| * libata: Power off empty portsKristen Carlson Accardi2011-05-202-3/+9
| | | | | | | | | | | | | | | | | | | | | | Give users the option of completely powering off unoccupied SATA ports using the existing min_power link_power_management_policy option. When the use selects this option on an empty port, we will power the port off by setting DET to off. For occupied ports, behavior is unchanged.

| * ATA: Don't powerdown Compaq Triflex IDE device on suspendMikulas Patocka2011-05-201-1/+22
| | | | | | | | | | | | | | | | | | | | | | | | Don't powerdown Compaq Triflex IDE device on suspend This fixes APM suspend on Compaq Armada 7400. APM BIOS doesn't suspend if IDE is powered down when suspending. The Triflex controller is found only on old Compaq boards, so this patch will hopefully have no side effects.

| * libata: Use Maximum Write Same Length to report discard size limitMartin K. Petersen2011-05-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we used Maximum Unmap LBA Count in the Block Limits VPD to signal the maximum number of sectors we could handle in a single Write Same command. Starting with SBC3r26 the Block Limits VPD has an explicit limit on the number of blocks in a Write Same. This means we can stop abusing a field related to the Unmap command and let our SAT use the proper value in the VPD (Maximum Write Same Length). Signed-off-by: Martin K.

| * pata_cm64x: fix boot crash on pariscJames Bottomley2011-05-141-4/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old IDE cmd64x checks the status of the CNTRL register to see if the ports are enabled before probing them. pata_cmd64x doesn't do this, which causes a HPMC on parisc when it tries to poke at the secondary port because apparently the BAR isn't wired up (and a non-responding piece of memory causes a HPMC). Fix this by porting the CNTRL register port detection logic from IDE cmd64x. In addition, following converns from Alan Cox, add a check to see if a mobility electronics bridge is the immediate parent and forgo the check if it is (prevents problems on hotplug controllers).

This patch removes mwifiex specific implementation and uses existing ieee80211_amsdu_to_8023s routine.

| | | * | | | cfg80211: make stripping of 802.11 header optional from AMSDUYogesh Ashok Powar2011-05-161-1/+2

This patch enhances ieee80211_amsdu_to_8023s() API by changing mandatory removing of IEEE 802.11 header from AMSDU to optional.
