+Subject: [PATCH] src/privsep-linux.c: add support for arc (#28)
+
+Fix the following build failure:
+
+privsep-linux.c:206:4: error: #error "Platform does not support seccomp filter yet"
+ # error "Platform does not support seccomp filter yet"
+ ^~~~~
+In file included from privsep-linux.c:36:
+privsep-linux.c:213:38: error: 'SECCOMP_AUDIT_ARCH' undeclared here (not in a function); did you mean 'SECCOMP_ALLOW_ARG'?
+ BPF_JUMP(BPF_JMP + BPF_JEQ + BPF_K, SECCOMP_AUDIT_ARCH, 1, 0),
+ ^~~~~~~~~~~~~~~~~~
+
+It should be noted that AUDIT_ARCH_{ARCOMPACT,ARCV2} is only defined
+since kernel 5.2 and
+https://github.com/torvalds/linux/commit/67f2a8a29311841ba6ab9b0e2d1b8f1e9978cd84
+
+Detection of arc compact and arc v2 have been "copy/pasted" from
+https://github.com/wbx-github/uclibc-ng/commit/afab56958f1cbb47b831ee3ebff231dfbae74af2
+
+Fixes:
