scsi: target: core: Fix deadlock due to recursive locking
eae6aab 
[ 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().

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.

tun: limit printing rate when illegal packet received by tun dev
eaa8c23 
[ 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.

mailbox: bcm2835: Fix timeout during suspend mode
4e1e037 
[ Upstream commit dc09f007caed3b2f6a3b6bd7e13777557ae22bfd ]

During noirq suspend phase the Raspberry Pi power driver suffer of
firmware property timeouts. The reason is that the IRQ of the underlying
BCM2835 mailbox is disabled and rpi_firmware_property_list() will always
run into a timeout [1].

Since the VideoCore side isn't consider as a wakeup source, set the
IRQF_NO_SUSPEND flag for the mailbox IRQ in order to keep it enabled
during suspend-resume cycle.
