[igt-dev] [PATCH i-g-t] i915/gem_mmap_offset: Ignore ENOSPC error for making residency execbuf

[Zbigniew Kempczyński]

Platforms without ppgtt may be affected by ENOSPC when object is too big
to fit in gtt. Still we expect object will be cleared in pagefault path
so we can move forward even if execbuf is failing. To verify object
is cleared in both paths (execbuf/pagefault handler) we select them
randomly.
