The patch titled
Consolidate bust_spinlocks()
has been removed from the -mm tree. Its filename was
consolidate-bust_spinlocks.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Consolidate bust_spinlocks()
From: Kirill Korotaev <dev@sw.ru>
Part of long forgotten patch
http://groups.google.com/group/fa.linux.kernel/msg/e98e941ce1cf29f6?dmode=source
Since then, m32r grabbed two copies.
Leave s390 copy because of important absence of CONFIG_VT, but remove
references to non-existent timerlist_lock. ia64 also loses timerlist_lock.
