2009-10-29lis3: better support for hp 6730xPavel Herrmann
I have learned that the 6730b and 6730s have different accelerometer orientation, and have modified the driver accordingly (diff attached), while dropping the wild guess for AMD based 6735 having the same orientation as Intel based 6730 (this is not true for any other related series/family, thus is not probable for 673x).

2009-10-29cpuidle: always return with interrupts enabledKevin Hilman
In the case where cpuidle_idle_call() returns before changing state due to a need_resched(), it was returning with IRQs disabled. The idle path assumes that the platform specific idle code returns with interrupts enabled (although this too is undocumented AFAICT) and on ARM we have a WARN_ON(!(irqs_disabled()) when returning from the idle loop, so the user-visible effects were only a warning since interrupts were eventually re-enabled later. On x86, this same problem exists, but there is no WARN_ON() to detect it. As on ARM, the interrupts are eventually re-enabled, so I'm not sure of any actual bugs triggered by this. It's primarily a correctness/consistency fix. This patch ensures IRQs are (re)enabled before returning.

Allow csrows to properly initialize when the topology only has active channels on 2 and 3. This new check allows proper detection and initialization in this topology. Only checking the first mrt that represented channels 0 and 1 is not sufficient. I also fixed up the related debug information path. I can submit as a 2nd patch if needed.

2009-10-29edac: i5400 fix csrow mappingJeff Roberson
The i5400 EDAC driver has several bugs with chip-select row computation which most likely lead to bugs in detailed error reporting. Attempts to contact the authors have gone mostly unanswered so I am presenting my diff here. I do not subscribe to lkml and would appreciate being kept in the cc. The most egregious problem was miscalculating the addresses of MTR registers after register 0 by assuming they are 32bit rather than 16. This caused the driver to miss half of the memories. Most motherboards tend to have only 8 dimm slots and not 16, so this may not have been noticed before. Further, the row calculations multiplied the number of dimms several times, ultimately ending up with a maximum row of 32. The chipset only supports 4 dimms in each of 4 channels, so csrow could not be higher than 4 unless you use a row per-rank with dual-rank dimms. I opted to eliminate this behavior as it is confusing to the user and the error reporting works by slot and not rank. This gives a much clearer view of memory by slot and channel in /sys.

2009-10-29twl4030-gpio: remove __devexit markings from remove funcMike Frysinger
The gpio_twl4030_probe() function calls gpio_twl4030_remove(), and the former has __devinit, so the latter cannot use __devexit. Otherwise we hit the section mismatch warning: WARNING: drivers/gpio/built-in.o(.devinit.text+0x71a): Section mismatch in reference from the function _gpio_twl4030_probe() to the function .devexit.text:_gpio_twl4030_remove() The function __devinit _gpio_twl4030_probe() references a function __devexit _gpio_twl4030_remove(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __devexit annotation of _gpio_twl4030_remove() so it may be used outside an exit section.

Rusty, commit 3ca4f5ca73057a617f9444a91022d7127041970a virtio: add virtio IDs file moved all device IDs into a single file. While the change itself is a very good one, it can break userspace applications. For example if a userspace tool wanted to get the ID of virtio_net it used to include virtio_net.h. This does no longer work, since virtio_net.h does not include virtio_ids.h. This patch moves all "#include <linux/virtio_ids.h>" from the C files into the header files, making the header files compatible with the old ones. In addition, this patch exports virtio_ids.h to userspace.

2009-10-22virtio_blk: revert QUEUE_FLAG_VIRT additionChristoph Hellwig
It seems like the addition of QUEUE_FLAG_VIRT caueses major performance regressions for Fedora users: https://bugzilla.redhat.com/show_bug.cgi?id=509383 https://bugzilla.redhat.com/show_bug.cgi?id=505695 while I can't reproduce those extreme regressions myself I think the flag is wrong. Rationale: QUEUE_FLAG_VIRT expands to QUEUE_FLAG_NONROT which casus the queue unplugged immediately. This is not a good behaviour for at least qemu and kvm where we do have significant overhead for every I/O operations. Even with all the latested speeups (native AIO, MSI support, zero copy) we can only get native speed for up to 128kb I/O requests we already are down to 66% of native performance for 4kb requests even on my laptop running the Intel X25-M SSD for which the QUEUE_FLAG_NONROT was designed. If we ever get virtio-blk overhead low enough that this flag makes sense it should only be set based on a feature flag set by the host.

2009-10-20KS8851: Fix ks8851_set_rx_mode() for IFF_MULTICASTBen Dooks
In ks8851_set_rx_mode() the case handling IFF_MULTICAST was also setting the RXCR1_AE bit by accident. This meant that all unicast frames where being accepted by the device. Remove RXCR1_AE from this case. Note, RXCR1_AE was also masking a problem with setting the MAC address properly, so needs to be applied after fixing the MAC write order. Fixes a bug reported by Doong, Ping of Micrel. This version of the patch avoids setting RXCR1_ME for all cases. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: David S.

On this model, when KBD is in active multiplexing mode, acknowledgements to reset and get ID commands issued on KBD port sometimes are delivered to AUX3 port (touchpad) which messes up device detection. Legacy KBC mode works fine and since there are no external PS/2 ports on this laptop and no support for docking station we can safely disable active MUX mode. Tested-by: Carlos R.

vmxnet3 was using dprintk() for debugging output. This was defined in <linux/dst.h> and was the only thing that was used from that header file.

Allow the snapshot chunk size to be smaller than the page size The code is now capable of handling this due to some previous fixes and enhancements.

2009-10-16dm snapshot: sort by chunk size to fix raceMikulas Patocka
Avoid a race causing corruption when snapshots of the same origin have different chunk sizes by sorting the internal list of snapshots by chunk size, largest first. https://bugzilla.redhat.com/show_bug.cgi?id=182659 For example, let's have two snapshots with different chunk sizes. The first snapshot (1) has small chunk size and the second snapshot (2) has large chunk size. Let's have chunks A, B, C in these snapshots: snapshot1: ====A==== ====B==== snapshot2: ==========C========== (Chunk size is a power of 2. Chunks are aligned.) A write to the origin at a position within A and C comes along. It triggers reallocation of A, then reallocation of C and links them together using A as the 'primary' exception. Then another write to the origin comes along at a position within B and C. It creates pending exception for B. C already has a reallocation in progress and it already has a primary exception (A), so nothing is done to it: B and C are not linked. If the reallocation of B finishes before the reallocation of C, because there is no link with the pending exception for C it does not know to wait for it and, the second write is dispatched to the origin and causes data corruption in the chunk C in snapshot2. To avoid this situation, we maintain snapshots sorted in descending order of chunk size. This leads to a guaranteed ordering on the links between the pending exceptions and avoids the problem explained above - both A and B now get linked to C.
