Subject: kdb: kdb_current_task shouldn't be exported
The kdb_current_task variable has been declared in
"kernel/debug/kdb/kdb_private.h" since 2010 when kdb was added to the
mainline kernel. This is not a public header. There should be no reason
that kdb_current_task should be exported and there are no in-kernel users
that need it. Remove the export.
