[CRIU] [PATCH v4 1/4] make: move syscalls files and build to separated directory

Mon Nov 19 10:35:15 EST 2012


From: Stanislav Kinsbursky <skinsbursky at openvz.org>

This patch set moves all syscalls data to $(ARCH) directory ("x86_64" in this
particular case).
It does also some cleanup to generic Makefile.inc and syscalls-x86-64.sh.
