2010-01-06Input: atkbd - add force relese key quirk for Samsung R59P/R60P/R61PMoiseev Vladimir
This patch is not upstream. Since 2.6.32, there is an interface in /sys for handling the force_release events from userspace, so such quirk patches are no longer accepted upstream now. But this patch is valid for version 2.6.31 downwards.

2010-01-06rt2x00: Disable powersaving for rt61pci and rt2800pci.Gertjan van Wingerde
commit 93b6bd26b74efe46b4579592560f9f1cb7b61994 upstream. We've had many reports of rt61pci failures with powersaving enabled. Therefore, as a stop-gap measure, disable powersaving of the rt61pci until we have found a proper solution. Also disable powersaving on rt2800pci as it most probably will show the same problem.

2010-01-06S390: dasd: support DIAG access for read-only devicesStefan Weinhuber
commit 22825ab7693fd29769518a0d25ba43c01a50092a upstream. When a DASD device is used with the DIAG discipline, the DIAG initialization will indicate success or error with a respective return code. So far we have interpreted a return code of 4 as error, but it actually means that the initialization was successful, but the device is read-only. To allow read-only devices to be used with DIAG we need to accept a return code of 4 as success. Re-initialization of the DIAG access is also part of the DIAG error recovery. If we find that the access mode of a device has been changed from writable to read-only while the device was in use, we print an error message.

2010-01-06hostap: Revert a toxic part of the conversion to net_device_opsMartin Decky
commit e484c16f6212f7f06407382efa4d3ad214b6c589 upstream. As the hostap driver was converted to use net_device_ops, a mistake was made in hostap_main.c (commit 5ae4efbcd2611562a8b93596be034e63495706a5). Originally, the tx_queue_len was set to 0 for every other interface than HOSTAP_INTERFACE_MASTER, but the new fragment of code sets tx_queue_len to 0 only for HOSTAP_INTERFACE_MASTER. The opposite of the previous behavior makes the driver to drop all packets in AP mode. Change the way 0 is assigned to tx_queue_len according to the original logic.

commit ac06c06770bb8761b1f1f9bdf2f5420fa6d3e9fa upstream. While converting emi62 to use request_firmware(), the driver was also changed to use the ihex helper functions. However, this broke the loading of the FPGA firmware because the code tries to access the addr field of the EOF record which works with a plain array that has an empty last record but not with the ihex helper functions where the end of the data is signaled with a NULL record pointer, resulting in: BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<f80d248c>] emi62_load_firmware+0x33c/0x740 [emi62] This can be fixed by changing the loop condition to test the return value of ihex_next_binrec() directly (like in emi26.c).

commit 256ace9bbd4cdb6d48d5f55d55d42fa20527fad1 upstream. The clock turnaround code still doesn't work for several reasons: - 'USE_DPLL' flag in 'ap->host->private_data' is never initialized or updated, so the driver can only set the chip to the DPLL clock mode, not the PCI mode; - the driver doesn't serialize access to the channels depending on the current clock mode like the vendor drivers, so the clock turnaround is only executed "optionally", not always as it should be; - the wrong ports are written to when hpt3x2n_set_clock() is called for the secondary channel; - hpt3x2n_set_clock() can inadvertently enable the disabled channels when resetting the channel state machines.

commit 509426bd46ad0903dca409803e0ee3d30f99f1e8 upstream. adev->dma_mode stores the transfer mode value not UDMA mode number so the condition in cmd64x_set_dmamode() is always true and the higher UDMA clock is always selected. This can potentially result in data corruption when UDMA33 device is used, when 40-wire cable is used or when the error recovery code decides to lower the device speed down. The issue was introduced in the commit 6a40da0 ("libata cmd64x: whack into a shape that looks like the documentation") which goes back to kernel 2.6.20.

2010-01-06md: Fix unfortunate interaction with evmsNeilBrown
commit cbd1998377504df005302ac90d49db72a48552a6 upstream. evms configures md arrays by: open device send ioctl close device for each different ioctl needed. Since 2.6.29, the device can disappear after the 'close' unless a significant configuration has happened to the device. The change made by "SET_ARRAY_INFO" can too minor to stop the device from disappearing, but important enough that losing the change is bad. So: make sure SET_ARRAY_INFO sets mddev->ctime, and keep the device active as long as ctime is non-zero (it gets zeroed with lots of other things when the array is stopped). This is suitable for -stable kernels since 2.6.29. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

commit 45b241689179a6065384260242637cf21dabfb2d upstream. The libertas driver copies the SSID buffer back to the wireless core and appends a trailing NULL character for termination. This is a) unnecessary because the buffer is allocated with kzalloc and is hence already NULLed when this function is called, and b) for priv->curbssparams.ssid_len == 32, it writes back one byte too much which causes memory corruptions.

2009-12-18powerpc/therm_adt746x: Record pwm invert bit at module load time]Darrick J. Wong
commit 1496e89ae2a0962748e55165a590fa3209c6f158 upstream. In commit 0512a9a8e277a9de2820211eef964473b714ae65, we unilaterally zero the "pwm invert" bit in the fan behavior configuration register. On my PowerBook G4, this results in the fans going to full speed at low temperature and shutting off at high temperature because the pwm invert bit is supposed to be set. Therefore, record the pwm invert bit at driver load time, and write the bit into the fan behavior control register. This restores correct behavior on my PBG4 and should work around the bit being set to the wrong value after suspend/resume (which is what the original patch was trying to fix). It also fixes a minor omission where the pwm invert bit correction is NOT performed when switching into automatic mode. Signed-off-by: Darrick J.

