- vm_phys_alloc_freelist_pages() can be called by vm_page_alloc_freelist() to allocate a page from a specific freelist. In the NUMA case it did not properly map the public VM_FREELIST_* constants to the correct backing freelists, nor did it try all NUMA domains for allocations from VM_FREELIST_DEFAULT. - vm_phys_alloc_pages() did not pin the thread and each call to vm_phys_alloc_freelist_pages() fetched the current domain to choose which freelist to use. If a thread migrated domains during the loop in vm_phys_alloc_pages() it could skip one of the freelists. If the other freelists were out of memory then it is possible that vm_phys_alloc_pages() would fail to allocate a page even though pages were available resulting in a panic in vm_page_alloc().
