2010-10-20virtio: console: Don't block entire guest if host doesn't read dataAmit Shah
If the host is slow in reading data or doesn't read data at all, blocking write calls not only blocked the program that called write() but the entire guest itself. To overcome this, let's not block till the host signals it has given back the virtio ring element we passed it. Instead, send the buffer to the host and return to userspace. This operation then becomes similar to how non-blocking writes work, so let's use the existing code for this path as well. This code change also ensures blocking write calls do get blocked if there's not enough room in the virtio ring as well as they don't return -EAGAIN to userspace.

2010-10-18mxc_nand: do not depend on disabling the irq in the interrupt handlerSascha Hauer
This patch reverts the driver to enabling/disabling the NFC interrupt mask rather than enabling/disabling the system interrupt. This cleans up the driver so that it doesn't rely on interrupts being disabled within the interrupt handler. For i.MX21 we keep the current behaviour, that is calling enable_irq/disable_irq_nosync to enable/disable interrupts. This patch is based on earlier work by John Ogness.

2010-10-18i2c-imx: do not allow interruptions when waiting for I2C to completeMarc Kleine-Budde
The i2c_imx_trx_complete() function is using wait_event_interruptible_timeout() to wait for the I2C controller to signal that it has completed an I2C bus operation. If the process that causes the I2C operation receives a signal, the wait will be interrupted, returning an error. It is better to let the I2C operation finished before handling the signal (i.e. returning into userspace). It is safe to use wait_event_timeout() instead, because the timeout will allow the process to exit if the I2C bus hangs. It's also better to allow the I2C operation to finish, because unacknowledged I2C operations can cause the I2C bus to hang.

Revert commit 54672386ccf36ffa21d1de8e75624af83f9b0eeb "firewire: ohci: fix up configuration of TI chips". It caused massive slow-down and data corruption with a TSB82AA2 based StarTech EC1394B2 ExpressCard and FireWire 800 harddisks. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/657081 http://thread.gmane.org/gmane.linux.kernel.firewire.user/4013 The fact that some card EEPROMs do not program these enhancements may be related to TSB81BA3 phy chip errata, if not to bugs of TSB82AA2 itself.

2010-10-15v4l1: fix 32-bit compat microcode loading translationLinus Torvalds
The compat code for the VIDIOCSMICROCODE ioctl is totally buggered. It's only used by the VIDEO_STRADIS driver, and that one is scheduled to staging and eventually removed unless somebody steps up to maintain it (at which point it should use request_firmware() rather than some magic ioctl). So we'll get rid of it eventually. But in the meantime, the compatibility ioctl code is broken, and this tries to get it to at least limp along (even if Mauro suggested just deleting it entirely, which may be the right thing to do - I don't think the compatibility translation code has ever worked unless you were very lucky).

2010-10-13ioat2: fix performance regressionDan Williams
Commit 0793448 "DMAENGINE: generic channel status v2" changed the interface for how dma channel progress is retrieved. It inadvertently exported an internal helper function ioat_tx_status() instead of ioat_dma_tx_status(). The latter polls the hardware to get the latest completion state, while the helper just evaluates the current state without touching hardware. The effect is that we end up waiting for completion timeouts or descriptor allocation errors before the completion state is updated. iperf (before fix): [SUM] 0.0-41.3 sec 364 MBytes 73.9 Mbits/sec iperf (after fix): [SUM] 0.0- 4.5 sec 499 MBytes 940 Mbits/sec This is a regression starting with 2.6.35.

2010-10-13ehea: Fix a checksum issue on the receive pathBreno Leitao
Currently we set all skbs with CHECKSUM_UNNECESSARY, even those whose protocol we don't know. This patch just add the CHECKSUM_COMPLETE tag for non TCP/UDP packets.

2010-10-13net: allow FEC driver to use fixed PHY supportGreg Ungerer
At least one board using the FEC driver does not have a conventional PHY attached to it, it is directly connected to a somewhat simple ethernet switch (the board is the SnapGear/LITE, and the attached 4-port ethernet switch is a RealTek RTL8305). This switch does not present the usual register interface of a PHY, it presents nothing. So a PHY scan will find nothing - it finds ID's of 0 for each PHY on the attached MII bus. After the FEC driver was changed to use phylib for supporting PHYs it no longer works on this particular board/switch setup. Add code support to use a fixed phy if no PHY is found on the MII bus. This is based on the way the cpmac.c driver solved this same problem. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: David S. Miller <davem@davemloft.net>