2009-12-18thinkpad-acpi: preserve rfkill state across suspend/resumeHenrique de Moraes Holschuh
commit 208b996b6c460285650d39b2330f8ef82c007d10 upstream. Since the rfkill rework in 2.6.31, the driver is always resuming with the radios disabled. Change thinkpad-acpi to ask the firmware to resume with the radios in the last state. This fixes the Bluetooth and WWAN rfkill switches. Note that it means we respect the firmware's oddities. Should the user toggle the hardware rfkill switch on and off, it might cause the radios to resume enabled. UWB is an unknown quantity since it has nowhere the same level of firmware support (no control over state storage in NVRAM, for example), and might need further fixing. Testers welcome. This change fixes a regression from 2.6.30.

2009-12-18thinkpad-acpi: fix default brightness_mode for R50e/R51Henrique de Moraes Holschuh
commit a9f8eacca4e9e8693de9b896c1fa7aadaa9402e8 upstream. According to a report, the R50e wants EC-based brightness control, even if it uses an Intel GPU. The current driver default was reported to not work at all. This bug can be worked around by the "brightness_mode=3" module parameter. Change the default of the R50e and R51 2xxx models (which use the same EC firmware, 1V) to TPACPI_BRGHT_Q_EC, but keep TPACPI_BRGHT_Q_ASK set for now, as I'd like to get more reports. This fixes a regression caused by commit 59fe4fe34d7afdf63208124f313be9056feaa2f4, "thinkpad-acpi: fix incorrect use of TPACPI_BRGHT_MODE_ECNVRAM" Kernel 2.6.31 also needs this fix.

Origin code only marks both blue and green channel case as connected, but ignore other possible connected states. This one trys to detect CRT by checking no channel attached case instead.

2009-12-18drm/i915: Avoid NULL dereference with component_only tv_modesChris Wilson
commit d271817baecbccb47da0d9f28c285a0dae8a06b7 upstream. In commit d2d9f2324, the guard for a valid video mode was removed. This caused the regression: kernel crash during kms graphic boot on Intel GM4500 platform https://bugzilla.redhat.com/show_bug.cgi?id=540218 This patches changes the logic slightly not to rely on a coupled variable, but to just check whether the video_modes is valid before dereferencing.

2009-12-18b43legacy: avoid PPC fault during resumeLarry Finger
commit 316a4d966cae3c2dec83ebb1ee1a3515f97b30ff upstream. For PPC architecture with PHY Revision < 3, a read of the register B43_MMIO_HWENABLED_LO will cause a CPU fault unless b43legacy_status() returns a value of 2 (B43legacy_STAT_STARTED); however, one finds that the driver is unable to associate after resuming from hibernation unless this routine returns 1. To satisfy both conditions, the routine is rewritten to return TRUE whenever b43legacy_status() returns a value < 2.

[ Upstream commit 457931de3b0925dc2eb941bc7d611a509be36dff ] RSC and LOM devices have fixed speed settings. We already had some code to match and handle "rsc" named devices on E250 systems, but we also have to handle 'rsc-console', 'rsc-control', and 'lom-console'. Also, in order to get this right regardless of what 'output-device' happens to be, explicitly pass the UART device node pointer to this routine. Signed-off-by: David S.

This is going to be used in the SU driver for rsc-console detection. There is probably a better way to handle this, but this is the least intrusive solution for now which we can validate won't break any other cases. Signed-off-by: David S.

2009-12-18NET: smc91x: Fix irq flagsRussell King - ARM Linux
[ Upstream commit d5ccd67bb77ced5249067d05171992a7d5020393 ] smc91x.h defines SMC_IRQ_FLAGS to be -1 when it wants the interrupt flags to be taken from the resource structure. However, d280ead changed this to checking for non-zero resource flags. Unfortunately, this means that on some platforms, we end up passing '-1' to request_irq rather than the desired result. Combine the two conditions into one so that the IRQ flags are taken from the resource if either SMC_IRQ_FLAGS is -1 or the resource flags specify an interrupt trigger.

2009-12-18b44 WOL setup: one-bit-off stack corruption kernel panic fixStanislav Brabec
[ Upstream commit: e0188829cb724e7d12a2d4e343b368ff1d6e1471 ] About 50% of shutdowns of b44 Ethernet adapter ends by kernel panic with kernels compiled with stack-protector. Checking b44_magic_pattern() return values, one call of b44_magic_pattern() returns 127. It means, that set_bit(128, pmask) was called on line 1509. It means that bit 0 of 17th byte of pmask was overwritten. But pmask has only 16 bytes. Stack corruption happens. It seems that set_bit() on line 1509 always writes one bit off. The fix does not only solve the stack corruption, but also makes Wake On LAN working on my onboard B44 on Asus A7V-333X mainboard. It seems that this problem affects all kernel versions since commit 725ad800 ([PATCH] b44: add wol for old nic) on 2006-06-20.
