PM: runtime: Resume the device earlier in __device_release_driver()

2020-11-10T09:29:07+00:00

commit 9226c504e364158a17a68ff1fe9d67d266922f50 upstream. Since the device is resumed from runtime-suspend in __device_release_driver() anyway, it is better to do that before looking for busy managed device links from it to consumers, because if there are any, device_links_unbind_consumers() will be called and it will cause the consumer devices' drivers to unbind, so the consumer devices will be runtime-resumed. In turn, resuming each consumer device will cause the supplier to be resumed and when the runtime PM references from the given consumer to it are dropped, it may be suspended. Then, the runtime-resume of the next consumer will cause the supplier to resume again and so on. Update the code accordingly. Signed-off-by: Rafael J.

Revert "ARC: entry: fix potential EFA clobber when TIF_SYSCALL_TRACE"

2020-11-10T09:29:07+00:00

This reverts commit 00fdec98d9881bf5173af09aebd353ab3b9ac729. (but only from 5.2 and prior kernels) The original commit was a preventive fix based on code-review and was auto-picked for stable back-port (for better or worse). It was OK for v5.3+ kernels, but turned up needing an implicit change 68e5c6f073bcf70 "(ARC: entry: EV_Trap expects r10 (vs. r9) to have exception cause)" merged in v5.3 which itself was not backported. So to summarize the stable backport of this patch for v5.2 and prior kernels is busted and it won't boot. The obvious solution is backport 68e5c6f073bcf70 but that is a pain as it doesn't revert cleanly and each of affected kernels (so far v4.19, v4.14, v4.9, v4.4) needs a slightly different massaged varaint. So the easier fix is to simply revert the backport from 5.2 and prior. The issue was not a big deal as it would cause strace to sporadically not work correctly. Waldemar Brodkorb first reported this when running ARC uClibc regressions on latest stable kernels (with offending backport). Once he bisected it, the analysis was trivial, so thx to him for this.

ARC: stack unwinding: avoid indefinite looping

2020-11-10T09:29:07+00:00

commit 328d2168ca524d501fc4b133d6be076142bd305c upstream. Currently stack unwinder is a while(1) loop which relies on the dwarf unwinder to signal termination, which in turn relies on dwarf info to do so. This in theory could cause an infinite loop if the dwarf info was somehow messed up or the register contents were etc. This fix thus detects the excessive looping and breaks the loop. | Mem: 26184K used, 1009136K free, 0K shrd, 0K buff, 14416K cached | CPU: 0.0% usr 72.8% sys 0.0% nic 27.1% idle 0.0% io 0.0% irq 0.0% sirq | Load average: 4.33 2.60 1.11 2/74 139 | PID PPID USER STAT VSZ %VSZ CPU %CPU COMMAND | 133 2 root SWN 0 0.0 3 22.9 [rcu_torture_rea] | 132 2 root SWN 0 0.0 0 22.0 [rcu_torture_rea] | 131 2 root SWN 0 0.0 3 21.5 [rcu_torture_rea] | 126 2 root RW 0 0.0 2 5.4 [rcu_torture_wri] | 129 2 root SWN 0 0.0 0 0.2 [rcu_torture_fak] | 137 2 root SW 0 0.0 0 0.2 [rcu_torture_cbf] | 127 2 root SWN 0 0.0 0 0.1 [rcu_torture_fak] | 138 115 root R 1464 0.1 2 0.1 top | 130 2 root SWN 0 0.0 0 0.1 [rcu_torture_fak] | 128 2 root SWN 0 0.0 0 0.1 [rcu_torture_fak] | 115 1 root S 1472 0.1 1 0.0 -/bin/sh | 104 1 root S 1464 0.1 0 0.0 inetd | 1 0 root S 1456 0.1 2 0.0 init | 78 1 root S 1456 0.1 0 0.0 syslogd -O /var/log/messages | 134 2 root SW 0 0.0 2 0.0 [rcu_torture_sta] | 10 2 root IW 0 0.0 1 0.0 [rcu_preempt] | 88 2 root IW 0 0.0 1 0.0 [kworker/1:1-eve] | 66 2 root IW 0 0.0 2 0.0 [kworker/2:2-eve] | 39 2 root IW 0 0.0 2 0.0 [kworker/2:1-eve] | unwinder looping too long, aborting !

USB: Add NO_LPM quirk for Kingston flash drive

2020-11-10T09:29:07+00:00

commit afaa2e745a246c5ab95103a65b1ed00101e1bc63 upstream. In Bugzilla #208257, Julien Humbert reports that a 32-GB Kingston flash drive spontaneously disconnects and reconnects, over and over. Testing revealed that disabling Link Power Management for the drive fixed the problem. This patch adds a quirk entry for that drive to turn off LPM permanently.
