[rcu] e183d26d07: BUG: using smp_processor_id() in preemptible [00000000] code: rcu_preempt/7
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git rcu/next
commit e183d26d072016428f2f05625c6724df4c573bef
Author: Paul E. McKenney <paulmck(a)linux.vnet.ibm.com>
AuthorDate: Wed Jan 25 15:28:49 2017 -0800
Commit: Paul E. McKenney <paulmck(a)linux.vnet.ibm.com>
CommitDate: Wed Jan 25 15:28:49 2017 -0800
rcu: Make rcu_all_qs() do deferred NOCB wakeups
If a CONFIG_RCU_NOCB_CPUS kernel invokes call_rcu() with interrupts
disabled, wakeups must be deferred in order to avoid self-deadlock in
the cases where the disabled interrupts are due to scheduler locks being
held. In this case, a flag is set and is checked on entry to extended
quiescent states (usermode, idle), on exit from the RCU_SOFTIRQ handler,
when the CPU in question goes offline, and on a subsequent invocation
of call_rcu(). However, a given CPU could avoid all of those states
for a considerable length of time.
This commit therefore allows an invocation of rcu_all_qs() to do the
wakeup. It also makes the wakeup function clear the deferred-wakeup flag.

[virtio_pci] 563d3bbe44: WARNING: CPU: 0 PID: 1 at kernel/irq/manage.c:1478 __free_irq
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git vhost
commit 563d3bbe444501ac1943d93c74f90460424e0af4
Author: Christoph Hellwig <hch(a)lst.de>
AuthorDate: Thu Nov 17 11:43:17 2016 +0100
Commit: Michael S. Tsirkin <mst(a)redhat.com>
CommitDate: Thu Dec 15 06:59:22 2016 +0200
virtio_pci: use shared interrupts for virtqueues
This lets IRQ layer handle dispatching IRQs to separate handlers for the
case where we don't have per-VQ MSI-X vectors, and allows us to greatly
simplify the code based on the assumption that we always have interrupt
vector 0 (legacy INTx or config interrupt for MSI-X) available, and
any other interrupt is request/freed throught the VQ, even if the
actual interrupt line might be shared in some cases.
This allows removing a great deal of variables keeping track of the
interrupt state in struct virtio_pci_device, as we can now simply walk the
list of VQs and deal with per-VQ interrupt handlers there, and only treat
vector 0 special. As a little caveat this means we have to check if VQs
have been set up before calling vp_synchronize_vectors, as otherwise
the initial reset will trip over the uninitialized ->vqs array.
