Subject: [PATCH v3 1/2] x86/e820: Expose API to update e820 kexec and firmware tables externally.
Date: Fri, 26 Apr 2024 00:41:56 +0000	[thread overview]
Message-ID: <b726af213ad55053f8a7a1e793b01bb3f1ca9dd5.1714090302.git.ashish.kalra@amd.com> (raw)
In-Reply-To: <cover.1714090302.git.ashish.kalra@amd.com>

From: Ashish Kalra <ashish.kalra@amd.com>

Export a new API helper function e820__range_update_table() to update both
e820_table_kexec and e820_table_firmware. Move all current users of
e820__range_update_kexec() to use this new helper function.
