[PATCH v2] clk: mvebu: armada-38x: add support for missing clocks

by Richard Genoud

Clearfog boards can come with a CPU clocked at 1600MHz (commercial) or 1333MHz (industrial). They have also some dip-switches to select a different clock (666, 800, 1066, 1200). The funny thing is that the recovery button is on the MPP34 fq selector. So, when booting an industrial board with this button down, the frequency 666MHz is selected (and the kernel didn't boot). This patch add all the missing clocks. The only mode I didn't test is 2GHz (uboot found 4294MHz instead :/ ).

[PATCH] tpm_tis: fix potential buffer overruns caused by bit glitches on the bus

by Jarkko Sakkinen

From: Jeremy Boone <jeremy.boone(a)nccgroup.trust> commit 2c0a646268f2a3536866bf237733a52aec260594 upstream Discrete TPMs are often connected over slow serial buses which, on some platforms, can have glitches causing bit flips. In all the driver _recv() functions, we need to use a u32 to unmarshal the response size, otherwise a bit flip of the 31st bit would cause the expected variable to go negative, which would then try to read a huge amount of data. Also sanity check that the expected amount of data is large enough for the TPM header.

[PATCH v2] block: Change a rcu_read_{lock, unlock}_sched() pair into rcu_read_{lock, unlock}()

by Bart Van Assche

scsi_device_quiesce() uses synchronize_rcu() to guarantee that the effect of blk_set_preempt_only() will be visible for percpu_ref_tryget() calls that occur after the queue unfreeze by using the approach explained in https://lwn.net/Articles/573497/. The rcu read lock and unlock calls in blk_queue_enter() form a pair with the synchronize_rcu() call in scsi_device_quiesce(). Both scsi_device_quiesce() and blk_queue_enter() must either use regular RCU or RCU-sched. Since neither the RCU-protected code in blk_queue_enter() nor blk_queue_usage_counter_release() sleeps, regular RCU protection is sufficient. Note: scsi_device_quiesce() does not have to be modified since it already uses synchronize_rcu().
