[PATCH i-g-t v2 0/3] Introduce memory mapping tests

[Krzysztof Niemiec]

Hi,

This series introduces various tests related to memory mapping.

partial-remap (patch 1), mmap-boundaries (patch 2) and mmap-unmap (patch
3) tests were developed based on test cases made by Jann Horn.

partial-mmap and partial-unmap (both in patch 1) were developed to
replicate Mesa usage, as suggested by Lionel Landwerlin.

This series has been used to test these patches:

1ac5167b3a90 ("drm/i915/gem: Adjust vma offset for framebuffer mmap offset")
8bdd9ef7e9b1 ("drm/i915/gem: Fix Virtual Memory mapping boundaries calculation")

and

https://patchwork.freedesktop.org/series/136981/

Changelog:

v2:
 - Wrap uint64_t to pointer casts in from_user_pointer() so that the
   tests compile on 32-bit machines,
 - Fix duplicate handle assignment in mmap-unmap,
 - Prevent the tests from failing, if a map call fails - it might
   succeed on another offset type,
 - Swap mmap fail check and memory access in mmap-unmap to prevent a
   segfault,
 - Use gem_close() at the end of tests.

Thanks
Krzysztof
