2015-03-11ARM: vexpress: update CONFIG_USB_ISP1760 optionSudeep Holla
Commit 7ef077a8ad35 ("usb: isp1760: Move driver from drivers/usb/host/ to drivers/usb/isp1760/") moved the isp1760 driver and changed the Kconfig option. This makes CONFIG_USB_ISP1760_HCD not selectable directly anymore. This results in driver being not compiled in when using vexpress_defconfig and the USB is non-functional. This patch updates the CONFIG_USB_ISP1760_HCD to CONFIG_USB_ISP1760 to get back USB functional on vexpress platforms.

Otherwise the guest can abuse that control to cause e.g. PCIe Unsupported Request responses by disabling memory and/or I/O decoding and subsequently causing (CPU side) accesses to the respective address ranges, which (depending on system configuration) may be fatal to the host.

2015-03-10drm/i915: Prevent TLB error on first execution on SNBChris Wilson
Long ago I found that I was getting sporadic errors when booting SNB, with the symptom being that the first batch died with IPEHR != *ACTHD, typically caused by the TLB being invalid. These magically disappeared if I held the forcewake during the entire ring initialisation sequence. (It can probably be shortened to a short critical section, but the whole initialisation is full of register writes and so we would be taking and releasing forcewake almost continually, and so holding it over the entire sequence will probably be a net win!) Note some of the kernels I encounted the issue already had the deferred forcewake release, so it is still relevant. I know that there have been a few other reports with similar failure conditions on SNB, I think such as References: https://bugs.freedesktop.org/show_bug.cgi?id=80913 v2: Wrap i915_gem_init_hw() with its own security blanket as we take that path following resume and reset.

The kernel in_irq() function tests for hard-IRQ context only, so if a system is run with the kernel 'threadirqs' option selected, the test in intel_check_page_flip() generates lots of warnings, because then it gets called in soft-IRQ context. We can instead use in_interrupt() which allows for either type of interrupt, while still detecting and complaining about misuse of the page flip code if it is ever called from non-interrupt context.

2015-03-10drm: Fixup racy refcounting in plane_force_disableDaniel Vetter
Originally it was impossible to be dropping the last refcount in this function since there was always one around still from the idr. But in commit 83f45fc360c8e16a330474860ebda872d1384c8c Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Aug 6 09:10:18 2014 +0200 drm: Don't grab an fb reference for the idr we've switched to weak references, broke that assumption but forgot to fix it up. Since we still force-disable planes it's only possible to hit this when racing multiple rmfb with fbdev restoring or similar evil things. As long as userspace is nice it's impossible to hit the BUG_ON. But the BUG_ON would most likely be hit from fbdev code, which usually invovles the console_lock besides all modeset locks. So very likely we'd never get the bug reports if this was hit in the wild, hence better be safe than sorry and backport. Spotted by Matt Roper while reviewing other patches.

2015-03-10drm/mst: fix recursive sleep warning on qlockDaniel Vetter
With drm-next, we can get a backtrace from sleeping with mutex detection. this is due to the callback checking the txmsg state taking the mutex, which can cause a sleep inside a sleep, Daniel went over it and was happy we could drop this mutex in this case.

2015-03-10drm: Don't assign fbs for universal cursor support to filesChris Wilson
The internal framebuffers we create to remap legacy cursor ioctls to plane operations for the universal plane support shouldn't be linke to the file like normal userspace framebuffers. This bug goes back to the original universal cursor plane support introduced in commit 161d0dc1dccb17ff7a38f462c7c0d4ef8bcc5662 Author: Matt Roper <matthew.d.roper@intel.com> Date: Tue Jun 10 08:28:10 2014 -0700 drm: Support legacy cursor ioctls via universal planes when possible (v4) The isn't too disastrous since fbs are small, we only create one when the cursor bo gets changed and ultimately they'll be reaped when the window server restarts. Conceptually we'd want to just pass NULL for file_priv when creating it, but the driver needs the file to lookup the underlying buffer object for cursor id. Instead let's move the file_priv linking out of add_framebuffer_internal() into the addfb ioctl implementation, which is the only place it is needed. And also rename the function for a more accurate since it only creates the fb, but doesn't add it anywhere.
