Subject: sh: kgdb: Fix up basic SMP support.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=14f087d839d9bd3f90ad69d4b3fde7d236c156b1;p=linux-beck.git

sh: kgdb: Fix up basic SMP support.

kgdb needs a kgdb_roundup_cpus() definition in the architecture backend,
so just copy over the MIPS version, which already does what we want.
