory.  Add a check to make sure that the rf register number is valid.

This reverts commit 57921c312e8cef72ba35a4cfe870b376da0b1b87.

On request from John Linville:

	It has been shown to create a new problem.  There is work
	towards a solution to that one, but it isn't a simple
	clean-up.

Older Gcc compilers (3.4.5 tested) need additional hints in order to get
the packing of the rxpd structure (which contains a 16 bit union)
correct on the ARM processor.

struct txpd does not need these hints since it contains a 32 bit union
that packs naturally.

We need to unregister our ieee80211_hw before resetting the chip, as
the former causes firmware commands to be issued which will time out
once the chip has been reset.
