"David S. Miller", Andreas Larsson, Linus Torvalds
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> Suggested-by: Sam Ravnborg <redacted> Signed-off-by: Mike Rapoport (IBM) <rppt@kernel.org> Reviewed-by: Sam Ravnborg <redacted> --- arch/sparc/include/asm/pgtable_32.h | 2 ++ arch/sparc/kernel/module.c | 25 +------------------------ 2 files changed, 3 insertions(+), 24 deletions(-)
