      IRQCHIP: mips-gic: Don't nest calls to do_IRQ() · 1b3ed367
      Rabin Vincent authored 
      The GIC chained handlers use do_IRQ() to call the subhandlers.  This
means that irq_enter() calls get nested, which leads to preempt count
looking like we're in nested interrupts, which in turn leads to all
system time being accounted as IRQ time in account_system_time().

Fix it by using generic_handle_irq().  Since these same functions are
used in some systems (if cpu_has_veic) from a low-level vectored
interrupt handler which does not go throught do_IRQ(), we need to do it
conditionally.

      sctp: allow authenticating DATA chunks that are bundled with COOKIE_ECHO · ae36806a
      Marcelo Ricardo Leitner authored 
      Currently, we can ask to authenticate DATA chunks and we can send DATA
chunks on the same packet as COOKIE_ECHO, but if you try to combine
both, the DATA chunk will be sent unauthenticated and peer won't accept
it, leading to a communication failure.

This happens because even though the data was queued after it was
requested to authenticate DATA chunks, it was also queued before we
could know that remote peer can handle authenticating, so
sctp_auth_send_cid() returns false.

The fix is whenever we set up an active key, re-check send queue for
chunks that now should be authenticated. As a result, such packet will
now contain COOKIE_ECHO + AUTH + DATA chunks, in that order.

      Pull block layer fixes from Jens Axboe:
 "Remember about a week ago when I sent the last pull request for 4.1?
  Well, I lied.  Now, I don't want to shift the blame, but Dan, Ming,
  and Richard made a liar out of me.

  Here are three small patches that should go into 4.1.  More
  specifically, this pull request contains:

   - A Kconfig dependency for the pmem block driver, so it can't be
     selected if HAS_IOMEM isn't availble.  From Richard Weinberger.

   - A fix for genhd, making the ext_devt_lock softirq safe.  This makes
     lockdep happier, since we also end up grabbing this lock on release
     off the softirq path.  From Dan Williams.

   - A blk-mq software queue release fix from Ming Lei.

  Last two are headed to stable, first fixes an issue introduced in this
  cycle"

      Pull three more md fixes from Neil Brown:
 "Hasn't been a good cycle for md has it :-(

  The main issue fixed here is a rare race which can result in two
  reshape threads running at once, which doesn't end well.

  Also a minor issue with a write to a sysfs file returning the wrong
  value.  Backports to 4.0-stable are indicated"

      Pull VT-d hardware workarounds from David Woodhouse:
 "This contains a workaround for hardware issues which I *thought* were
  never going to be seen on production hardware.  I'm glad I checked
  that before the 4.1 release...

  Firstly, PASID support is so broken on existing chips that we're just
  going to declare the old capability bit 28 as 'reserved' and change
  the VT-d spec to move PASID support to another bit.  So any existing
  hardware doesn't support SVM; it only sets that (now) meaningless bit
  28.

  That patch *wasn't* imperative for 4.1 because we don't have PASID
  support yet.  But *even* the extended context tables are broken — if
  you just enable the wider tables and use none of the new bits in them,
  which is precisely what 4.1 does, you find that translations don't
  work.  It's this problem which I thought was caught in time to be
  fixed before production, but wasn't.

  To avoid triggering this issue, we now *only* enable the extended
  context tables on hardware which also advertises "we have PASID
  support and we actually tested it this time" with the new PASID
  feature bit.

  In addition, I've added an 'intel_iommu=ecs_off' command line
  parameter to allow us to disable it manually if we need to"

* git://git.infradead.org/intel-iommu:
  iommu/vt-d: Only enable extended context tables if PASID is supported
  iommu/vt-d: Change PASID support to bit 40 of Extended Capability Register

      iommu/vt-d: Only enable extended context tables if PASID is supported · c83b2f20
      David Woodhouse authored 
      Although the extended tables are theoretically a completely orthogonal
feature to PASID and anything else that *uses* the newly-available bits,
some of the early hardware has problems even when all we do is enable
them and use only the same bits that were in the old context tables.

For now, there's no motivation to support extended tables unless we're
going to use PASID support to do SVM. So just don't use them unless
PASID support is advertised too. Also add a command-line bailout just in
case later chips also have issues.

The equivalent problem for PASID support has already been fixed with the
upcoming VT-d spec update and commit bd00c606 ("iommu/vt-d: Change
PASID support to bit 40 of Extended Capability Register"), because the
problematic platforms use the old definition of the PASID-capable bit,
which is now marked as reserved and meaningless.

So with this change, we'll magically start using ECS again only when we
see the new hardware advertising "hey, we have PASID support and we
actually tested it this time" on bit 40.

The VT-d hardware architect has promised that we are not going to have
any reason to support ECS *without* PASID any time soon, and he'll make
sure he checks with us before changing that.

In the future, if hypothetical new features also use new bits in the
context tables and can be seen on implementations *without* PASID support,
we might need to add their feature bits to the ecs_enabled() macro.
