Subject: [RFC 1/3] syscall: add kexec_file_load to generic unistd.h
Date: Tue, 12 Jul 2016 10:41:59 +0900	[thread overview]
Message-ID: <20160712014201.11456-2-takahiro.akashi@linaro.org> (raw)
In-Reply-To: <20160712014201.11456-1-takahiro.akashi@linaro.org>

Currently kexec_file_load is supported only on x86, but it will be
supported on powerpc and arm64 in near future. Since both archs
use asm-generic/unistd.h, this patch adds the entry to this file.
