Subject: [PATCH 02/13 v2] Move EM_ARCOMPACT and EM_ARCV2 to
 uapi/linux/elf-em.h

These should never have been defined in the arch tree to begin with, and
now uapi/linux/audit.h header is going to use EM_ARCOMPACT and EM_ARCV2 in
order to define AUDIT_ARCH_ARCOMPACT and AUDIT_ARCH_ARCV2 which are needed
to implement syscall_get_arch() which in turn is required to extend the
generic ptrace API with PTRACE_GET_SYSCALL_INFO request.

Signed-off-by: Dmitry V. Levin <ldv@...linux.org>
---
v2: do not add EM_ARC, move EM_ARCOMPACT and EM_ARCV2 instead.
