On resuming, the opmode may have to be able to talk to the WoWLAN/D3 firmware in order to query it about its status and wakeup reasons. To do that, the opmode has to call the new d3_resume() transport API which will set up the device for command communcation.

Writing 130 dwords into the device one by one is rather inefficient, every one needs to lock, grab NIC access (a few register reads/writes) and then write the address and data registers. Use the new memory clearing function to make this easier and faster. Reviewed-by: NEmmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Enabling the RF-kill interrupt is sufficient for getting RF-kill notifications, and no other interrupt is needed as the device isn't functional when suspended and will be restarted/reconfigured when mac80211 resumes it later.

Synchronizing the IRQ is pointless when we will then enable the RF-Kill interrupt again, but is needed before we free it and the data needed to handle IRQs; move it to the free function. Simiarly, cancelling the replenish work struct can move to the function that frees the RX data structures.

Eliminate struct map_info from dm-snap. map_info->ptr was used in dm-snap to indicate if the bio was tracked. If map_info->ptr was non-NULL, the bio was linked in tracked_chunk_hash. This patch removes the use of map_info->ptr. We determine if the bio was tracked based on hlist_unhashed(&c->node). If hlist_unhashed is true, the bio is not tracked, if it is false, the bio is tracked. Signed-off-by: NMikulas Patocka <mpatocka@redhat.com> Signed-off-by: NAlasdair G Kergon <agk@redhat.com>

Don't use map_info any more in dm-raid1. map_info was used for writes to hold the region number. For this purpose we add a new field dm_bio_details to dm_raid1_bio_record. map_info was used for reads to hold a pointer to dm_raid1_bio_record (if the pointer was non-NULL, bio details were saved; if the pointer was NULL, bio details were not saved). We use dm_raid1_bio_record.details->bi_bdev for this purpose. If bi_bdev is NULL, details were not saved, if bi_bdev is non-NULL, details were saved.

Introduce a field per_bio_data_size in struct dm_target. Targets can set this field in the constructor. If a target sets this field to a non-zero value, "per_bio_data_size" bytes of auxiliary data are allocated for each bio submitted to the target. These data can be used for any purpose by the target and help us improve performance by removing some per-target mempools. Per-bio data is accessed with dm_per_bio_data. The argument data_size must be the same as the value per_bio_data_size in dm_target. If the target has a pointer to per_bio_data, it can get a pointer to the bio with dm_bio_from_per_bio_data() function (data_size must be the same as the value passed to dm_per_bio_data).
