2011-11-28regulator: twl: fix twl4030 support for smps regulatorsTero Kristo
SMPS regulator voltage control differs from the one of the LDO ones. Current TWL code was using LDO regulator ops for controlling the SMPS regulators, which fails. This was fixed fixed by adding separate regulator type which uses correct logic and calculations for the voltage levels.

2011-11-24virtio-pci: make reset operation saferMichael S. Tsirkin
virtio pci device reset actually just does an I/O write, which in PCI is really posted, that is it can complete on CPU before the device has received it. Further, interrupts might have been pending on another CPU, so device callback might get invoked after reset. This conflicts with how drivers use reset, which is typically: reset unregister a callback running after reset completed can race with unregister, potentially leading to use after free bugs. Fix by flushing out the write, and flushing pending interrupts. This assumes that device is never reset from its vq/config callbacks, or in parallel with being added/removed, document this assumption. Signed-off-by: Michael S.

2011-11-23ehea: Reduce memory usage in buffer poolsAnton Blanchard
Now that we enable multiqueue by default the ehea driver is using quite a lot of memory for its buffer pools. With 4 queues we consume 64MB in the jumbo packet ring, 16MB in the medium packet ring and 16MB in the tiny packet ring. We should only fill the jumbo ring once the MTU is increased but for now halve it's size so it consumes 32MB. Also reduce the tiny packet ring, with 4 queues we had 16k entries which is overkill.

2011-11-23qlge: fix size of external list for TX address descriptorsThadeu Lima de Souza Cascardo
When transmiting a fragmented skb, qlge fills a descriptor with the fragment addresses, after DMA-mapping them. If there are more than eight fragments, it will use the eighth descriptor as a pointer to an external list. After mapping this external list, called OAL to a structure containing more descriptors, it fills it with the extra fragments. However, considering that systems with pages larger than 8KiB would have less than 8 fragments, which was true before commit a715dea3c8e, it defined a macro for the OAL size as 0 in those cases. Now, if a skb with more than 8 fragments (counting skb->data as one fragment), this would start overwriting the list of addresses already mapped and would make the driver fail to properly unmap the right addresses on architectures with pages larger than 8KiB. Besides that, the list of mappings was one size too small, since it must have a mapping for the maxinum number of skb fragments plus one for skb->data and another for the OAL. So, even on architectures with page sizes 4KiB and 8KiB, a skb with the maximum number of fragments would make the driver overwrite its counter for the number of mappings, which, again, would make it fail to unmap the mapped DMA addresses.

2011-11-23regulator: TPS65910: Fix VDD1/2 voltage selector countAfzal Mohammed
Count of selector voltage is required for regulator_set_voltage to work via set_voltage_sel. VDD1/2 currently have it as zero, so regulator_set_voltage won't work for VDD1/2. Update count (n_voltages) for VDD1/2. Output Voltage = (step value * 12.5 mV + 562.5 mV) * gain With above expr, number of voltages that can be selected is step value count * gain count constant for gain count will be called VDD1_2_NUM_VOLT_COARSE existing constant for step value count is VDD1_2_NUM_VOLTS, use VDD1_2_NUM_VOLT_FINE instead to make clear that step value is not the only component in deciding selectable voltage count Signed-off-by: Afzal Mohammed <afzal@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
