Subject: [RFC PATCH 2/3] x86/boot/e820: Make e820_type_to_string() external
Date: Sat, 11 Jun 2022 21:48:58 +0100 [thread overview]
Message-ID: <20220611204859.234975-2-atomlin@redhat.com> (raw)
In-Reply-To: <20220611204859.234975-1-atomlin@redhat.com>
No functional change.
This patch allows e820_type_to_string() to be available for
external use, in preparation to enhance the error message
generated by arch_rmrr_sanity_check().
