Message-Id: <20160712014201.11456-2-takahiro.akashi@linaro.org> Date: Tue, 12 Jul 2016 10:41:59 +0900 From: AKASHI Takahiro <takahiro.akashi@...aro.org> To: ebiederm@...ssion.com, vgoyal@...hat.com, dyoung@...hat.com, bhe@...hat.com, bauerman@...ux.vnet.ibm.com, arnd@...db.de Cc: kexec@...ts.infradead.org, linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linuxppc-dev@...ts.ozlabs.org, AKASHI Takahiro <takahiro.akashi@...aro.org> Subject: [RFC 1/3] syscall: add kexec_file_load to generic unistd.h 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.
