      Avoid false positive warnings in kmap_atomic_prot() with DEBUG_HIGHMEM · 9c312058
      Andrew Morton 提交于
      I believe http://bugzilla.kernel.org/show_bug.cgi?id=10318 is a false
      positive.  There's no way in which networking will be using highmem pages
      here, so it won't be taking the KM_USER0 kmap slot, so there's no point in
      performing these checks.

      RDMA/cxgb3: Program hardware IRD with correct value · 1f71f503
      Roland Dreier 提交于
      Because of a typo in iwch_accept_cr(), the cxgb3 connection handling
      code programs the hardware IRD (incoming RDMA read queue depth) with
      the value that is passed in for the ORD (outgoing RDMA read queue
      depth).  In particular this means that if an application passes in IRD
      > 0 and ORD = 0 (which is a completely sane and valid thing to do for
      an app that expects only incoming RDMA read requests), then the
      hardware will end up programmed with IRD = 0 and the app will fail in
      a mysterious way.
      
      Fix this by using "ep->ird" instead of "ep->ord" in the intended place.

      Revert commit 1192aeb9 ("ACPI:

      because it turns out that thermal_cooling_device_register() does

      turns into a dummy inline routine in the header files that returns NULL

      xen: fix UP setup of shared_info · 2e8fe719
      Jeremy Fitzhardinge 提交于
      We need to set up the shared_info pointer once we've mapped the real
      shared_info into its fixmap slot.  That needs to happen once the general
      pagetable setup has been done.  Previously, the UP shared_info was set
      up one in xen_start_kernel, but that was left pointing to the dummy
      shared info.  Unfortunately there's no really good place to do a later
      setup of the shared_info in UP, so just do it once the pagetable setup
      has been done.

      xen: fix RMW when unmasking events · 04c44a08
      Jeremy Fitzhardinge 提交于
      xen_irq_enable_direct and xen_sysexit were using "andw $0x00ff,
      XEN_vcpu_info_pending(vcpu)" to unmask events and test for pending ones
      in one instuction.
      
      Unfortunately, the pending flag must be modified with a locked operation
      since it can be set by another CPU, and the unlocked form of this
      operation was causing the pending flag to get lost, allowing the processor
      to return to usermode with pending events and ultimately deadlock.
      
      The simple fix would be to make it a locked operation, but that's rather
      costly and unnecessary.  The fix here is to split the mask-clearing and
      pending-testing into two instructions; the interrupt window between
      them is of no concern because either way pending or new events will
      be processed.
      
      This should fix lingering bugs in using direct vcpu structure access too.

      [IPSEC]: Fix BEET output · 732c8bd5
      Herbert Xu 提交于
      The IPv6 BEET output function is incorrectly including the inner
      header in the payload to be protected.  This causes a crash as
      the packet doesn't actually have that many bytes for a second
      header.
      
      The IPv4 BEET output on the other hand is broken when it comes
      to handling an inner IPv6 header since it always assumes an
      inner IPv4 header.
      
      This patch fixes both by making sure that neither BEET output
      function touches the inner header at all.  All access is now
      done through the protocol-independent cb structure.  Two new
      attributes are added to make this work, the IP header length
      and the IPv4 option length.  They're filled in by the inner
      mode's output function.
      
      Thanks to Joakim Koskela for finding this problem.

      This was tracked down to a potential livelock in
      return_unused_surplus_hugepages().  In the case where we have surplus
      pages on some node, but no free pages on the same node, we may never
      break out of the loop. To avoid this livelock, terminate the search if
      we iterate a number of times equal to the number of online nodes without
      freeing a page.
      
      Thanks to Andy Whitcroft and Adam Litke for helping with debugging and
      the patch.

      hugetlb: indicate surplus huge page counts in per-node meminfo · a1de0919
      Nishanth Aravamudan 提交于
      Currently we show the surplus hugetlb pool state in /proc/meminfo, but
      not in the per-node meminfo files, even though we track the information
      on a per-node basis. Printing it there can help track down dynamic pool
      bugs including the one in the follow-on patch.

      x86: fix performance drop for glx · d546b67a
      Suresh Siddha 提交于
      fix the 3D performance drop reported at:
      
         http://bugzilla.kernel.org/show_bug.cgi?id=10328
      
      fb drivers are using ioremap()/ioremap_nocache(), followed by mtrr_add with
      WC attribute. Recent changes in page attribute code made both
      ioremap()/ioremap_nocache() mappings as UC (instead of previous UC-). This
      breaks the graphics performance, as the effective memory type is UC instead
      of expected WC.
      
      The correct way to fix this is to add ioremap_wc() (which uses UC- in the
      absence of PAT kernel support and WC with PAT) and change all the
      fb drivers to use this new ioremap_wc() API.
      
      We can take this correct and longer route for post 2.6.25. For now,
      revert back to the UC- behavior for ioremap/ioremap_nocache.

      x86: fix trim mtrr not to setup_memory two times · 76c32418
      Yinghai Lu 提交于
      we could call find_max_pfn() directly instead of setup_memory() to get
      max_pfn needed for mtrr trimming.
      
      otherwise setup_memory() is called two times... that is duplicated...
      
      [ mingo@elte.hu: both Thomas and me simulated a double call to
        setup_bootmem_allocator() and can confirm that it is a real bug
        which can hang in certain configs. It's not been reported yet but
        that is probably due to the relatively scarce nature of
        MTRR-trimming systems. ]

      Er, yeah.  The patch below should fix it.  This should probably go into
      2.6.25.
      
      Oops, EXPORT_SYMBOL_GPL wasn't being declared due to this header
      being missing.
