[IA64] Wire up kcmp syscall

emaschino · aegl · commit d305c4773458 · 2015-10-28T14:22:59.000-07:00
systemd > 218 fails to compile on ia64 with: error: ‘__NR_kcmp’ undeclared [1]. I've been told that this is because the kcmp syscall hasn't been wired up for the ia64 arch [2]. The proposed patch thus wire up the kcmp syscall for the ia64 arch.
