Since this is a testing-only feature it should ever hurt, but I figured it'll help with regression-testing -fixes. So I left it in and didn't postpone it to 3.14. - Display power well refactoring from Imre. Would have caused major pain conflict with the bdw stage 1 patches if I'd postpone this to -next. It's only an relatively small interface rework, so shouldn't cause pain. It's also been in my tree since almost 3 weeks already. That accounts for about two thirds of the pull, otherwise just bugfixes: - vlv backlight fix from Jesse/Jani - vlv vblank timestamp fix from Jesse - improved edp detection through vbt from Ville (fixes a vlv issue) - eDP vdd fix from Paulo - fixes for dvo lvds on i830M - a few smaller things all over Note: This contains a backmerge of v3.12. Since the -internal branch always applied on top of -nightly I need that unified base to merge bdw patches. So you'll get a conflict with radeon connector props when pulling this (and nouveau/master will also conflict a bit when Ben doesn't rebase). The backmerge itself only had conflicts in drm/i915. There's also a tiny conflict between Jani's backlight fix and your sysfs lifetime fix in drm-next. * tag 'drm-intel-fixes-2013-11-07' of git://people.freedesktop.org/~danvet/drm-intel: (940 commits) drm/i915/vlv: use per-pipe backlight controls v2 drm/i915: make backlight functions take a connector drm/i915: move opregion asle request handling to a work queue drm/i915/vlv: use PIPE_START_VBLANK interrupts on VLV drm/i915: Make intel_dp_is_edp() less specific drm/i915: Give names to the VBT child device type bits drm/i915/vlv: enable HDA display audio for Valleyview2 drm/i915/dvo: call ->mode_set callback only when the port is running drm/i915: avoid unclaimed registers when capturing the error state drm/i915: Enable DP port CRC for the "auto" source on g4x/vlv drm/i915: scramble reset support for DP port CRC on vlv drm/i915: scramble reset support for DP port CRC on g4x drm/i916: add "auto" pipe CRC source ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the bits in the VBT child device type have some speciifc meaning, so looking for an exact match isn't always the right thing.

But since the internal branch was based upon our drm-intel-nightly integration branch I need to resolve all the oustanding conflicts in drm/i915 with a backmerge to make the 60+ patches apply properly.

ARC vmalloc fault handler however was using mm. A vmalloc fault for non user task context (actually pre-userland, from init thread's open for /dev/console) caused the handler to deref NULL mm (for mm->pgd) The reasons it worked so far is amazing: 1. By default (!SMP), vmalloc fault handler uses a cached value of PGD. In SMP that MMU register is repurposed hence need for mm pointer deref. 2. In pre-3.12 SMP kernel, the problem triggering vmalloc didn't exist in pre-userland code path - it was introduced with commit 20bafb3d23d108bc "n_tty: Move buffers into n_tty_data" Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Gilad Ben-Yossef <gilad@benyossef.com> Cc: Noam Camus <noamc@ezchip.com> Cc: stable@vger.kernel.org #3.10 and 3.11 Cc: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

What triggered it is that my WSM-EP is broken :-( [ 0.001000] tsc: Fast TSC calibration using PIT [ 0.002000] tsc: Detected 2533.715 MHz processor [ 0.500180] TSC synchronization [CPU#0 -> CPU#6]: [ 0.505197] Measured 3 cycles TSC warp between CPUs, turning off TSC clock. [ 0.004000] tsc: Marking TSC unstable due to check_tsc_sync_source failed For some reason it consistently detects TSC skew, even though NHM+ should have a single clock domain for 'reasonable' systems. This marks sched_clock_stable=0, which means that we do fancy stuff to try and get a 'sane' clock. Part of this fancy stuff relies on the tick, clearly that's gone when NOHZ=y. So for idle cpus time gets stuck, until it either wakes up or gets kicked by another cpu. While this is perfectly fine for the scheduler -- it only cares about actually running stuff, and when we're running stuff we're obviously not idle. This does somewhat break down for perf which can trigger events just fine on an otherwise idle cpu. So I've got NMIs get get 'measured' as taking ~1ms, which actually don't last nearly that long: <idle>-0 [013] d.h. 886.311970: rcu_nmi_enter <-do_nmi ... <idle>-0 [013] d.h. 886.311997: perf_sample_event_took: HERE!!! : 1040990 So ftrace (which uses sched_clock(), not the fancy bits) only sees ~27us, but we measure ~1ms !! Now since all this measurement stuff lives in x86 code, we can actually fix it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The order of arguments in the call to vco_set() for the ICST clocks appears to have been switched in error, which results in the VCO not being initialised correctly. This in turn stops the integrated LCD on things like Integrator/CP from working correctly. This patch fixes the order and restores the expected functionality.

Because of this, the SD driver was getting the incorrect clock value. This prevented the SD driver from initializing correctly.

This bug has been introduced by commit 6b72333d ("clk: mvebu: add Armada 370 SoC-centric clock init"). A wrong tclk frequency affects the following drivers: mvsdio, mvneta, i2c-mv64xxx and mvebu-devbus. This list may be incomplete. About the mvneta Ethernet driver, note that the tclk frequency is used to compute the Rx time coalescence. Then, this bug harms the coalescence configuration and also degrades the networking performances with the default values.

| | | * | | | | clk: nomadik: set all timers to use 2.4 MHz TIMCLKLinus Walleij2013-10-011-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a regression for the Nomadik on the main system timers. The Nomadik seemed a bit slow and its heartbeat wasn't looking healthy. And it was not strange, because it has been connected to the 32768 Hz clock at boot, while being told by the clock driver that it was 2.4MHz. Actually connect the TIMCLK to 2.4MHz by default as this is what we want for nice scheduling, clocksource and clock event.
