The hugetlb vma mremap() test currently maps 1GB of memory to trigger pmd sharing and make sure that 'unshare' path in mremap code works. The test originally only mapped 10MB of memory (as specified by the header comment) but was later modified to 1GB to tackle this case. However, not all machines will have 1GB of memory to spare for this test. Adding a mapping size arg will allow run_vmtest.sh to pass an adequate mapping size, while allowing users to run the test independently with arbitrary size mappings.
