Subject: [PATCH v19 01/13] kexec: Move ELF fields to struct kimage
Date: Sun, 21 Feb 2021 09:49:18 -0800 [thread overview]
Message-ID: <20210221174930.27324-2-nramas@linux.microsoft.com> (raw)
In-Reply-To: <20210221174930.27324-1-nramas@linux.microsoft.com>
ELF related fields elf_headers, elf_headers_sz, and elf_load_addr are
defined in architecture specific 'struct kimage_arch' for x86, powerpc,
and arm64. The name of these fields are different in these
architectures that makes it hard to have a common code for setting up
the device tree for kexec system call.
Move the ELF fields to 'struct kimage' defined in include/linux/kexec.h
so common code can use it.
Signed-off-by: Lakshmi Ramasubramanian <nramas@linux.microsoft.com>
Suggested-by: Rob Herring <robh@kernel.org>
Fixes: 33488dc4d61f ("of: Add a common kexec FDT setup function")
Reported-by: kernel test robot <lkp@intel.com>
