Subject: [PATCH 3/3] arch/x86: Do not include <asm/bootparam.h> in several header files
Date: Wed, 6 Dec 2023 13:38:39 +0100 [thread overview]
Message-ID: <20231206125433.18420-4-tzimmermann@suse.de> (raw)
In-Reply-To: <20231206125433.18420-1-tzimmermann@suse.de>
Remove the include statement for <asm/bootparam.h> from several header
files that don't require it. Limits the exposure of the boot parameters
within the Linux kernel code.
Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de>
