[Mesa-stable] [PATCH 00/16] anv: Fix our 48-bit problems

[Jason Ekstrand]

This patch series aims to fix the remaining 48-bit problems in the Vulkan
driver.  As such, the entire thing will be CC'd to stable before landing.

The first 5 patches fix the driver to handle memory aliasing correctly.
Vulkan allows you to bind multiple buffers or images to overlapping memory
regions so long as you get your layout transitions correct.  Up until now,
we've been doing a memset at vkBindImageMemory time to initialize auxiliary
surfaces which isn't valid in light of aliasing.  Instead, these patches
provide actual support for layout transitions from UNDEFINED to other
layouts.  This isn't actually a 48-bit issue but the other patches cause a
change in the behavior of some CTS tests which makes them start failing due
to memory aliasing problems.

The next 10 patches refactor memory type setup and make us advertise 2
heaps on platforms with a lot of memory.  For justification, see the
comment in patch 15.

The last patch just extends the new pass added in patch 2 for gen7-8.  It's
fairly straightforward but completely untested.  Hopefully it will help
Nanley or someone else if they ever need it.
