I've fumbled this, resulting in this this skipping everywhere.
Unfortunately no QA test report for this regression ...

The only thing the kernel can do is pin the buffers, which essentially
means no swapped tiled objects.

In order to exercise coherency across swapin/swapout of the same bo,
explicitly loop over all bo a couple of times.

Add a function to lock memory into RAM and use it in the
gem_tiled_swapping test to reduce the amount of allocated memory
required to force swapping. This also reduces the amount of time
required for the test to complete, since the data set is smaller.
The following durations were recorded with gem_tiled_swapping on a
haswell system before the change:
Subtest non-threaded: SUCCESS (55.889s)
Subtest threaded: SUCCESS (810.532s)
and after:
Subtest non-threaded: SUCCESS (11.804s)
Subtest threaded: SUCCESS (268.336s)
v2: add various assertions and requirements and make sure
gem_tiled_swapping works on systems with less RAM (Daniel Vetter)
v3: fix allocation size calculation

This has the upside that we'll never forget to add it to thrashing
tests. But we'll also never miss to move it when adding basic
functionality tests to existing binaries. Chris already started this
refining work in e.g.

More in line with the usual igt pattern and simplifies the code -
every called just wrapped it in igt_require.

The exercise is moving tiled objects in and out of swap. They are moved
en-block and we test them all, therefore we can randomly test different
bytes from each buffer to have reasonable coverage of all tiles. This
shifts the bulk of the work from checking the tiled bo to kswapd.

Use extra threads to cause extra memory pressure and stress upon the
relevant code. Limit the number of threads to available fences to avoid
falling off the fence cliff.

Reset the system to a vanilla state before we query how much RAM/swap
space is available for our testing.

If there is not enough free RAM+swap for us to execute our test, we will
hit OOM, so check first.

And shovel all the various helpers in there.
Also move igt_set_vt_graphics_mode to igt_kms.h since the function is
implemented in igt_kms.c. And it fits better. I kinda missed this in
the prep work.

With the header cleanup we can now give this header a suitable name,
since it now really only contains register access and other I/O
functions and assorted definitions.

With the new _f variants we can replace almost all of them.
Also remove a ton of checks for argc != 1, they're a bit useless ...

Mostly a sed job with too manual fixups:
- one case of using _exit instead of exit
- and one case which under some conditions use 77, so convert that
check to an igt_skip.

Let's start by a small set of tests, to eventually consider running
more.
The current list should then be:
gem_mmap
gem_pread_after_blit
gem_ring_sync_loop
gem_ctx_basic
gem_pipe_control_store_loop
gem_storedw_loop_render
gem_storedw_loop_blt
gem_storedw_loop_bsd
gem_render_linear_blits
gem_tiled_blits
gem_cpu_reloc
gem_exec_nop
gem_mmap_gtt
v2 add (Daniel Vetter)
gem_exec_bad_domains
gem_exec_faulting_reloc
gem_flink
gem_reg_read
gem_reloc_overflow
gem_tiling_max_stride
prime_*
