2013-12-05cfg80211: fix WARN_ON for re-association to the expired BSSUjjal Roy
cfg80211 allows re-association in managed mode and if a user wants to re-associate to the same AP network after the time period of IEEE80211_SCAN_RESULT_EXPIRE, cfg80211 warns with the following message on receiving the connect result event. ------------[ cut here ]------------ WARNING: CPU: 0 PID: 13984 at net/wireless/sme.c:658 __cfg80211_connect_result+0x3a6/0x3e0 [cfg80211]() Call Trace: [<ffffffff81747a41>] dump_stack+0x46/0x58 [<ffffffff81045847>] warn_slowpath_common+0x87/0xb0 [<ffffffff81045885>] warn_slowpath_null+0x15/0x20 [<ffffffffa05345f6>] __cfg80211_connect_result+0x3a6/0x3e0 [cfg80211] [<ffffffff8107168b>] ? update_rq_clock+0x2b/0x50 [<ffffffff81078c01>] ? update_curr+0x1/0x160 [<ffffffffa05133d2>] cfg80211_process_wdev_events+0xb2/0x1c0 [cfg80211] [<ffffffff81079303>] ? pick_next_task_fair+0x63/0x170 [<ffffffffa0513518>] cfg80211_process_rdev_events+0x38/0x90 [cfg80211] [<ffffffffa050f03d>] cfg80211_event_work+0x1d/0x30 [cfg80211] [<ffffffff8105f21f>] process_one_work+0x17f/0x420 [<ffffffff8105f90a>] worker_thread+0x11a/0x370 [<ffffffff8105f7f0>] ? rescuer_thread+0x2f0/0x2f0 [<ffffffff8106638b>] kthread+0xbb/0xc0 [<ffffffff810662d0>] ? kthread_create_on_node+0x120/0x120 [<ffffffff817574bc>] ret_from_fork+0x7c/0xb0 [<ffffffff810662d0>] ? kthread_create_on_node+0x120/0x120 ---[ end trace 61f3bddc9c4981f7 ]--- The reason is that, in connect result event cfg80211 unholds the BSS to which the device is associated (and was held so far). So, for the event with status successful, when cfg80211 wants to get that BSS from the device's BSS list it gets a NULL BSS because the BSS has been expired and unheld already.

2013-12-05perf/x86: Fix constraint table end marker bugMaria Dimakopoulou
The EVENT_CONSTRAINT_END() macro defines the end marker as a constraint with a weight of zero. This was all fine until we blacklisted the corrupting memory events on Intel IvyBridge. These events are blacklisted by using a counter bitmask of zero. Thus, they also get a constraint weight of zero. The iteration macro: for_each_constraint tests the weight==0. Therefore, it was stopping at the first blacklisted event, i.e., 0xd0. The corrupting events were therefore considered as unconstrained and were scheduled on any of the generic counters. This patch fixes the end marker to have a weight of -1. With this, the blacklisted events get an empty constraint and cannot be scheduled which is what we want for now.

In checkin: 0c44c2d0f459 x86: Use asm goto to implement better modify_and_test() functions the various functions which do modify and test were unified and optimized using "asm goto". However, this change missed the detail that the bitops require an "Ir" constraint rather than an "er" constraint ("I" = integer constant from 0-31, "e" = signed 32-bit integer constant). This would cause code to miscompile if these functions were used on constant bit positions 32-255 and the build to fail if used on constant bit positions above 255.
