scsi: megaraid_sas: Fix deadlock on firmware crashdump
a96d784 
[ Upstream commit 0b0747d507bffb827e40fc0f9fb5883fffc23477 ]

The following processes run into a deadlock. CPU 41 was waiting for CPU 29
to handle a CSD request while holding spinlock "crashdump_lock", but CPU 29
was hung by that spinlock with IRQs disabled.

The lock is used to synchronize different sysfs operations, it doesn't
protect any resource that will be touched by an interrupt. Consequently
it's not required to disable IRQs. Replace the spinlock with a mutex to fix
the deadlock.

scsi: target: core: Fix deadlock due to recursive locking
e5ccce2 
[ Upstream commit a154f5f643c6ecddd44847217a7a3845b4350003 ]

The following call trace shows a deadlock issue due to recursive locking of
mutex "device_mutex". First lock acquire is in target_for_each_device() and
second in target_free_device().

tun: limit printing rate when illegal packet received by tun dev
68459b8 
[ Upstream commit f8bbc07ac535593139c875ffa19af924b1084540 ]

vhost_worker will call tun call backs to receive packets. If too many
illegal packets arrives, tun_do_read will keep dumping packet contents.
When console is enabled, it will costs much more cpu time to dump
packet and soft lockup will be detected.

net_ratelimit mechanism can be used to limit the dumping rate.
