Dominik Brodowski 819671ff84 syscalls: define and explain goal to not call syscalls in the kernel
The syscall entry points to the kernel defined by SYSCALL_DEFINEx()
and COMPAT_SYSCALL_DEFINEx() should only be called from userspace
through kernel entry points, but not from the kernel itself. This
will allow cleanups and optimizations to the entry paths *and* to
the parts of the kernel code which currently need to pretend to be
userspace in order to make use of syscalls.

Gregory CLEMENT 3cd2c313f1 dmaengine: mv_xor_v2: Fix clock resource by adding a register clock
On the CP110 components which are present on the Armada 7K/8K SoC we need
to explicitly enable the clock for the registers. However it is not
needed for the AP8xx component, that's why this clock is optional.

With this patch both clock have now a name, but in order to be backward
compatible, the name of the first clock is not used. It allows to still
use this clock with a device tree using the old binding.

Linus Torvalds a525df0558 powerpc fixes for 4.16 #5
One notable fix to properly advertise our support for a new firmware feature,
 caused by two series conflicting semantically but not textually.
 
 There's a new ioctl for the new ocxl driver, which is not a fix, but needed to
 complete the userspace API and good to have before the driver is in a released
 kernel.
 
 Finally three minor selftest fixes, and a fix for intermittent build failures
 for some obscure platforms, caused by a missing make dependency.
 
 Thanks to:
   Alastair D'Silva, Bharata B Rao, Guenter Roeck.

Tom Lendacky 801e459a6f KVM: x86: Add a framework for supporting MSR-based features
Provide a new KVM capability that allows bits within MSRs to be recognized
as features.  Two new ioctls are added to the /dev/kvm ioctl routine to
retrieve the list of these MSRs and then retrieve their values. A kvm_x86_ops
callback is used to determine support for the listed MSR-based features.

Guests on new hypersiors might set KVM_ASYNC_PF_DELIVERY_AS_PF_VMEXIT
bit when enabling async_PF, but this bit is reserved on old hypervisors,
which results in a failure upon migration.

To avoid breaking different cases, we are checking for CPUID feature bit
before enabling the feature and nothing else.

  cirrus:

  Lastly there is a deadlock fix around runtime suspend for secondary
  GPUs.

  There was a deadlock between one thread trying to wait for a workqueue
  job to finish in the runtime suspend path, and the workqueue job it
  was waiting for in turn waiting for a runtime_get_sync to return.

  The fixes avoids it by not doing the runtime sync in the workqueue as
  then we always wait for all those tasks to complete before we runtime
  suspend"

A single change (and associated DT binding update) to allow the address
 of the MIPS Cluster Power Controller (CPC) to be chosen by DT, which
 allows SMP to work on generic MIPS kernels where the bootloader hasn't

Will Deacon 61e02392d3 locking/atomic/bitops: Document and clarify ordering semantics for failed test_and_{}_bit()
A test_and_{}_bit() operation fails if the value of the bit is such that
the modification does not take place. For example, if test_and_set_bit()
returns 1. In these cases, follow the behaviour of cmpxchg and allow the
operation to be unordered. This also applies to test_and_set_bit_lock()
if the lock is found to be be taken already.
