2f303b74a6 KVM: Convert kvm_lock back to non-raw spinlock
In commit e935b8372c ("KVM: Convert kvm_lock to raw_spinlock"),
the kvm_lock was made a raw lock.  However, the kvm mmu_shrink()
function tries to grab the (non-raw) mmu_lock within the scope of
the raw locked kvm_lock being held.  This leads to the following:

After the previous patch, kvm_lock need not be a raw spinlock anymore,
so change it back.

feaf0c7dc4 KVM: nVMX: Do not generate #DF if #PF happens during exception delivery into L2
If #PF happens during delivery of an exception into L2 and L1 also do
not have the page mapped in its shadow page table then L0 needs to
generate vmexit to L2 with original event in IDT_VECTORING_INFO, but
current code combines both exception and generates #DF instead. Fix that
by providing nVMX specific function to handle page faults during page
table walk that handles this case correctly.

851eb6677c KVM: nVMX: Do not put exception that caused vmexit to IDT_VECTORING_INFO
If an exception causes vmexit directly it should not be reported in
IDT_VECTORING_INFO during the exit. For that we need to be able to
distinguish between exception that is injected into nested VM and one that
is reinjected because its delivery failed. Fortunately we already have
mechanism to do so for nested SVM, so here we just use correct function
to requeue exceptions and make sure that reinjected exception is not
moved to IDT_VECTORING_INFO during vmexit emulation and not re-checked
for interception during delivery.

When the 'avr32_comparator' clockevent device is registered,
the clockevent core sets the mode of that clockevent device
to CLOCK_EVT_MODE_SHUTDOWN. Due to this, the 'comparator_mode'
function calls the 'cpu_idle_poll_ctrl' to disables idle poll.
This results in the aforementioned warning because the polling
is not enabled yet.

Change the code to only disable idle poll if it is enabled by
the same function to avoid the warning.

991e7ecf1f i2c: rcar: use per-device clock
Using the same clock for all device instances is non-portable and obtaining
clock references by an ID without using a device pointer is discouraged.
This is also not needed, because on platforms, where this driver is used,
suitable clocks are available for the I2C controllers, that are children of
the peripheral clock and just pass its rate 1-to-1 to controllers. This
patch switches the driver to obtain references to correct clocks.

71ac7f6255 apparmor: Use shash crypto API interface for profile hashes
Use the shash interface, rather than the hash interface, when hashing
AppArmor profiles. The shash interface does not use scatterlists and it
is a better fit for what AppArmor needs.

This fixes a kernel paging BUG when aa_calc_profile_hash() is passed a
buffer from vmalloc(). The hash interface requires callers to handle
vmalloc() buffers differently than what AppArmor was doing. Due to
vmalloc() memory not being physically contiguous, each individual page
behind the buffer must be assigned to a scatterlist with sg_set_page()
and then the scatterlist passed to crypto_hash_update().

The shash interface does not have that limitation and allows vmalloc()
and kmalloc() buffers to be handled in the same manner.

367156d9a8 NFS: Give "flavor" an initial value to fix a compile warning
The previous patch introduces a compile warning by not assigning an initial
value to the "flavor" variable.  This could only be a problem if the server
returns a supported secflavor list of length zero, but it's better to
fix this before it's ever hit.

Call nfs4_lookup_root_sec for each flavor returned by SECINFO_NO_NAME until
one works.

One example of a situation this fixes:

 - server configured for krb5
 - server principal somehow gets deleted from KDC
 - server still thinking krb is good, sends krb5 as first entry in
    SECINFO_NO_NAME response
 - client tries krb5, but this fails without even sending an RPC because
    gssd's requests to the KDC can't find the server's principal
