[PATCH v6 04/16] sparc: simplify module_alloc()

[Mike Rapoport <rppt@kernel.org>]

From: "Mike Rapoport (IBM)" <rppt@kernel.org>

Define MODULES_VADDR and MODULES_END as VMALLOC_START and VMALLOC_END
for 32-bit and reduce module_alloc() to

	__vmalloc_node_range(size, 1, MODULES_VADDR, MODULES_END, ...)

as with the new defines the allocations becomes identical for both 32
and 64 bits.

While on it, drop unused include of <linux/jump_label.h>
