2015-02-03ti-st: clean up data types (fix harmless memory corruption)Dan Carpenter2-12/+12
The big issue here is: of_property_read_u32(np, "flow_cntrl", (u32 *)&dt_pdata->flow_cntrl); "->flow_cntrl" is a char so when we write a 32 bit number to it then it corrupts past the end of the char. It's probably hard to notice because the struct has padding so the code works on little endian systems. But on a big endian system the code would fail and on a 64 bit, big endian systems then "nshutdown_gpio" and "baud_rate" would be buggy as well.

2015-01-25Drivers: hv: vmbus: serialize Offer and Rescind offerVitaly Kuznetsov1-8/+22
Commit 4b2f9abea52a ("staging: hv: convert channel_mgmt.c to not call osd_schedule_callback")' was written under an assumption that we never receive Rescind offer while we're still processing the initial Offer request. However, the issue we fixed in 04a258c162a8 could be caused by this assumption not always being true. In particular, we need to protect against the following: 1) Receiving a Rescind offer after we do queue_work() for processing an Offer request and before we actually enter vmbus_process_offer(). work.func points to vmbus_process_offer() at this moment and in vmbus_onoffer_rescind() we do another queue_work() without a check so we'll enter vmbus_process_offer() twice. 2) Receiving a Rescind offer after we enter vmbus_process_offer() and especially after we set >state = CHANNEL_OPEN_STATE. Many things can go wrong in that case, e.g. we can call free_channel() while we're still using it. Implement the required protection by changing work->func at the very end of vmbus_process_offer() and checking work->func in vmbus_onoffer_rescind(). In case we receive rescind offer during or before vmbus_process_offer() is done we set rescind flag to true and we check it at the end of vmbus_process_offer() so such offer will not get lost.

2015-01-25VMCI: Fix two UVA mapping bugsJorgen Hansen2-7/+8
(this is a resend of this patch. Originally sent last year, but post appears to have been lost) This change fixes two bugs in the VMCI host driver related to mapping the notify boolean from user space into kernel space: - the actual UVA was rounded up to the next page boundary - resulting in memory corruption in the calling process whenever notifications would be signalled. This has been fixed by just removing the PAGE_ALIGN part, since get_user_pages_fast can figure this out on its own - the mapped page wasn't stored anywhere, so it wasn't unmapped and put back when a VMCI context was destroyed. Fixed this by remembering the page.

2015-01-25misc: ti-st: add handling of the signal caseNicholas Mc Guire1-8/+11
if(!wait_for_completion_interruptible_timeout(...)) only handles the timeout case - this patch adds handling the signal case the same as timeout. Only the timeout case was being handled, the signal case (-ERESTARTSYS) was treated just like the case of successful completion, which is most likely not reasonable. read_local_version() is called from download_firmware() where it checks for !=0 return, so the error handling logic should be preserved correctly. download_firmware() is called from st_kim_start() which is checking for !=0 return, so the error handling logic should be preserved correctly Signed-off-by: Nicholas Mc Guire <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

This patch adds new function i8k_get_fan_nominal_speed() for doing SMM call which will return nominal fan RPM for specified fan speed. It returns nominal RPM value at which fan operate when speed (0, 1, 2, 3) is set. It looks like RPM value is not accurate, but still provides very useful information. New function i8k_get_fan_nominal_speed() is used for determinate if fan multiplier is 1 or 30. If function for maximal fan value success and returned RPM value too high (above 30000) then fan multiplier is set to 1. Otherwise multiplier is not changed and default value 30 is used.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes from Olof Johansson: "We've been sitting on our fixes branch for a while, so this batch is unfortunately on the large side. A lot of these are tweaks and fixes to device trees, fixing various bugs around clocks, reg ranges, etc. There's also a few defconfig updates (which are on the late side, no more of those). All in all the diffstat is bigger than ideal at this time, but nothing in here seems particularly risky" * tag 'armsoc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (31 commits) reset: sunxi: fix spinlock initialization ARM: dts: disable CCI on exynos5420 based arndale-octa drivers: bus: check cci device tree node status ARM: rockchip: disable jtag/sdmmc autoswitching on rk3288 ARM: nomadik: fix up leftover device tree pins ARM: at91: board-dt-sama5: add phy_fixup to override NAND_Tree ARM: at91/dt: sam9263: Add missing clocks to lcdc node ARM: at91: sama5d3: dt: correct the sound route ARM: at91/dt: sama5d4: fix the timer reg length ARM: exynos_defconfig: Enable LM90 driver ARM: exynos_defconfig: Enable options for display panel support arm: dts: Use pmu_system_controller phandle for dp phy ARM: shmobile: sh73a0 legacy: Set .control_parent for all irqpin instances ARM: dts: berlin: correct BG2Q's SM GPIO location.
