Btw, this snippet

static int unmap_old_vmas(void *premmapped_addr, unsigned long premmapped_len,
		      void *bootstrap_start, unsigned long bootstrap_len)
{
	void *p[6] = {NULL, 0, 0, 0, 0, (void *) TASK_SIZE};
...
	for (i = 0; i < 6; i += 2) {
should be < 5 i think
		ret = sys_munmap(p[i], p[i + 1] - p[i]);
}
