Using "%lu" to print size_t variables causes build warnings on i386 and
probably other architectures:
kernel/dma/swiotlb.c:210:35: warning: format '%lu' expects argument of type
'long unsigned int', but argument 3 has type 'size_t' {aka 'unsigned int'}
[-Wformat=]
panic("%s: Failed to allocate %lu bytes align=0x%lx\n",
~~^
%u
__func__, alloc_size, PAGE_SIZE);
~~~~~~~~~~
Replace "%lu" with "%zu".

Andrew, can you please fold this into "treewide: add checks for the return
value of memblock_alloc*()"?
