slab: make create_kmalloc_cache() work with 32-bit sizes
KMALLOC_MAX_CACHE_SIZE is 32-bit so is the largest kmalloc cache size.
Christoph said:
:
: Ok SLABs maximum allocation size is limited to 32M (see
: include/linux/slab.h:
:
: #define KMALLOC_SHIFT_HIGH ((MAX_ORDER + PAGE_SHIFT - 1) <= 25 ? \
: (MAX_ORDER + PAGE_SHIFT - 1) : 25)
:
: And SLUB/SLOB pass all larger requests to the page allocator anyways.
