2013-09-07s390/ftrace: avoid pointer arithmetics with function pointersHeiko Carstens
Pointer arithmetics with function pointers is not really defined, but seems to do the right thing. Let's cast to a void pointer to have a defined behaviour, at least when using gcc. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

2013-09-07um: Run UML in it's own session.Richard Weinberger
If UML is not run by a shell it can happen that UML will kill unrelated proceses upon a fatal exit because it issues a kill(0, ...). To prevent such oddities we create a new session in main().

2013-09-07um: Cleanup SIGTERM handlingRichard Weinberger
Richard reported that some UML processes survive if the UML main process receives a SIGTERM. This issue was caused by a wrongly placed signal(SIGTERM, SIG_DFL) in init_new_thread_signals(). It disabled the UML exit handler accidently for some processes. The correct solution is to disable the fatal handler for all UML helper threads/processes. Such that last_ditch_exit() does not get called multiple times and all processes can exit due to SIGTERM. Reported-and-tested-by: Richard W.M.

2013-09-07um: Implement probe_kernel_read()Richard Weinberger
UML needs it's own probe_kernel_read() to handle kernel mode faults correctly. The implementation uses mincore() on the host side to detect whether a page is owned by the UML kernel process. This fixes also a possible crash when sysrq-t is used. Starting with 3.10 sysrq-t calls probe_kernel_read() to read details from the kernel workers. As kernel worker are completely async pointers may turn NULL while reading them.

2013-09-07ACPI / hotplug / PCI: Use _OST to notify firmware about notify statusRafael J. Wysocki
The spec suggests that we should use _OST to notify the platform about the status of notifications it sends us, for example so that it doesn't repeate a notification that has been handled already. This turns out to help reduce the amount of diagnostic output from the ACPIPHP subsystem and speed up boot on at least one system that generates multiple device check notifies for PCIe devices on the root bus during boot.

2013-09-07ACPI / hotplug / PCI: Avoid doing too much for spurious notifiesRafael J. Wysocki
Sometimes we may get a spurious device check or bus check notify for a hotplug device and in those cases we should avoid doing all of the configuration work needed when something actually changes. To that end, check the return value of pci_scan_slot() in enable_slot() and bail out early if it is 0. This turns out to help reduce the amount of diagnostic output from the ACPIPHP subsystem and speed up boot on at least one system that generates multiple device check notifies for PCIe devices on the root bus during boot.

2013-09-06drm/i915: Delay disabling of VGA memory until vgacon->fbcon handoff is doneVille Syrjälä
When transitioning away from vgacon the system tries to save the current contents of the VGA memory, so that it can be cleanly handed off to fbcon (or whatever comes afterwards). The recent change commit 81b5c7bc8de3e6f63419139c2fc91bf81dea8a7d Author: Alex Williamson <alex.williamson@redhat.com> Date: Wed Aug 28 09:39:08 2013 -0600 i915: Update VGA arbiter support for newer devices caused i915 to disable VGA memory decode for the IGD when i915 is initializing. Unfortunately that happens before the vgacon->fbcon handoff so vgacon_save_screen() will read out all ones from the VGA memory. After the handoff fbcon will inherit the bogus state from vgacon, and pre-fills the fb with matching contents. The end result is a white rectangle in the top left corner of the screen, the size of which matches the now inactive VGA console. To remedy the situation delay the disabling of VGA memory until the vgacon->fbcon handoff has happened. Also rename i915_enable_vga to i915_enable_vga_mem to make the relationship between these functions clearer.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Olof Johansson: "This branch contains code cleanups, moves and removals for 3.12. There's a large number of various cleanups, and a nice net removal of 13500 lines of code. Highlights worth mentioning are: - A series of patches from Stephen Boyd removing the ARM local timer API. - Move of Qualcomm MSM IOMMU code to drivers/iommu. - Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver and switching over to the drivers/pwm one. - Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM). There's also a move of a header file out of include/linux/i2c/ to platform_data, where it really belongs. It touches mostly ARM platform code for include changes so we took it through our tree" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (83 commits) ARM: OMAP2+: Add back the define for AM33XX_RST_GLOBAL_WARM_SW_MASK gpio: (gpio-pca953x) move header to linux/platform_data/ arm: zynq: hotplug: Remove unreachable code ARM: SAMSUNG: Remove unnecessary exynos4_default_sdhci*() tegra: simplify use of devm_ioremap_resource ARM: SAMSUNG: Remove plat/regs-timer.h header ARM: SAMSUNG: Remove remaining uses of plat/regs-timer.h header ARM: SAMSUNG: Remove pwm-clock infrastructure ARM: SAMSUNG: Remove old PWM timer platform devices pwm: Remove superseded pwm-samsung-legacy driver ARM: SAMSUNG: Modify board files to use new PWM platform device ARM: SAMSUNG: Rework private data handling in dev-backlight pwm: Add new pwm-samsung driver ARM: mach-mvebu: remove redundant DT parsing and validation ARM: msm: Only compile io.c on platforms that use it iommu/msm: Move mach includes to iommu directory ARM: msm: Remove devices-iommu.c ARM: msm: Move mach/board.h contents to common.h ARM: msm: Migrate msm_timer to CLOCKSOURCE_OF_DECLARE ARM: msm: Remove TMR and TMR0 static mappings ...
