2011-07-11dlm: don't do pointless NULL check, use kzalloc and fix order of argumentsJesper Juhl
In fs/dlm/lock.c in the dlm_scan_waiters() function there are 3 small issues: 1) There's no need to test the return value of the allocation and do a memset if is succeedes. Just use kzalloc() to obtain zeroed memory. 2) Since kfree() handles NULL pointers gracefully, the test of 'warned' against NULL before the kfree() after the loop is completely pointless. Remove it. 3) The arguments to kmalloc() (now kzalloc()) were swapped. Thanks to Dr. David Alan Gilbert for pointing this out.

2011-06-29ahci: change 'masking port_map' printk to KERN_WARNING levelLinus Torvalds
It's not so much an error as a warning about normal Marvell crazines. So don't use KERN_ERR that ends up spamming the console even in quiet mode, it's not _that_ critical. Explained by Jeff: "Long explanation, it's a mess: Marvell took standard AHCI, and bastardized it to include a weird mode whereby PATA devices appear inside the AHCI DMA and interrupt infrastructure you're familiar with. So, PATA devices appear via pata_marvell driver, using basic legacy IDE programming interface. But SATA devices, which might also be attached to this chip, either work in under-performing mode or simply don't work at all (e.g. newer 6 Gbps devices or port multiplier attachments, NCQ, ...) On the other hand, 'ahci' driver loads and works with the chip's attached SATA devices quite beautifully, but is completely unable to drive any attached PATA devices, due to the Marvell-specific PATA-under-AHCI interface. The "masking port_map 0x7 -> 0x3" message is the ahci driver "hiding" the PATA port(s) from itself, making sure it will only drive the SATA ports it knows how to drive."

2011-06-29netfilter: Fix ip_route_me_harder triggering ip_rt_bugJulian Anastasov
Avoid creating input routes with ip_route_me_harder. It does not work for locally generated packets. Instead, restrict sockets to provide valid saddr for output route (or unicast saddr for transparent proxy). For other traffic allow saddr to be unicast or local but if callers forget to check saddr type use 0 for the output route. The resulting handling should be: - REJECT TCP: - in INPUT we can provide addr_type = RTN_LOCAL but better allow rejecting traffic delivered with local route (no IP address => use RTN_UNSPEC to allow also RTN_UNICAST). - FORWARD: RTN_UNSPEC => allow RTN_LOCAL/RTN_UNICAST saddr, add fix to ignore RTN_BROADCAST and RTN_MULTICAST - OUTPUT: RTN_UNSPEC - NAT, mangle, ip_queue, nf_ip_reroute: RTN_UNSPEC in LOCAL_OUT - IPVS: - use RTN_LOCAL in LOCAL_OUT and FORWARD after SNAT to restrict saddr to be local Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: David S.

2011-06-29i2c/pca954x: Initialize the mux to disconnected statePetri Gynther
pca954x power-on default is channel 0 connected. If multiple pca954x muxes are connected to the same physical I2C bus, the parent bus will see channel 0 devices behind both muxes by default. This is bad. Scenario: -- pca954x @ 0x70 -- ch 0 (I2C-bus-101) -- EEPROM @ 0x50 | I2C-bus-1 --- | -- pca954x @ 0x71 -- ch 0 (I2C-bus-111) -- EEPROM @ 0x50 1. Load I2C bus driver: creates I2C-bus-1 2. Load pca954x driver: creates virtual I2C-bus-101 and I2C-bus-111 3. Load eeprom driver 4. Try to read EEPROM @ 0x50 on I2C-bus-101. The transaction will also bleed onto I2C-bus-111 because pca954x @ 0x71 channel 0 is connected by default.

2011-06-28drm/i915: forcewake fix after resetBen Widawsky
The failure is as follows: 1. Userspace gets forcewake lock, lock count >=1 2. GPU hang/reset occurs (forcewake bit is reset) 3. count is now incorrect The failure can only occur when using the forcewake userspace lock. This has the unfortunate consequence of messing up the driver as well as userspace, unless userspace closes the debugfs file, the kernel will never end up waking the GT since the refcount will be > 1. The solution is to try to recover the correct forcewake state based on the refcount. There is a period of time where userspace reads/writes may occur after the reset, before the GT has been forcewaked. The interface was never designed to be a perfect solution for userspace reads/writes, and the kernel portion is fixed by this patch.

2011-06-28watchdog: mtx1-wdt: fix GPIO togglingFlorian Fainelli
Commit e391be76 (MIPS: Alchemy: Clean up GPIO registers and accessors) changed the way the GPIO was toggled. Prior to this patch, we would always actively drive the GPIO output to either 0 or 1, this patch drove the GPIO active to 0, and put the GPIO in tristate to drive it to 1, unfortunately this does not work, revert back to active driving. Using a signed variable (gstate) to hold the gpio state and using a bit- wise operation on it also resulted in toggling value from 1 to -2 since the variable is signed. This value was then passed on to gpio_direction_ output, which always perform a if (value) ... to set the value to the gpio, so we were always writing a 1 to this GPIO instead of 1 -> 0 -> 1 ...
