[PATCH 0/4] selftest/vm fix segfault in mremap_test

[Sidhartha Kumar]

The mremap test currently segfaults because mremap
does not have a NOREPLACE flag which will fail if the
remap destination address collides with an existing mapping.
The segfault is caused by the mremap call destorying the
text region mapping of the program. This patch series fixes
the segfault by sanitizing the mremap destination address
and introduces other minor fixes to the test case. 

Sidhartha Kumar (4):
  selftest/vm: verify mmap addr in mremap_test
  selftest/vm: verify remap destination address in mremap_test
  selftest/vm: support xfail in mremap_test
  selftest/vm: add skip support to mremap_test
