Make thuge-gen skip instead of fail when it can't run due to system settings. If shmmax is too small or no 1G huge pages are available, the test now prints a warning and is marked as skipped.
Before Patch:
~ running ./thuge-gen ~ Bail out! Please do echo 262144 > /proc/sys/kernel/shmmax ~ Totals: pass:0 fail:0 xfail:0 xpass:0 skip:0 error:0 ~ [FAIL] not ok 28 thuge-gen ~ exit=1
After Patch:
~ running ./thuge-gen ~ ~ WARNING: shmmax is too small to run this test. ~ ~ Please run the following command to increase shmmax: ~ ~ echo 262144 > /proc/sys/kernel/shmmax ~ 1..0 ~ SKIP Test skipped due to insufficient shmmax value. ~ [SKIP] ok 29 thuge-gen ~ SKIP
