2012-03-22ceph: fix overflow check in build_snap_context()Xi Wang
The overflow check for a + n * b should be (n > (ULONG_MAX - a) / b), rather than (n > ULONG_MAX / b - a). Signed-off-by: Xi Wang <xi.wang@gmail.com> Signed-off-by: Sage Weil <sage@newdream.net>
2012-03-22libceph: fix overflow check in crush_decode()Xi Wang
The existing overflow check (n > ULONG_MAX / b) didn't work, because n = ULONG_MAX / b would both bypass the check and still overflow the allocation size a + n * b. The correct check should be (n > (ULONG_MAX - a) / b). Signed-off-by: Xi Wang <xi.wang@gmail.com> Signed-off-by: Sage Weil <sage@newdream.net>

2012-03-22net/ceph: Only clear SOCK_NOSPACE when there is sufficient space in the ↵Jim Schutt
socket buffer The Ceph messenger would sometimes queue multiple work items to write data to a socket when the socket buffer was full. Fix this problem by making ceph_write_space() use SOCK_NOSPACE in the same way that net/core/stream.c:sk_stream_write_space() does, i.e., clearing it only when sufficient space is available in the socket buffer.

2012-03-22xen: initialize platform-pci even if xen_emul_unplug=neverIgor Mammedov
When xen_emul_unplug=never is specified on kernel command line reading files from /sys/hypervisor is broken (returns -EBUSY). It is caused by xen_bus dependency on platform-pci and platform-pci isn't initialized when xen_emul_unplug=never is specified.

2012-03-22toshiba_acpi: Support alternate hotkey interfacesSeth Forshee
There are two types of problems that prevent hotkeys from working on many of the machines supported by toshiba_acpi. The first of these is the lack of a functioning SCI for hotkey events. For these machines it is possible to filter the Fn keypresses from the keyboard and generate a notification by executing the ACPI NTFY method. The second problem is a lack of support for HCI_SYSTEM_EVENT, which is used for reading the hotkey scancodes. On these machines the scancodes can be read by executing the ACPI NTFY method. This patch fixes both problems by installing an i8042 filter when the NTFY method is present to generate notifications and by detecting which of INFO or HCI_SYSTEM_EVENT is supported for reading scancodes. If neither method of reading scancodes is supported, the hotkey input device is not registered.

2012-03-22mfd: Make twl4030 SIH SPARSE_IRQ capableBenoit Cousson
twl4030 is using a two level irq controllers infrastruture. So far, only the first level was using dynamic irq_desc allocation to be able to have irq_domain support for device tree. There is a need to allocate separate irq_descs for the SIH too to avoid hacking the first level with interrupts from the second level. Add an irq_base parameter to allow the caller to provide the base from pdata or from dynamic allocation. Affect TWL4030_NR_IRQS to the twl-core IRQs only. Moreover that will allow the extraction of the of_node pointer for further Device Tree conversion.

2012-03-22mfd: Move twl-core IRQ allocation into twl[4030|6030]-irq filesBenoit Cousson
During DT adaptation, the irq_alloc_desc was added into twl-core, but due to the rather different and weird IRQ management required by the twl4030, it is much better to have a different approach for it. The issue is that twl4030 uses a two level IRQ mechanism but handles all the PWR interrupts as part of the twl-core interrupt range. It ends up with a range of 16 interrupts total for CORE and PWR. The other twl4030 functionalities already have a dedicated driver and thus their IRQs and irqdomain can and should be defined localy. twl6030 is using a single level IRQ controller and thus does not require any trick. Move the irq_alloc_desc and irq_domain_add_legacy in twl4030-irq and twl6030-irq. Allocate together CORE and PWR IRQs for twl4030-irq.

2012-03-21tg3: Fix RSS ring refill race conditionMichael Chan
The RSS feature in tg3 hardware has only one rx producer ring for all RSS rings. NAPI vector 1 is special and handles the refilling of the rx producer ring on behalf of all RSS rings. There is a race condition between these RSS NAPIs and the NAPI[1]. If NAPI[1] finishes checking for refill and then another RSS ring empties the rx producer ring before NAPI[1] exits NAPI, the chip will be completely out of SKBs in the rx producer ring. We fix this by adding a flag tp->rx_refill and rely on napi_schedule()/ napi_complete() to help synchronize it to close the race condition. Update driver version to 3.123.

It is going to be a bit more nasty than usual as in touching things outside of arch/powerpc mostly due to the big iSeriesectomy :-) We finally got rid of the bugger (legacy iSeries support) which was a PITA to maintain and that nobody really used anymore. Here are some of the highlights: - Legacy iSeries is gone. Thanks Stephen ! There's still some bits and pieces remaining if you do a grep -ir series arch/powerpc but they are harmless and will be removed in the next few weeks hopefully. - The 'fadump' functionality (Firmware Assisted Dump) replaces the previous (equivalent) "pHyp assisted dump"... it's a rewrite of a mechanism to get the hypervisor to do crash dumps on pSeries, the new implementation hopefully being much more reliable. Thanks Mahesh Salgaonkar. - The "EEH" code (pSeries PCI error handling & recovery) got a big spring cleaning, motivated by the need to be able to implement a new backend for it on top of some new different type of firwmare. The work isn't complete yet, but a good chunk of the cleanups is there. Note that this adds a field to struct device_node which is not very nice and which Grant objects to. I will have a patch soon that moves that to a powerpc private data structure (hopefully before rc1) and we'll improve things further later on (hopefully getting rid of the need for that pointer completely). Thanks Gavin Shan. - I dug into our exception & interrupt handling code to improve the way we do lazy interrupt handling (and make it work properly with "edge" triggered interrupt sources), and while at it found & fixed a wagon of issues in those areas, including adding support for page fault retry & fatal signals on page faults. - Your usual random batch of small fixes & updates, including a bunch of new embedded boards, both Freescale and APM based ones, etc..."
