2013-04-07KVM: s390: virtio_ccw: reset errors for new I/O.Cornelia Huck
ccw_io_helper neglected to reset vcdev->err after a new channel program had been successfully started, resulting in stale errors delivered after one I/O failed. Reset the error after a new channel program has been successfully started with no old I/O pending.

2013-04-02KVM: s390: Change the virtual memory mapping location for virtio devicesNick Wang
The current location for mapping virtio devices does not take into consideration the standby memory. This causes the failure of mapping standby memory since the location for the mapping is already taken by the virtio devices. To fix the problem, we move the location to beyond the end of standby memory.

2013-03-19PCI: Use ROM images from firmware only if no other ROM source availableMatthew Garrett
Mantas Mikulėnas reported that his graphics hardware failed to initialise after commit f9a37be0f02a ("x86: Use PCI setup data"). The aim of this commit was to ensure that ROM images were available on some Apple systems that don't expose the GPU ROM via any other source. In this case, UEFI appears to have provided a broken ROM image that we were using even though there was a perfectly valid ROM available via other sources. The simplest way to handle this seems to be to just re-order pci_map_rom() and leave any firmare-supplied ROM to last.

2013-03-17net: cdc_ncm, cdc_mbim: allow user to prefer NCM for backwards compatibilityBjørn Mork
commit bd329e1 ("net: cdc_ncm: do not bind to NCM compatible MBIM devices") introduced a new policy, preferring MBIM for dual NCM/MBIM functions if the cdc_mbim driver was enabled. This caused a regression for users wanting to use NCM. Devices implementing NCM backwards compatibility according to section 3.2 of the MBIM v1.0 specification allow either NCM or MBIM on a single USB function, using different altsettings. The cdc_ncm and cdc_mbim drivers will both probe such functions, and must agree on a common policy for selecting either MBIM or NCM. Until now, this policy has been set at build time based on CONFIG_USB_NET_CDC_MBIM. Use a module parameter to set the system policy at runtime, allowing the user to prefer NCM on systems with the cdc_mbim driver.

2013-03-15Merge at91 lcdfb bug fixes into fixesArnd Bergmann
These are part of a longer series that has been submitted some time ago for the frame buffer tree, but it was never accepted there. The first two of the five patches are bug fixes, so let's merge this through arm-soc to get a working 3.9 kernel for at91. * commit '67cf9c0a': ARM: at91: fix LCD-wiring mode atmel_lcdfb: fix 16-bpp modes on older SOCs Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2013-03-14input/joystick: use get_cycles on ARMArnd Bergmann
ARM normally has an accurate clock source, so we can theoretically use analog joysticks more accurately and at the same time avoid the build warning #warning Precise timer not defined for this architecture. from the joystick driver. Now, why anybody would use that driver no ARM I have no idea, but Ben Dooks enabled it in the s3c2410_defconfig along with a bunch of other drivers, even though that platform has neither ISA nor PCI support. It still seems to be the right thing to fix this quirk.

2013-03-14clk: vt8500: Fix "fix device clock divisor calculations"Arnd Bergmann
Patch 72480014b8 "Fix device clock divisor calculations" was apparently rebased incorrectly before it got upstream, causing a build error. Replacing the "prate" pointer with the local parent_rate is most likely the correct solution.

2013-03-14hwmon: (pmbus/ltc2978) Fix temperature reportingGuenter Roeck
On LTC2978, only READ_TEMPERATURE is supported. It reports the internal junction temperature. This register is unpaged. On LTC3880, READ_TEMPERATURE and READ_TEMPERATURE2 are supported. READ_TEMPERATURE is paged and reports external temperatures. READ_TEMPERATURE2 is unpaged and reports the internal junction temperature.

2013-03-14mtd: nand: reintroduce NAND_NO_READRDY as NAND_NEED_READRDYBrian Norris
This partially reverts commit 1696e6bc2ae83734e64e206ac99766ea19e9a14e ("mtd: nand: kill NAND_NO_READRDY"). In that patch I overlooked a few things. The original documentation for NAND_NO_READRDY included "True for all large page devices, as they do not support autoincrement." I was conflating "not support autoincrement" with the NAND_NO_AUTOINCR option, which was in fact doing nothing. So, when I dropped NAND_NO_AUTOINCR, I concluded that I then could harmlessly drop NAND_NO_READRDY. But of course the fact the NAND_NO_AUTOINCR was doing nothing didn't mean NAND_NO_READRDY was doing nothing... So, NAND_NO_READRDY is re-introduced as NAND_NEED_READRDY and applied only to those few remaining small-page NAND which needed it in the first place.

2013-03-13tidspbridge: convert to idr_alloc()Tejun Heo
idr_get_new*() and friends are about to be deprecated. Convert to the new idr_alloc() interface. There are some peculiarities and possible bugs in the converted functions. This patch preserves those. * drv_insert_node_res_element() returns -ENOMEM on alloc failure, -EFAULT if id space is exhausted. -EFAULT is at best misleading. * drv_proc_insert_strm_res_element() is even weirder. It returns -EFAULT if kzalloc() fails, -ENOMEM if idr preloading fails and -EPERM if id space is exhausted. What's going on here? * drv_proc_insert_strm_res_element() doesn't free *pstrm_res after failure. Only compile tested.
