Linus Torvalds e1914add27 Arm:
* Add the pKVM side of the workaround for ARM's erratum 4193714, provided
   that the EL3 firmware does its part of the job. KVM will refuse to
   initialise otherwise.
 
 - Correctly handle 52bit VAs for guest EL2 stage-1 translations when
   running under NV with E2H==0.
 
 * Correctly deal with permission faults in guest_memfd memslots.
 
 * Fix the steal-time selftest after the infrastructure was reworked.
 
 * Make sure the host cannot pass a non-sensical clock update to the
   EL2 tracing infrastructure.
 
 * Appoint Steffen Eiden as a reviewer in anticipation of the KVM/s390
   ability to run arm64 guests, which will inevitably lead to arm64
   code being directly used on s390.
 
 * Make sure that EL2 is configured with both exception entry and exit
   being Context Synchronization Events.
 
 * Handle the current vcpu being NULL on EL2 panic.
 
 * Fix the selftest_vcpu memcache being empty at the point of donation or
   sharing.
 
 * Check that the memcache has enough capacity before engaging on the
   share/donate path.
 
 * Fix __deactivate_fgt() to use its parameter rather than a variable
   in the macro context.
 
 s390:
 
 * Fix array overrun with large amounts of PCI devices.
 
 x86:
 
 * Never use L0's PAUSE loop exiting while L2 is running, since it's
   unlikely that a nested guest will help solving the hypervisor's
   spinlock contention
 
 * Fix emulation of MOVNTDQA.
 
 * Fix typo in Xen hypercall tracepoint
 
 * Add back an optimization that was left behind when recently
   fixing a bug.
 
 * Add module parameter to disable CET, whose implementation seems
   to have issues.  For now it remains enabled by default.
 
 Generic:
 
 * Reject offset causing an unsigned overflow in kvm_reset_dirty_gfn()
 
 Documentation:
 
 * Update stale links
 
 Selftests:
 
 * Fix guest_memfd_test with host page size > guest page size.
