Intel fixes for regressions, black screens and hangs, for 3.15.

* tag 'drm-intel-fixes-2014-05-16' of git://anongit.freedesktop.org/drm-intel:
  drm/i915: Increase WM memory latency values on SNB
  drm/i915: restore backlight precision when converting from ACPI
  drm/i915: Use the first mode if there is no preferred mode in the EDID
  drm/i915/dp: force eDP lane count to max available lanes on BDW
  drm/i915/vlv: reset VLV media force wake request register
  drm/i915/SDVO: For sysfs link put directory and target in correct order
  drm/i915: use lane count and link rate from VBT as minimums for eDP
  drm/i915: clean up VBT eDP link param decoding
  drm/i915: consider the source max DP lane count too

On SNB the BIOS provided WM memory latency values seem insufficient to
handle high resolution displays.

In this particular case the display mode was a 2560x1440@60Hz, which
makes the pixel clock 241.5 MHz. It was empirically found that a memory
latency value if 1.2 usec is enough to avoid underruns, whereas the BIOS
provided value of 0.7 usec was clearly too low. Incidentally 1.2 usec
is what the typical BIOS provided values are on IVB systems.

Increase the WM memory latency values to at least 1.2 usec on SNB.
Hopefully this won't have a significant effect on power consumption.

v2: Increase the latency values regardless of the pixel clock

When we set backlight on behalf of ACPI opregion, we will convert the
backlight value in the 0-255 range defined in opregion to the actual
hardware level. Commit 22505b82 (drm/i915: avoid brightness overflow
when doing scale) is meant to fix the overflow problem when doing the
conversion, but it also caused a problem that the converted hardware
level doesn't quite represent the intended value: say user wants maximum
backlight level(255 in opregion's range), then we will calculate the
actual hardware level to be: level = freq / max * level, where freq is
the hardware's max backlight level(937 on an user's box), and max and
level are all 255. The converted value should be 937 but the above
calculation will yield 765.

To fix this issue, just use 64 bits to do the calculation to keep the
precision and avoid overflow at the same time.

This matches the algorithm used by earlier kernels when selecting the
mode for the fbcon. And only if there is no modes at all, do we fall
back to using the BIOS configuration. Seamless transition is still
preserved (from the BIOS configuration to ours) so long as the BIOS has
also chosen what we hope is the native configuration.

There are certain BDW high res eDP machines that regressed due to

commit 38aecea0
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Mon Mar 3 11:18:10 2014 +0100

    drm/i915: reverse dp link param selection, prefer fast over wide again

The commit lead to 2 lanes at 5.4 Gbps being used instead of 4 lanes at
2.7 Gbps on the affected machines. Link training succeeded for both, but
the screen remained blank with the former config. Further investigation
showed that 4 lanes at 5.4 Gbps worked also.

The root cause for the blank screen using 2 lanes remains unknown, but
apparently the driver for a certain other operating system by default
uses the max available lanes. Follow suit on Broadwell eDP, for at least
until we figure out what is going on.

  mm, thp: close race between mremap() and split_huge_page()
  mm: postpone the disabling of kmemleak early logging
  MAINTAINERS: update maintainership of LTP
  drivers/rtc/rtc-hym8563.c: set uie_unsupported

It's critical for split_huge_page() (and migration) to catch and freeze
all PMDs on rmap walk.  It gets tricky if there's concurrent fork() or
mremap() since usually we copy/move page table entries on dup_mm() or
move_page_tables() without rmap lock taken.  To get it work we rely on
rmap walk order to not miss any entry.  We expect to see destination VMA
after source one to work correctly.

But after switching rmap implementation to interval tree it's not always
possible to preserve expected walk order.

It works fine for dup_mm() since new VMA has the same vma_start_pgoff()
/ vma_last_pgoff() and explicitly insert dst VMA after src one with
vma_interval_tree_insert_after().

But on move_vma() destination VMA can be merged into adjacent one and as
result shifted left in interval tree.  Fortunately, we can detect the
situation and prevent race with rmap walk by moving page table entries
under rmap lock.  See commit 38a76013.

Problem is that we miss the lock when we move transhuge PMD.  Most
likely this bug caused the crash[1].

before the full kmemleak tracing is actually enabled.  In this small
window, kmem_cache_create() is called by kmemleak which triggers
additional memory allocation that are not traced.  This patch restores
the original logic with kmemleak_early_log disabling when kmemleak is
fully functional.

With tk->wall_to_monotonic.tv_nsec being a 32-bit value on 32-bit
systems, (tk->wall_to_monotonic.tv_nsec << tk->shift) in update_vsyscall()
may lose upper bits or, worse, add them since compiler will do this:

commit bce7560d (locks: consolidate checks for compatible

F_GETLK handler.

flock64_to_posix_lock is a shared codepath between F_GETLK and F_SETLK,
but the f_mode checks should only be applicable to the F_SETLK codepaths
according to POSIX.

Instead of just reverting the patch, add a new function to do this
checking and have the F_SETLK handlers call it.
