Add a test to verify that pwriting to a future scanout buffer works
correctly. The specific problem occurs when the buffer is already
UC/WT before the pwrite, not the current scanout buffer, and not
currently in the CPU write domain. With the buggy kernel no clflush
will be performed after the pwrite, and hence we end up with cache
dirt on the display.
The problem only affects LLC platforms (non-LLC would clflush anyway
after pwrite), but we can let the test run on all platforms.

The command parser's batch_len optimization causes the parser to
reject this batch as not having an MI_BATCH_BUFFER_END because
the length was not set correctly.

The size of the batch buffer passed to the kernel is significantly
larger than the size of the batch buffer passed to the function. A
proposed optimization as part of the batch copy kernel series is to
use batch_len for the copy and parse operations, which leads to a
false "batch without MI_BATCH_BUFFER_END" failure for this test.
To fix this, modify the test to set batch_start_offset and batch_len
such that they define the range of actual commands in the batch,
including a few of the surrounding nops for alignment purposes.
v2: update batch_start_offset as well

This test has a few checks that batch buffer addresses in the error
state match the expected address for the userspace supplied batch.
But the batch buffer copy piece of the command parser means that
the logged addresses are actually _supposed_ to be different. So

igt/gem_tiled_wb: Exercise CPU mmaps with swizzling
brought along a few interlopers.
This exercises the the extended get_tiling ioctl in order to determine
proper swizzling for direct access to objects through WB.
Userspace cannot handle bit17 swizzling through wc mmaps (because bit17
requires swizzling based on the actual physical address of the page -
which is unknown to userspace) and so we need an extended get_tiling
ioctl to report the actual as well as the logical swizzling on an
object.

We were having a problem where the system-suspend test was passing,
but then the next test - gem-execbuf-stress - was failing because of
bugs caused by the suspend subtest. So add a single test that emulates
the same problem, and another test that just sets a mode after resume.
This way, we should be reproducing the problem even if you don't run
the tests in the order they are defined.

Make sure DSPSURF will change during the panning operation
in flip-vs-panning-vs-hang.
This will now test agains bugs between the kernel's mmio vs.
CS flip race handling and GPU resets. If the kernel is buggy
if will fail to notice that the panning operation changed the
base address before the GPU reset had a chance to deal with the
pending page flips, and so the flip would never complete due to
DSPSURFLIVE not matching the expected value.
