maya | Add what appears to be the fixes to CVE-2019-0154, CVE-2019-0155.
This commit requires review, but I'd also like it to be tested by others
while it is being reviewed.
CVE-2019-0155:
It was discovered that the Intel i915 graphics chipsets allowed userspace
to modify page table entries via writes to MMIO from the Blitter Command
Streamer and expose kernel memory information. A local attacker could use
this to expose sensitive information or possibly elevate privileges.
CVE-2019-0154:
It was discovered that the Intel i915 graphics chipsets could cause
a system hang when userspace performed a read from GT memory mapped
input output (MMIO) when the product is in certain low power states.
A local attacker could use this to cause a denial of service.

mrg | add support for kabylake and skylake GT4 (untested) GPUs.
largely taken from openbsd and linux 4.13 trees (which
have this code identical), with mimimal porting to netbsd.
i have not installed (and thus tested) the newer referenced
firmware files.
only real local change is to fix IS_BROXTON() macro to check
the things valid in this era of drm. previous match would
attach on KBL, and then a loop would never exit.
tested on kabylake P630. needs mesa 11.x or newer for GL
to work.
ok @riastradh.

kamil | Remove UB from definition of symbols in i915_reg.h
Kernel Undefined Behavior Sanitizer enforces more warnings in build time.
This makes the build fatal in the drm/i915 code in:
- intel_ddi_put_crtc_pll(),
- intel_ddi_clock_get(),
- intel_ddi_pll_enable(),
- intel_ddi_setup_hw_pll_state().
The error message in all the cases says:
error: case label does not reduce to an integer constant
Set the type of the value left shifted to unsigned.
This change is required to build NetBSD/amd64 with KUBSan.

drm/i915: Avoid div-by-zero when pixel_multiplier is zero
On certain platforms pixel_multiplier is read out in
.get_pipe_config(), but it also gets used to calculate the
pixel clock in intel_sdvo_get_config(). If the pipe is disabled
but some SDVO outputs are active, we may end up dividing by zero
in intel_sdvo_get_config().
Fixes https://bugs.freedesktop.org/show_bug.cgi?id=3D76520
Tweak slightly sketchy logic in linux_idr.
1. idr_preload can fail if you don't set __GFP_WAIT.
2. If idr_preload fails, it is wrong for idr_alloc to assert.
3. There is no way for idr_alloc to know what flags idr_preload got.
Probably won't *fix* any bugs, but if there is a bug with a missing
__GFP_WAIT, then we will learn about a trifle sooner.
Fix error branch in ttm_dma_tt_init to avoid double-free.
Should fix symptom of PR kern/52438, but who knows what underlying
problem causes us to reach the error branch in the first place.
Fix lockdebug_locked annotations.
When thread A grants ownership to thread B waiting with a context,
thread B needs to assert lockdebug_locked; otherwise, when it
releases, lockdebug_unlocked thinks it's releasing an unlocked
ww_mutex.
Fixes LOCKDEBUG failure with radeon noticed by martin@.

Add what appears to be the fixes to CVE-2019-0154, CVE-2019-0155.
This commit requires review, but I'd also like it to be tested by others
while it is being reviewed.
CVE-2019-0155:
It was discovered that the Intel i915 graphics chipsets allowed userspace
to modify page table entries via writes to MMIO from the Blitter Command
Streamer and expose kernel memory information. A local attacker could use
this to expose sensitive information or possibly elevate privileges.
CVE-2019-0154:
It was discovered that the Intel i915 graphics chipsets could cause
a system hang when userspace performed a read from GT memory mapped
input output (MMIO) when the product is in certain low power states.
A local attacker could use this to cause a denial of service.
