Subject[PATCH 1/2] x86/kexec: Remove unnecessary arch_kexec_kernel_image_load()
Date
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.
