drm/tegra: Fixes for v3.14-rc3

These patches contain a fix for a potential hang when the RGB output is
disabled twice, a typofix that prevents the framebuffer console from
being restored on ->lastclose() and an optimization to do as little work
as possible during host1x job submission.

CIK parts are 128x128, older parts are 64x64.
Signed-off-by: NAlex Deucher <alexander.deucher@amd.com>

Some hardware may not support standard 64x64 cursors.  Add
a drm cap to query the cursor size from the kernel.  Some examples
include radeon CIK parts (128x128 cursors) and armada (32x64 or 64x32).
This allows things like device specific ddxes to remove asics specific
logic and also allows xf86-video-modesetting to work properly with hw
cursors on this hardware. Default to 64 if the driver doesn't specify
a size.

Commit a5540906 ("drm/nv50-: map TTM_PL_SYSTEM through a BAR for CPU

mem->mm_node is not a nouveau_mem for AGP-using pre-NV50 cards, but a
drm_mm_node, as created by the ttm_bo_manager_func. As such, extend the
untiled check to explicitly include all pre-nv50 cards.

  The changelog should have plenty of details but basically, without
  this fix, we get random user segfaults and/or corruptions due to
  missing TLB/hash flushes.  Aneesh series of 3 patches fixes it.

  We have some vDSO vs.  perf fixes from Anton, some small EEH fixes
  from Gavin, a ppc32 regression vs the stack overflow detector, and a
  fix for the way we handle PCIe host bridge speed settings on pseries
  (which is needed for proper operations of AMD graphics cards on
  Power8)"

  powerpc/eeh: Disable EEH on reboot
  powerpc/eeh: Cleanup on eeh_subsystem_enabled
  powerpc/powernv: Rework EEH reset

  powerpc: Set the correct ksp_limit on ppc32 when switching to irq stack

This is not a buffer overflow in the traditional sense: we don't
overflow any *kernel* buffers, but we do mis-count the amount of data we
copy back to user space for the SYSLOG_ACTION_READ_ALL case.

In particular, if the user buffer is too small to hold everything, and
*if* there is a continuation line at just the right place, we can end up
giving the user more data than he asked for.

The reason is that we first count up the number of bytes all the log
records contains, then we walk the records again until we've skipped the
records at the beginning that won't fit, and then we walk the rest of
the records and copy them to the user space buffer.

And in between that "skip the initial records that won't fit" and the
"copy the records that *will* fit to user space", we reset the 'prev'
variable that contained the record information for the last record not
copied.  That meant that when we started copying to user space, we now
had a different character count than what we had originally calculated
in the first record walk-through.

The fix is to simply not clear the 'prev' flags value (in both cases
where we had the same logic: syslog_print_all and kmsg_dump_get_buffer:
the latter is used for pstore-like dumping)

When doing reset in order to recover the affected PE, we issue
hot reset on PE primary bus if it's not root bus. Otherwise, we
issue hot or fundamental reset on root port or PHB accordingly.
For the later case, we didn't cover the situation where PE only
includes root port and it potentially causes kernel crash upon
EEH error to the PE.

The patch reworks the logic of EEH reset to improve the code
readability and also avoid the kernel crash.
