e9414b6b3f iwl3945: fix deep sleep when removing the driver.
A warning message "MAC is in deep sleep" sometimes happen when user removes
the driver.  This warning is related to card not being ready. In __iwl3945_down
function some of the going down steps are in wrong order, to fix this this patch
do the following:
	1- make sure we are calling iwl3945_apm_reset and iwl3945_apm_stop
	   in the right order.

	2- make sure we set CSR_GP_CNTRL_REG_FLAG_INIT_DONE in apm_reset before
	   poll on CSR_GP_CNTRL_REG_FLAG_MAC_CLOCK_READY.

	3- set correct polling counter.

This fixes bug

c0af96a6e6 iwl3945: Use iwl-rfkill

move the agn one to iwlcore, and so we can get rid of the 3945 ones.

6cd0b1cb87 iwlagn: fix hw-rfkill while the interface is down
Currently iwlagn is not able to report hw-killswitch events while the
interface is down. This has implications on user space tools (like
NetworkManager) relying on rfkill notifications to bring the interface
up once the wireless gets enabled through a hw killswitch.

Thus, enable the device already in iwl_pci_probe instead of iwl_up
and enable interrups while the interface is down in order to get
notified about killswitch state changes. The firmware loading is still
done in iwl_up.

Currently iwl3945 is not able to report hw-killswitch events while the
interface is down. This has implications on user space tools (like
NetworkManager) relying on rfkill notifications to bring the interface
up once the wireless gets enabled through a hw killswitch.

Thus, enable the device already in iwl3945_pci_probe instead of iwl3945_up
and poll the CSR_GP_CNTRL register to update the killswitch state every
two seconds. The polling is only needed on 3945 hardware as this adapter
does not use interrupts to signal rfkill changes to the driver (in case no
firmware is loaded). The firmware loading is still done in iwl3945_up.

9c74d9fbd5 iwl3945: Change crypto parameter name
Now that we're using iwl_mod_params, we want our module parameters names to be
in sync with the structure.
So, to set iwl_mod_params.sw_crypto, we'd better use a "swcrypto" parameter
name instead of the "hwcrypto" current one.
Moreover, by setting the decrypted flag properly, this patch also fixes the HW
crypto path for 3945 (the current code is not setting it when running HW
crypto).

 * IEEE80211_HW_SUPPORTS_DYNAMIC_PS - indicates dynamic PS on the device

It also adds documentation for all this which explains how to set the
various flags.

Additionally, it fixes a few things:
 * a spot where && was used to test flags
 * enable CONF_PS only when associated again

d20b3c65f2 iwl3945: iwl3945_queue and iwl3945_channel_info replacement
This patch replaces the queue and channel info 3945 structures with the iwl
ones.

The initial goal was to replace the channel info structure. Once we do that,
and then include iwl-dev.h instead of iwl-3945.h, we still get build errors
due to several routines and macro redefinitions. This is why this patch also
includes:
- TFD39_MAX_PAYLOAD definition for 3945.
- CMD_SIZE, CMD_HUGE, CMD_SKB duplication removal.
- iwl3945_queue replacement in order to also get rid of the duplicated
get_cmd_index routine.

Getting rid of any of those needs the iwl-dev.h inclusion which then creates
build errors due to definitions duplication. This is why we include all those
in the same patch.

73e1a65d3c iwlwifi: remove CMD_WANT_SKB flag if send_cmd_sync failure
In function iwl_send_cmd_sync(), if the flag CMD_WANT_SKB is set but
we are not provided with a valid SKB (cmd->meta.u.skb == NULL), we need
to remove the CMD_WANT_SKB flag from the TX cmd queue. Otherwise in case
the cmd comes in later, it will possibly set an invalid address. Thus
it causes an invalid memory access.

This fixed the bug http://bugzilla.kernel.org/show_bug.cgi?id=11326.

1061787967 iwlwifi: Fix typo in iwl-commands.h for CCK rate bit range.
My first (minor) patch, hopefully this is correct.

Fix a typo in iwl-commands.h for CCK rates which needs 7 bits and not 4.

This patch removes unused parameter and unused local variable in
methods in iwl-tx.c:

- Remove a parameter (is_unicast) from iwl_tx_cmd_build_basic().

- Remove an unused variable name unicast from iwl_tx_skb().

91f39e8eea iwlwifi: indicate txpower is off in sysfs
The patch checks if the radio is disabled before displaying the tx power
level. Previously when the txpower was set off show_tx_power still
returned the prior power level. Now it will indicate the power has been
turned off.

f1bc4ac61f iwlwifi: use GFP_KERNEL to allocate Rx SKB memory
Previously we allocate Rx SKB with GFP_ATOMIC flag. This is because we need
to hold a spinlock to protect the two rx_used and rx_free lists operation
in the rxq.

	spin_lock();
	...
	element = rxq->rx_used.next;
	element->skb = alloc_skb(..., GFP_ATOMIC);
	list_del(element);
	list_add_tail(&element->list, &rxq->rx_free);
	...
	spin_unlock();

After spliting the rx_used delete and rx_free insert into two operations,
we don't require the skb allocation in an atomic context any more (the
function itself is scheduled in a workqueue).

	spin_lock();
	...
	element = rxq->rx_used.next;
	list_del(element);
	...
	spin_unlock();
	...
	element->skb = alloc_skb(..., GFP_KERNEL);
	...
	spin_lock()
	...
	list_add_tail(&element->list, &rxq->rx_free);
	...
	spin_unlock();

This patch should fix the "iwlagn: Can not allocate SKB buffers" warning
we see recently.
