Hi Yinghai,

FYI, there are new compile warnings show up in

tree:   git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git master
head:   156b34aa66c1cb022b988c6ab75ef74d4da20331
commit: 692c07419d41fc6ccc9bd7c8798599ab6834427e [199/242] resource: Make find_resource could return just fit resource
config: i386-randconfig-m081 (attached as .config)

All error/warnings:

kernel/resource.c: In function 'find_resource':
kernel/resource.c:470:2: warning: large integer implicitly truncated to unsigned type [-Woverflow]

vim +470 kernel/resource.c
   460	/*
   461	 * Find empty slot in the resource tree given range and alignment.
   462	 */
   463	static int find_resource(struct resource *root, struct resource *new,
   464				resource_size_t size,
   465				struct resource_constraint  *constraint)
   466	{
   467		int ret = -1;
   468		LIST_HEAD(head);
   469		struct avail_resource *avail, *tmp;
 > 470		resource_size_t avail_start = 0, avail_size = -1ULL;
   471	
   472		if (!constraint->fit) {
   473			ret = __find_resource(root, NULL, new, size, constraint);
   474			if (!ret)
   475				new->end = new->start + size - 1;
   476			return ret;
   477		}
   478	
   479	again:
   480		/* find all suitable ones */
