Subject: [PATCH] libata: forbid port runtime pm by default
Forbid port runtime pm by default because it has known hotplug issue.
User can allow it by, for example
echo auto > /sys/devices/pci0000:00/0000:00:1f.2/ata2/power/control

Is possible that we will arm the tid_rx->reorder_timer after
del_timer_sync() in ___ieee80211_stop_rx_ba_session(). We need to stop
timer after RCU grace period finish, so move it to
ieee80211_free_tid_rx(). Timer will not be armed again, as
rcu_dereference(sta->ampdu_mlme.tid_rx[tid]) will return NULL.
Debug object detected problem with the following warning:
ODEBUG: free active (active state 0) object type: timer_list hint: sta_rx_agg_reorder_timer_expired+0x0/0xf0 [mac80211]

I get this compile failure on parisc:
drivers/pci/ats.c: In function 'ats_alloc_one':
drivers/pci/ats.c:29: error: implicit declaration of function 'kzalloc'
drivers/pci/ats.c:29: warning: assignment makes pointer from integer without a cast
drivers/pci/ats.c: In function 'ats_free_one':
drivers/pci/ats.c:45: error: implicit declaration of function 'kfree'
Because ats.c is missing linux/slab.h as an include. This patch fixes it
