2011-07-21iwlagn: rename iwlagn_set_dynamic_keyJohannes Berg
We now have iwlagn_set_dynamic_key() and iwl_set_dynamic_key() which is confusing, rename the former to iwlagn_send_sta_key() to better reflect what it does -- it only sends a command and doesn't change driver state.

2011-07-21iwlagn: track beacon interval sent to deviceJohannes Berg
Sometimes, when mac80211 changes the beacon interval or when it isn't yet set in mac80211 before association, the uCode will sysassert because we send it confusing RXON timing vs. PAN parameters. To fix this, track the last beacon interval sent to the device and use that in PAN parameter calculations. This fixes a bug during P2P group formation as a client (and possibly association to a regular AP) while connected to another AP.

2011-07-21iwlagn: implement WoWLANJohannes Berg
Implement WoWLAN support in iwlagn. The device supports a number of wakeup triggers and can do GTK rekeying when asleep (if HW crypto is used). Unfortunately, we need to disconnect from the AP after resume since we can't yet get all the info out of the wowlan uCode to stay connected safely.

2011-07-21iwlagn: rewrite HW cryptoJohannes Berg
As I just discovered while doing WoWLAN, HW crypto is done wrong for GTKs: they should be programmed for the AP station ID (in the managed mode case) and the HW can actually deal with multiple group keys per station as well (which is useful in IBSS RSN but that I've chosen not to use this). To fix all this, modify the way keys are sent to the device and key offsets are allocated. After these changes, key offsets are stored into the hw_key_idx which we can then track for the key lifetime, not relying on our sta_cmd array. WEP default keys get special treatment, of course. Additionally, since I had the API for it, we can now pre-fill TKIP phase 1 keys for RX now that we can obtain the P1K from mac80211, a capability I had added for WoWLAN initially. Finally, some keys simply don't need to be added into the device's key cache -- a key that won't be used for RX is only needed in the TX header, so "pretend" to have accepted any key without adding it into the device -- no need to use up key space there for it.

2011-07-21iwlagn: add comment to warn about WoWLAN in resume / suspend flowsEmmanuel Grumbach
WoWLAN may need the NIC even after suspend. One should not do anything to the NIC in the bus level, since one cannot check whether WoWLAN is enabled or not. Same for resume.

2011-07-21iwlagn: iwl_bus holds drv_data as void * instead of iwl_privEmmanuel Grumbach

2011-07-21iwlagn: simplify the bus architectureEmmanuel Grumbach
Call iwl_probe with a ready iwl_bus struct. This means that the bus layer assigns the irq, dev and iwl_bus_ops pointers to iwl_bus before giving it to iwl_probe. The device specific struct is allocated together with the common iwl_bus struct by the bus specific layer. The pointer to the aggregate struct is passed to the upper layer that holds a pointer to iwl_bus instead of an embedded iw_bus. The private data given to the PCI subsystem is now iwl_bus and not iwl_priv. Provide bus_* inliners on the way in order to simplify the syntax. Rename iwl-pci.h -> iwl-bus.h since it is bus agnostic and represent the external of the bus layer.

2011-07-21ARM: CPU hotplug: ensure we migrate all IRQs off a downed CPURussell King
Our selection of interrupts to consider for IRQ migration is sub- standard. We were potentially including per-CPU interrupts in our migration strategy, but omitting chained interrupts. This caused some interrupts to remain on a downed CPU. We were also trying to migrate interrupts which were not migratable, resulting in an OOPS. Instead, iterate over all interrupts, skipping per-CPU interrupts or interrupts whose affinity does not include the downed CPU, and attempt to set the affinity for every one else if their chip implements irq_set_affinity().

2011-07-21ARM: CPU hotplug: pass in proper affinity mask on IRQ migrationRussell King
Now that the GIC takes care of selecting a target interrupt from the affinity mask, we don't need all this complexity in the core code anymore. Just detect when we need to break affinity. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-07-21ARM: GIC: avoid routing interrupts to offline CPUsRussell King
The irq_set_affinity() method can be called with masks which include offline CPUs. This allows offline CPUs to have interrupts routed to them by writing to /proc/irq/*/smp_affinity after hotplug has taken a CPU offline. Fix this by ensuring that we select a target CPU present in both the required affinity and the online CPU mask. Ensure that we return IRQ_SET_MASK_OK (which happens to be 0) on success to ensure generic code copies the new mask into the irq_data structure.

2011-07-21ARM: CPU hotplug: fix abuse of irqdesc->nodeRussell King

Furthermore, jump back entry == 0 should be used to signal that the jump back or preserve context is not enabled in the original kernel. But in the current implementation the stack position used for function call return address is not cleared context preservation is disabled. The patch fixes this bug.
