    selftests/mm: va_high_addr_switch: reduce test noise

    Patch series "Restructure va_high_addr_switch".

    The va_high_addr_switch memory selftest tests out some corner cases
    related to allocation and page/hugepage faulting around the switch
    boundary.  Currently, the page size and hugepage size have been statically
    defined.  Post FEAT_LPA2, the Aarch64 Linux kernel adds support for 4k and
    16k translation granules on higher addresses; we restructure the test to
    support the same.  In addition, we avoid invocation of the binary twice,
    in the shell script, to reduce test noise.

    This patch (of 2):

    When invoking the binary with "--run-hugetlb" flag, the testcases
    involving the base page are anyways going to be run.  Therefore, remove
    duplication by invoking the binary only once.
