Patch series "Fix va_high_addr_switch.sh test failure - again", v1.
There are two issues exist for the va_high_addr_switch test. One issue is
the test return value is ignored in va_high_addr_switch.sh. The second is
the va_high_addr_switch requires 6 hugepages but it requires 5.
Besides that, the nr_hugepages setup in run_vmtests.sh for arm64 can be
done in va_high_addr_switch.sh too.
This patch: (of 3)
The return value should be return value of va_high_addr_switch, otherwise
a test failure would be silently ignored.
Fixes: d9d957bd7b61 ("selftests/mm: alloc hugepages in va_high_addr_switch
test")
