The three patches fix the va_high_addr_switch.sh test failure on x86_64.
Patch 1 fixes the hugepage setup issue that nr_hugepages is reset too early in run_vmtests.sh and break the later va_high_addr_switch testing.
Patch 2 adds hugepage setup in va_high_addr_switch test, so that it can still work if vm_runtests.sh changes the hugepage setup someday.
Patch 3 fixes the test failure caused by the hint addr align method change in hugetlb_get_unmapped_area().
Changes in v2: - patch 1 renames nr_hugepgs_origin to orig_nr_hugepgs - add a patch 2 to setup hugeapges in va_high_addr_switch test
