hwmon: (f75375s) Fix automatic pwm mode setting for F75373 & F75375

2012-02-20T20:48:12+00:00

commit 09e87e5c4f9af656af2a8a3afc03487c5d9287c3 upstream. In order to enable temperature mode aka automatic mode for the F75373 and F75375 chips, the two FANx_MODE bits in the fan configuration register need be set to 01, not 10. Signed-off-by: Nikolaus Schulz Signed-off-by: Greg Kroah-Hartman

gpio/pca953x: Fix warning of enabled interrupts in handler

2012-02-20T20:48:11+00:00

commit 6dd599f8af0166805951f4421a78ba716d78321a upstream. When using nested threaded irqs, use handle_nested_irq(). This function does not call the chip handler, so no handler is set.

net: fix NULL dereferences in check_peer_redir()

2012-02-13T19:06:13+00:00

[ Upstream commit d3aaeb38c40e5a6c08dd31a1b64da65c4352be36, along with dependent backports of commits: 69cce1d1404968f78b177a0314f5822d5afdbbfb 9de79c127cccecb11ae6a21ab1499e87aa222880 218fa90f072e4aeff9003d57e390857f4f35513e 580da35a31f91a594f3090b7a2c39b85cb051a12 f7e57044eeb1841847c24aa06766c8290c202583 e049f28883126c689cf95859480d9ee4ab23b7fa ] Gergely Kalman reported crashes in check_peer_redir(). It appears commit f39925dbde778 (ipv4: Cache learned redirect information in inetpeer.) added a race, leading to possible NULL ptr dereference. Since we can now change dst neighbour, we should make sure a reader can safely use a neighbour. Add RCU protection to dst neighbour, and make sure check_peer_redir() can be called safely by different cpus in parallel. As neighbours are already freed after one RCU grace period, this patch should not add typical RCU penalty (cache cold effects) Many thanks to Gergely for providing a pretty report pointing to the bug.

powernow-k8: Fix indexing issue

2012-02-13T19:06:13+00:00

commit a8eb28480e9b637cc78b9aa5e08612ba97e1317a upstream. The driver uses the pstate number from the status register as index in its table of ACPI pstates (powernow_table). This is wrong as this is not a 1-to-1 mapping. For example we can have _PSS information to just utilize Pstate 0 and Pstate 4, ie. powernow-k8: Core Performance Boosting: on. powernow-k8: 0 : pstate 0 (2200 MHz) powernow-k8: 1 : pstate 4 (1400 MHz) In this example the driver's powernow_table has just 2 entries. Using the pstate number (4) as index into this table is just plain wrong. Signed-off-by: Andreas Herrmann Signed-off-by: Dave Jones Signed-off-by: Greg Kroah-Hartman

powernow-k8: Avoid Pstate MSR accesses on systems supporting CPB

2012-02-13T19:06:13+00:00

commit 201bf0f129e1715a33568d1563d9a75b840ab4d3 upstream. Due to CPB we can't directly map SW Pstates to Pstate MSRs. Get rid of the paranoia check. (assuming that the ACPI Pstate information is correct.) Signed-off-by: Andreas Herrmann Signed-off-by: Dave Jones Signed-off-by: Greg Kroah-Hartman

USB: add new zte 3g-dongle's pid to option.c

2012-02-13T19:06:13+00:00

commit 1608ea5f4b5d6262cd6e808839491cfb2a67405a upstream. As ZTE have and will use more pid for new products this year, so we need to add some new zte 3g-dongle's pid on option.c , and delete one pid 0x0154 because it use for mass-storage port.
