+
+commit 8d5c30308d7c5a17db96fa5452c0232f633377c2 upstream.
+
+Clear the notify function pointer in the platform data before we tear
+down the driver. Otherwise i915 would end up calling a stale function
+pointer and possibly explode.

+The Atmel SHA driver was treating -EBUSY as indication of queueing

+Fix it by checking request flags.

+commit 7459e1d25ffefa2b1be799477fcc1f6c62f6cec7 upstream.
+
+Driver does not properly handle the case when signals interrupt
+wait_for_completion_interruptible():
+-it does not check for return value
+-completion structure is allocated on stack; in case a signal interrupts
+the sleep, it will go out of scope, causing the worker thread
+(caam_jr_dequeue) to fail when it accesses it
+
+wait_for_completion_interruptible() is replaced with uninterruptable
+wait_for_completion().
+We choose to block all signals while waiting for I/O (device executing
+the split key generation job descriptor) since the alternative - in
+order to have a deterministic device state - would be to flush the job
+ring (aborting *all* in-progress jobs).

+Subject: crypto: caam - properly set IV after {en,de}crypt
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: David Gstir <david@sigma-star.at>
+
+commit 854b06f768794cd664886ec3ba3a5b1c58d42167 upstream.
+
+Certain cipher modes like CTS expect the IV (req->info) of
+ablkcipher_request (or equivalently req->iv of skcipher_request) to
+contain the last ciphertext block when the {en,de}crypt operation is done.
+This is currently not the case for the CAAM driver which in turn breaks
+e.g. cts(cbc(aes)) when the CAAM driver is enabled.
+
+This patch fixes the CAAM driver to properly set the IV after the
+{en,de}crypt operation of ablkcipher finishes.
+
+This issue was revealed by the changes in the SW CTS mode in commit
+0605c41cc53ca ("crypto: cts - Convert to skcipher")

+
+The MSR permission bitmaps are shared by all VMs. However, some VMs
+may not be configured to support MPX, even when the host does. If the
+host supports VMX and the guest does not, we should intercept accesses
+to the BNDCFGS MSR, so that we can synthesize a #GP
+fault. Furthermore, if the host does not support MPX and the
+"ignore_msrs" kvm kernel parameter is set, then we should intercept
+accesses to the BNDCFGS MSR, so that we can skip over the rdmsr/wrmsr
+without raising a #GP fault.

+In the current code, if the user accidentally writes a bogus command to

+Subject: PM / wakeirq: Convert to SRCU
+
+From: Thomas Gleixner <tglx@linutronix.de>
+
+commit ea0212f40c6bc0594c8eff79266759e3ecd4bacc upstream.
+
+The wakeirq infrastructure uses RCU to protect the list of wakeirqs. That
+breaks the irq bus locking infrastructure, which is allows sleeping
+functions to be called so interrupt controllers behind slow busses,
+e.g. i2c, can be handled.
+
+The wakeirq functions hold rcu_read_lock and call into irq functions, which
+in case of interrupts using the irq bus locking will trigger a
+might_sleep() splat.
+
+Convert the wakeirq infrastructure to Sleepable RCU and unbreak it.

+Subject: sched/topology: Fix building of overlapping sched-groups
+
+From: Peter Zijlstra <peterz@infradead.org>
+
+commit 0372dd2736e02672ac6e189c31f7d8c02ad543cd upstream.
+
+When building the overlapping groups, we very obviously should start
+with the previous domain of _this_ @cpu, not CPU-0.
+
+This can be readily demonstrated with a topology like:
+
+ node 0 1 2 3
+ 0: 10 20 30 20
+ 1: 20 10 20 30
+ 2: 30 20 10 20
+ 3: 20 30 20 10
+
+Where (for example) CPU1 ends up generating the following nonsensical groups:
+
+ [] CPU1 attaching sched-domain:
+ [] domain 0: span 0-2 level NUMA
+ [] groups: 1 2 0
+ [] domain 1: span 0-3 level NUMA
+ [] groups: 1-3 (cpu_capacity = 3072) 0-1,3 (cpu_capacity = 3072)
+
+Where the fact that domain 1 doesn't include a group with span 0-2 is
+the obvious fail.
+
+With patch this looks like:
+
+ [] CPU1 attaching sched-domain:
+ [] domain 0: span 0-2 level NUMA
+ [] groups: 1 0 2
+ [] domain 1: span 0-3 level NUMA
+ [] groups: 0-2 (cpu_capacity = 3072) 0,2-3 (cpu_capacity = 3072)

+Subject: sched/topology: Fix overlapping sched_group_mask
+
+From: Peter Zijlstra <peterz@infradead.org>
+
+commit 73bb059f9b8a00c5e1bf2f7ca83138c05d05e600 upstream.
+
+The point of sched_group_mask is to select those CPUs from
+sched_group_cpus that can actually arrive at this balance domain.
+
+The current code gets it wrong, as can be readily demonstrated with a
+topology like:
+
+ node 0 1 2 3
+ 0: 10 20 30 20
+ 1: 20 10 20 30
+ 2: 30 20 10 20
+ 3: 20 30 20 10
+
+Where (for example) domain 1 on CPU1 ends up with a mask that includes
+CPU0:
+
+ [] CPU1 attaching sched-domain:
+ [] domain 0: span 0-2 level NUMA
+ [] groups: 1 (mask: 1), 2, 0
+ [] domain 1: span 0-3 level NUMA
+ [] groups: 0-2 (mask: 0-2) (cpu_capacity: 3072), 0,2-3 (cpu_capacity: 3072)
+
+This causes sched_balance_cpu() to compute the wrong CPU and
+consequently should_we_balance() will terminate early resulting in
+missed load-balance opportunities.
+
+The fixed topology looks like:
+
+ [] CPU1 attaching sched-domain:
+ [] domain 0: span 0-2 level NUMA
+ [] groups: 1 (mask: 1), 2, 0
+ [] domain 1: span 0-3 level NUMA
+ [] groups: 0-2 (mask: 1) (cpu_capacity: 3072), 0,2-3 (cpu_capacity: 3072)
+
+(note: this relies on OVERLAP domains to always have children, this is
+ true because the regular topology domains are still here -- this is
+ before degenerate trimming)
