Subject: [PATCH v2 0/3] Fix va_high_addr_switch.sh test failure
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
Chunyu Hu (3):
selftests/mm: fix hugepages cleanup too early
selftests/mm: alloc hugepages in va_high_addr_switch test
selftests/mm: fix va_high_addr_switch.sh failure on x86_64
