tarfeef101 a4fb607edb there were a few cases of getppages getting called directly, which caused issues after vm_init is true, as that sets first and last to 0 in ram.c, which is used by stealmem. so those would fail after init. hence the issue. i simply changed those to use alloc_kpages, so now there should be no exceptions. ran one set of tests, but those pass now		%!s(int64=6) %!d(string=hai) anos
