Subject: [PATCH v5 04/15] sparc: simplify module_alloc()
Date: Mon, 22 Apr 2024 12:44:25 +0300	[thread overview]
Message-ID: <20240422094436.3625171-5-rppt@kernel.org> (raw)
In-Reply-To: <20240422094436.3625171-1-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 becames identical for both 32
and 64 bits.

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

Suggested-by: Sam Ravnborg <sam@ravnborg.org>
