Subject: [PATCH 1/2] x86/kexec: Remove unnecessary arch_kexec_kernel_image_load()
Date: Thu, 15 Dec 2022 12:23:38 -0600	[thread overview]
Message-ID: <20221215182339.129803-2-helgaas@kernel.org> (raw)
In-Reply-To: <20221215182339.129803-1-helgaas@kernel.org>

From: Bjorn Helgaas <bhelgaas@google.com>

The x86 implementation of arch_kexec_kernel_image_load() is functionally
identical to the generic arch_kexec_kernel_image_load().

Remove it and use the generic arch_kexec_kernel_image_load().  No
functional change intended.
