2011-02-23DM9000B: Fix PHY power for network down/upHenry Nestler1-3/+4
DM9000 revision B needs 1 ms delay after PHY power-on. PHY must be powered on by writing 0 into register DM9000_GPR before all other settings will change (see Davicom spec and example code). Remember, that register DM9000_GPR was not changed by reset sequence. Without this fix the FIFO is out of sync and sends wrong data after sequence of "ifconfig ethX down ; ifconfig ethX up".

2011-02-23Btrfs: fix fiemap bugs with delallocChris Mason3-42/+224
The Btrfs fiemap code wasn't properly returning delalloc extents, so applications that trust fiemap to decide if there are holes in the file see holes instead of delalloc. This reworks the btrfs fiemap code, adding a get_extent helper that searches for delalloc ranges and also adding a helper for extent_fiemap that skips past holes in the file.

2011-02-23Input: serio/gameport - use 'long' system workqueueDmitry Torokhov2-2/+2
Commit 8ee294cd9def0004887da7f44b80563493b0a097 converted serio subsystem event handling from using a dedicated thread to using common workqueue. Unfortunately, this regressed our boot times, due to the fact that serio jobs take long time to execute. While the new concurrency managed workqueue code manages long-playing works just fine and schedules additional workers as needed, such works wreck havoc among remaining users of flush_scheduled_work(). To solve this problem let's move serio/gameport works from system_wq to system_long_wq which nobody tries to flush.

2011-02-23ALSA: usb-audio: fix oops due to cleanup race when disconnectingTakashi Iwai3-2/+10
When a USB audio device is disconnected, snd_usb_audio_disconnect() kills all audio URBs. At the same time, the application, after being notified of the disconnection, might close the device, in which case ALSA calls the .hw_free callback, which should free the URBs too. Commit de1b8b93a0ba "[ALSA] Fix hang-up at disconnection of usb-audio" prevented snd_usb_hw_free() from freeing the URBs to avoid a hang that resulted from this race, but this introduced another race because the URB callbacks could now be executed after snd_usb_hw_free() has returned, and try to access already freed data. Fix the first race by introducing a mutex to serialize the disconnect callback and all PCM callbacks that manage URBs (hw_free and hw_params).

2011-02-22OMAP2/3: clock: fix fint calculation for DPLL_FREQSELJohn Ogness1-1/+1
In OMAP35X TRM Rev 2010-05 Figure 7-18 "DPLL With EMI Reduction Feature", it is shown that the internal frequency is calculated by CLK_IN/(N+1). However, the value passed to _dpll_test_fint() is already "N+1" since Linux is using the values to divide by. In the technical reference manual, "N" is referring to the divider's register value (0-127). During power management testing, it was observed that programming the wrong jitter correction value can cause the system to become unstable and eventually crash.

2011-02-23i2c-omap: Double clear of ARDY status in IRQ handlerRichard woodruff1-1/+5
This errata occurs when the ARDY interrupt generation is enabled. At the begining of every new transaction the ARDY interrupt is cleared. On continuous i2c transactions where after clearing the ARDY bit from I2C_STAT register (clearing the interrupt), the IRQ line is reasserted and the I2C_STAT[ARDY] bit set again on 1. In fact, the ARDY status bit is not cleared at the write access to I2C_STAT[ARDY] and only the IRQ line is deasserted and then reasserted. This is not captured in the usual errata documents. The workaround is to have a double clear of ARDY status in irq handler.

2011-02-22i2c-omap: fix static suspend vs. runtime suspendKevin Hilman1-0/+28
When runtime PM is enabled, each OMAP i2c device is suspended after each i2c xfer. However, there are two cases when the static suspend methods must be used to ensure the devices are suspended: 1) runtime PM is disabled, either at compile time or dynamically via /sys/devices/.../power/control. 2) an i2c client driver uses i2c during it's suspend callback, thus leaving the i2c driver active (NOTE: runtime suspend transitions are disabled during system suspend, so i2c activity during system suspend will runtime resume the device, but not runtime (re)suspend it.) Since the actual work to suspend the device is handled by the subsytem, call the bus methods to take care of it. NOTE: This takes care of a known suspend problem on OMAP3 where the TWL RTC driver does i2c xfers during its suspend path leaving the i2c driver in an active state (since runtime suspend transistions are disabled.)

irq_chip->irq_mask/unmask are called with interrupts disabled and irq_desc->lock held. So we cannot access i2c from this context. That's what irq_bus_sync_unlock() is for. Store the masked information in the chip data structure and update the i2c bus from the irq_bus_sync_unlock() callback. This does not need a while(pending) loop because the update to this is always serialized via the bus lock, so we never have more than one pin update pending.

Right now we, are relying on the fact that when we attempt to actually do the discard, blkdev_issue_discar() returns -EOPNOTSUPP and the user is informed that the device does not support discard. However, in the case where the we do not hit any suitable free extent to trim in FITRIM code, it will finish without any error. This is very confusing, because it seems that FITRIM was successful even though the device does not actually supports discard.

2011-02-22bridge: Use IPv6 link-local address for multicast listener queriesLinus Lüssing1-1/+2
Currently the bridge multicast snooping feature periodically issues IPv6 general multicast listener queries to sense the absence of a listener. For this, it uses :: as its source address - however RFC 2710 requires: "To be valid, the Query message MUST come from a link-local IPv6 Source Address". Current Linux kernel versions seem to follow this requirement and ignore our bogus MLD queries. With this commit a link local address from the bridge interface is being used to issue the MLD query, resulting in other Linux devices which are multicast listeners in the network to respond with a MLD response (which was not the case before).

2011-02-22bridge: Allow mcast snooping for transient link local addresses tooLinus Lüssing1-5/+4
Currently the multicast bridge snooping support is not active for link local multicast. I assume this has been done to leave important multicast data untouched, like IPv6 Neighborhood Discovery. In larger, bridged, local networks it could however be desirable to optimize for instance local multicast audio/video streaming too. With the transient flag in IPv6 multicast addresses we have an easy way to optimize such multimedia traffic without tempering with the high priority multicast data from well-known addresses. This patch alters the multicast bridge snooping for IPv6, to take effect for transient multicast addresses instead of non-link-local addresses.
