PV console, block and network frontend/backends are working. Bug-fixes: * Fix compile linux-next fallout. * Fix PVHVM bootup crashing. The Xen-unstable hypervisor (so will be 4.3 in a ~6 months), supports ARMv7 platforms. The goal in implementing this architecture is to exploit the hardware as much as possible. That means use as little as possible of PV operations (so no PV MMU) - and use existing PV drivers for I/Os (network, block, console, etc). This is similar to how PVHVM guests operate in X86 platform nowadays - except that on ARM there is no need for QEMU. The end result is that we share a lot of the generic Xen drivers and infrastructure. Details on how to compile/boot/etc are available at this Wiki: http://wiki.xen.org/wiki/Xen_ARMv7_with_Virtualization_Extensions and this blog has links to a technical discussion/presentations on the overall architecture: http://blog.xen.org/index.php/2012/09/21/xensummit-sessions-new-pvh-virtualisation-mode-for-arm-cortex-a15arm-servers-and-x86/ * tag 'stable/for-linus-3.7-arm-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: (21 commits) xen/xen_initial_domain: check that xen_start_info is initialized xen: mark xen_init_IRQ __init xen/Makefile: fix dom-y build arm: introduce a DTS for Xen unprivileged virtual machines MAINTAINERS: add myself as Xen ARM maintainer xen/arm: compile netback xen/arm: compile blkfront and blkback xen/arm: implement alloc/free_xenballooned_pages with alloc_pages/kfree xen/arm: receive Xen events on ARM xen/arm: initialize grant_table on ARM xen/arm: get privilege status xen/arm: introduce CONFIG_XEN on ARM xen: do not compile manage, balloon, pci, acpi, pcpu and cpu_hotplug on ARM xen/arm: Introduce xen_ulong_t for unsigned long xen/arm: Xen detection and shared_info page mapping docs: Xen ARM DT bindings xen/arm: empty implementation of grant_table arch specific functions xen/arm: sync_bitops xen/arm: page.h definitions xen/arm: hypercalls ...

Standard behavior with fs.suid_dumpable = 2 is to create core file with uid=gid=0. However, there was no way for coredump handler to know that the process being dumped was suid'ed. This patch adds the new %d specifier for format_corename() which simply reports __get_dumpable(mm->flags), this is compatible with /proc/sys/fs/suid_dumpable we already have.

Drivers are also gradually getting Device Tree and IRQ domain support. The following drivers got DT support: - palmas, 88pm860x, tc3589x and twl4030-audio And those ones now use the IRQ domain APIs: - 88pm860x, tc3589x, db8500_prcmu Also some other interesting changes: - Intel's ICH LPC now supports Lynx Point - TI's twl4030-audio added a GPO child - tps6527 enabled its backlight subdevice - The twl6030 pwm driver moved to the new PWM subsystem And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x, palmas, ab8500, wm8994, wm5110, max8907 and the tps65xxx family."

When specified, a new resamplefd is provided that notifies the user when the irqchip has been resampled by the VM. This may, for instance, indicate an EOI. Also in this mode, posting of an interrupt through an irqfd only asserts the interrupt. On resampling, the interrupt is automatically de-asserted prior to user notification. This enables level triggered interrupts to be posted and re-enabled from vfio with no userspace intervention. All resampling irqfds can make use of a single irq source ID, so we reserve a new one for this interface.

Handling the crash from a separate thread is helpful because: - Ability to call invoke rproc_report_crash() from atomic context, due to the fact that many crashes trigger an interrupt, so this function can be called directly from ISR context. - Avoiding deadlocks which could happen if rproc_report_crash() is called from a function which indirectly holds the rproc lock. Handling the crash might involve: - Remoteproc register dump - Remoteproc stack dump - Remoteproc core dump - Saving Remoteproc traces so they can be read after the crash - Reseting the remoteproc in order to make it functional again (hard recovery) Right now, we only print the crash type which was detected, and only the mmufault type is supported. Remoteproc low-level drivers can add more types when needed.

This is due to the bugfix in -rc7: commit b98b60167279df3acac9422c3c9820d9ebbcf9fb Author: Wang Xingchao <xingchao.wang@intel.com> Date: Thu Sep 13 07:43:22 2012 +0800 drm/i915: HDMI - Clear Audio Enable bit for Hot Plug Since this code moved around a lot in -next git put that snippet at the wrong spot.

To avoid pushing out further -nightly branch to our QA where this is broken, do the backmerge and manually add the stuff git adds to -next from the patch in -fixes. Note that this doesn't show up in git's merge diff (and hence is also not handled by git rerere), which adds to the reasons why I'd like to fix this with a verbose backmerge. The git merge diff only shows a bunch of trivial conflicts of the "code changed in lines next to each another" kind. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

The new subdirs under the uapi/ directory are populated with Kbuild files that mostly do nothing at this time. Further patches will disintegrate the headers in each original directory and fill in the Kbuild files as they do it. These patches also: (1) fix up #inclusions of "foo.h" rather than <foo.h>. (2) Remove some redundant #includes from the DRM code. (3) Make the kernel build infrastructure handle Kbuild files both in the old places and the new UAPI place that both specify headers to be exported. (4) Fix some kernel tools that #include kernel headers during their build.

This commit adds rudimentary documentation about the required standard properties and describes the most commonly used interrupt specifiers.
