Subject: [PATCH v6 04/16] sparc: simplify module_alloc()
Date: Fri, 26 Apr 2024 11:28:42 +0300 [thread overview]
Message-ID: <20240426082854.7355-5-rppt@kernel.org> (raw)
In-Reply-To: <20240426082854.7355-1-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>
Suggested-by: Sam Ravnborg <sam@ravnborg.org>
Signed-off-by: Mike Rapoport (IBM) <rppt@kernel.org>
