In commit efb78fa86e95 ("lib/test_meminit: allocate pages up to order MAX_ORDER"), the loop for testing pages is set to "<= MAX_ORDER" which causes crashes in systems when run. Fix this to "< MAX_ORDER" to fix the test to work properly.
What are the crashes you are seeing? Are those OOMs?
They are WARN_ON() triggers. They are burried in the Android build system, let me see if I can uncover them.
IIUC it should be valid to allocate with MAX_ORDER.
"should", but I no longer get runtime warnings with this patch applied, so something is wrong :)
Let me go dig for the logs again...
