[PATCH v5 04/15] sparc: simplify module_alloc()

Mike Rapoport
2024-04-22T08:48:33Z

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 becames identical for both 32
and 64 bits.

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