      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.

      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.
