From 3d01c1ce41fae0fb1d8e50589f9fb3b1fa376c1c Mon Sep 17 00:00:00 2001 From: Chen Gang Date: Thu, 24 Oct 2013 11:50:09 +0800 Subject: arc: kgdb: add default implementation for kgdb_roundup_cpus() arc supports kgdb, but need update -- add function kgdb_roundup_cpus(), or can not pass compiling. At present, add the simple generic one just like other architectures(e.g. tile, mips ...).
