[PATCH] __kmalloc: Generate BUG if size requested is too large.
I had an issue on ia64 where I got a bug in kernel/workqueue because kzalloc returned a NULL pointer due to the task structure getting too big for the slab allocator. Usually these cases are caught by the kmalloc macro in include/linux/slab.h. Compilation will fail if a too big value is passed to kmalloc. However, kzalloc uses __kmalloc which has no check for that. This patch makes __kmalloc bug if a too large entity is requested.
