2011-06-27iwlagn: map command buffers BIDIJohannes Berg1-7/+10
Evidently, the device sometimes wants to write back to command buffers, even if I see no reason why it should. Allow it to do that.

2011-06-27iwlagn: fix cmd queue unmapJohannes Berg1-4/+1
When we stop the device while a command is in flight that uses multiple TBs, we can leak the DMA buffers for the second and higher TBs. Fix this by using iwlagn_unmap_tfd() as we do when we normally recover the entry. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>

2011-06-26mmc: queue: bring discard_granularity/alignment into line with SCSIAdrian Hunter1-6/+1
SCSI defines discard alignment as the offset to the first optimal discard. In the case of SD/MMC, that is always zero which is the default.

2011-06-26mmc: omap_hsmmc: fix ocr mask usageAnand Gadiyar1-1/+0
The OMAP HSMMC driver uses an ocr_mask to determine the list of voltages supported by the card. It populates this mask based on the list of voltages supported by the regulator that supplies the voltage. Commit 64be97822b (omap4 hsmmc: Update ocr mask for MMC2 for regulator to use) passed a fixed ocr_mask from the OMAP4 SDP board file to limit the voltage to 2.9-3.0 Volts, and updated the driver to use this mask if provided, instead of using the regulator's supported voltages. However the commit is buggy - the ocr_mask is overridden by the regulator's capabilities anyway. Fix this. (The bug shows up when a system-wide suspend is attempted on the OMAP4 SDP/Blaze platforms. The eMMC card comes up at 3V, but drops to 1.65V after the system resumes).

2011-06-26mmc: sdio: fix runtime PM path during driver removalOhad Ben-Cohen1-1/+1
After commit e1866b3 "PM / Runtime: Rework runtime PM handling during driver removal" was introduced, the driver core stopped incrementing the runtime PM usage counter of the device during the invocation of the ->remove() callback. This indirectly broke SDIO's runtime PM path during driver removal, because no one calls _put_sync() anymore after ->remove() completes. This means that the power of runtime-PM-managed SDIO cards is kept high after their driver is removed (even if it was powered down beforehand). Fix that by directly calling _put_sync() when the last usage counter is downref'ed by the SDIO bus.

The bridge currently floods packets to groups that we have never seen before to all ports. This is not required by RFC4541 and in fact it is not desirable in environment where traffic to unregistered group is always present.
