Pull staging/IIO driver updates from Greg KH:
 "Here is the big set of staging and IIO driver updates for 5.13-rc1.

  Lots of little churn in here, and some larger churn as well. Major
  things are:

   - removal of wimax drivers, no one has this hardware anymore for this
     failed "experiment".

   - removal of the Google gasket driver, turns out no one wanted to
     maintain it or cares about it anymore, so they asked for it to be
     removed.

   - comedi finally moves out of the staging directory into drivers/comedi

     This is one of the oldest kernel subsystems around, being created
     in the 2.0 kernel days, and was one of the first things added to
     drivers/staging/ when that was created over 15 years ago.

     It should have been moved out of staging a long time ago, it's well
     maintained and used by loads of different devices in the real world
     every day. Nice to see this finally happen.

   - so many tiny coding style cleanups it's not funny.

     Perfect storm of at least 2 different intern project application
     deadlines combined to provide a huge number of new contributions in
     this area from people learning how to do kernel development. Great
     job to everyone involved here.

  There's also the normal updates for IIO drivers with new IIO drivers
  and updates all over that subsystem.

  All of these have been in linux-next for a while with no reported
  issues"

 "Support for enhanced split lock detection:

  Newer CPUs provide a second mechanism to detect operations with lock

  these operations happen frequently.

  The new mechanism is not using the #AC exception. It triggers #DB and
  is restricted to operations in user space. Kernel side split lock
  access can only be detected by the #AC based variant.

  Contrary to the #AC based mechanism the #DB based variant triggers
  _after_ the instruction was executed. The mechanism is CPUID
  enumerated and contrary to the #AC version which is based on the magic
  TEST_CTRL_MSR and model/family based enumeration on the way to become
  architectural"

Pull entry code update from Thomas Gleixner:
 "Provide support for randomized stack offsets per syscall to make
  stack-based attacks harder which rely on the deterministic stack
  layout.

  The feature is based on the original idea of PaX's RANDSTACK feature,
  but uses a significantly different implementation.

  The offset does not affect the pt_regs location on the task stack as
  this was agreed on to be of dubious value. The offset is applied
  before the actual syscall is invoked.

  The offset is stored per cpu and the randomization happens at the end
  of the syscall which is less predictable than on syscall entry.

  The mechanism to apply the offset is via alloca(), i.e. abusing the
  dispised VLAs. This comes with the drawback that
  stack-clash-protection has to be disabled for the affected compilation
  units and there is also a negative interaction with stack-protector.

  Those downsides are traded with the advantage that this approach does
  not require any intrusive changes to the low level assembly entry
  code, does not affect the unwinder and the correct stack alignment is
  handled automatically by the compiler.

  The feature is guarded with a static branch which avoids the overhead
  when disabled.

  Currently this is supported for X86 and ARM64"

Pull irq updates from Thomas Gleixner:
 "The usual updates from the irq departement:

  Core changes:

   - Provide IRQF_NO_AUTOEN as a flag for request*_irq() so drivers can
     be cleaned up which either use a seperate mechanism to prevent
     auto-enable at request time or have a racy mechanism which disables
     the interrupt right after request.

   - Get rid of the last usage of irq_create_identity_mapping() and
     remove the interface.

   - An overhaul of tasklet_disable().

     Most usage sites of tasklet_disable() are in task context and
     usually in cleanup, teardown code pathes. tasklet_disable()
     spinwaits for a tasklet which is currently executed. That's not
     only a problem for PREEMPT_RT where this can lead to a live lock
     when the disabling task preempts the softirq thread. It's also
     problematic in context of virtualization when the vCPU which runs
     the tasklet is scheduled out and the disabling code has to spin
     wait until it's scheduled back in.

     There are a few code pathes which invoke tasklet_disable() from
     non-sleepable context. For these a new disable variant which still
     spinwaits is provided which allows to switch tasklet_disable() to a
     sleep wait mechanism. For the atomic use cases this does not solve
     the live lock issue on PREEMPT_RT. That is mitigated by blocking on
     the RT specific softirq lock.

   - The PREEMPT_RT specific implementation of softirq processing and
     local_bh_disable/enable().

     On RT enabled kernels soft interrupt processing happens always in
     task context and all interrupt handlers, which are not explicitly
     marked to be invoked in hard interrupt context are forced into task
     context as well. This allows to protect against softirq processing
     with a per CPU lock, which in turn allows to make BH disabled
     regions preemptible.

     Most of the softirq handling code is still shared. The RT/non-RT
     specific differences are addressed with a set of inline functions
     which provide the context specific functionality. The
     local_bh_disable() / local_bh_enable() mechanism are obviously
     seperate.

   - The usual set of small improvements and cleanups

  Driver changes:

   - New drivers for Nuvoton WPCM450 and DT 79rc3243x interrupt

Pull x509 dbx/mokx UEFI support from David Howells:
 "Here's a set of patches from Eric Snowberg[1] that add support for

  Additionally Eric included his patches to allow such certificates to
  be preloaded.

  These patches deal with CVE-2020-26541.

  To quote Eric:
       'This is the fifth patch series for adding support for
        EFI_CERT_X509_GUID entries [2]. It has been expanded to not only
        include dbx entries but also entries in the mokx. Additionally
