[PATCH 1/2] devres: support sizes greater than an unsigned long

From: Cristian Stoica
Date: Tue Oct 07 2014 - 11:40:50 EST


As in 4f452e8aa492c0b8028ca9b4bdb4d018ba28c6c7, use resource_size_t
to accomodate sizes greater than the size of an unsigned long int on
platforms that have more than 32 bit physical addresses.
