2010-12-24libata: issue DIPM enable commands with LPM state updatedTejun Heo
Low level drivers may behave differently depending on the current link->lpm_policy. During ata_eh_set_lpm(), DIPM enable commands are issued after the successful completion of ap->ops->set_lpm(), which means that the controller is already in the target state. This causes DIPM enable commands to be processed with mismatching controller power state and link->lpm_policy value. In ahci, link->lpm_policy is used to ignore certain PHY events if LPM is enabled; however, as DIPM commands are issued with stale link->lpm_policy, they sometimes end up triggering these conditions and get aborted leading to LPM configuration failure. Fix it by updating link->lpm_policy before issuing DIPM enable commands.

2010-12-24libata: no special completion processing for EH commandsTejun Heo
ata_qc_complete() contains special handling for certain commands. For example, it schedules EH for device revalidation after certain configurations are changed. These shouldn't be applied to EH commands but they were. In most cases, it doesn't cause an actual problem because EH doesn't issue any command which would trigger special handling; however, ACPI can issue such commands via _GTF which can cause weird interactions. Restructure ata_qc_complete() such that EH commands are always passed on to __ata_qc_complete(). stable: Please apply to -stable only after 2.6.38 is released.

2010-12-24libata-sff: fix HSM_ST_ERR handling in __ata_sff_port_intr()Tejun Heo
While separating out BMDMA irq handler from SFF, commit c3b28894 (libata-sff: separate out BMDMA irq handler) incorrectly made __ata_sff_port_intr() consider an IRQ to be an idle one if the host state was transitioned to HSM_ST_ERR by ata_bmdma_port_intr(). This makes BMDMA drivers ignore IRQs reporting host bus error which leads to timeouts instead of triggering EH immediately. Fix it by making __ata_sff_port_intr() consider the IRQ to be an idle one iff the state is HSM_ST_IDLE. This is equivalent to adding HSM_ST_ERR to the "break"ing case but less error-prone.

2010-12-24sh: intc: Initialize radix tree gfp mask explicitly.Paul Mundt
Presently the root node is initialized by way of kzalloc on the parent data structure, which by chance happens to do the bulk of what an explicit initialization does with GFP_NOWAIT semantics. This however is more by luck than by design, and as we ideally want to permit radix node allocations access to the emergency pools anyways, add in the proper initializer with the desired mask.

On Simics, when read N bytes that exceed the amount of data in receive FIFO, we can't read the data out, that is we can't clear the rx FIFO, then the CPU will loop on the espi rx interrupt.

2010-12-24of/i2c: Fix request module by aliasDavid Daney
If we are registering an i2c device that has a device tree node like this real-world example: rtc@68 { compatible = "dallas,ds1337"; reg = <0x68>; }; of_i2c_register_devices() will try to load a module called ds1337.ko. There is no such module, so it will fail. If we look in modules.alias we will find entries like these: . . . alias i2c:ds1339 rtc_ds1307 alias i2c:ds1338 rtc_ds1307 alias i2c:ds1337 rtc_ds1307 alias i2c:ds1307 rtc_ds1307 alias i2c:ds1374 rtc_ds1374 . . . The module we want is really called rtc_ds1307.ko. If we request a module called "i2c:ds1337", the userspace module loader will do the right thing (unless it is busybox) and load rtc_ds1307.ko. So we add the I2C_MODULE_PREFIX to the request_module() string. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2010-12-23cs5535-gpio: handle GPIO regs where higher (clear) bits are setAndres Salomon
The default for non-READ_BACK GPIO regs is to have the clear bits set; this means that our original errata fix was too simplistic. This changes it to the following behavior: - when setting GPIOs, ignore the higher order bits (they're for clearing, we don't need to care about them). - when clearing GPIOs, keep all the bits, but unset (via XOR) the lower order bit that negates the clear bit that we care about. That is, if we're clearing GPIO 26 (val = 0x04000000), we first XOR what's currently in the register with 0x0400 (GPIO 26's SET bit), and then OR that with the GPIO 26's CLEAR bit.

The edge detect status GPIOs function differently from the other atomic model CS5536 GPIO registers; writing 1 to the high bits clears the GPIO, but writing 1 to the lower bits also clears the bit. This means that read-modify-write doesn't actually work for it, so don't apply the errata here. If a negative edge status gets lost after resume.. well, we tried our best!

2010-12-22watchdog: Fix null pointer dereference while accessing rdc321x platform_dataFlorian Fainelli
rdc321x-wdt currently fetches its driver specific data by using the platform_device->platform_data pointer, this is wrong because the mfd device which registers our platform_device has been added using mfd_add_device() which sets the platform_device->driver_data pointer instead.
