Subject: [PATCH v19 02/13] arm64: Use ELF fields defined in 'struct kimage'
Date: Sun, 21 Feb 2021 09:49:19 -0800 [thread overview]
Message-ID: <20210221174930.27324-3-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_headers_mem
have been moved from 'struct kimage_arch' to 'struct kimage' as
elf_headers, elf_headers_sz, and elf_load_addr respectively.
Use the ELF fields defined in 'struct kimage'.
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>
