Subject: uprobes: Do not setup ->active_uprobe/state prematurely
X-Git-Tag: v3.7-rc3~40^2~1^2~17
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=746a9e6ba24af2ccf03279c99d435a1b88ca5d17;p=pandora-kernel.git

uprobes: Do not setup ->active_uprobe/state prematurely

handle_swbp() sets utask->active_uprobe before handler_chain(),
and UTASK_SSTEP before pre_ssout(). This complicates the code
for no reason,  arch_ hooks or consumer->handler() should not
(and can't) use this info.

Change handle_swbp() to initialize them after pre_ssout(), and
remove the no longer needed cleanup-utask code.
