      numa,sched: fix load_to_imbalanced logic inversion · 1662867a
      Rik van Riel authored
      This function is supposed to return true if the new load imbalance is
      worse than the old one.  It didn't.  I can only hope brown paper bags
      are in style.
      Now things converge much better on both the 4 node and 8 node systems.
      I am not sure why this did not seem to impact specjbb performance on the
      4 node system, which is the system I have full-time access to.
      This bug was introduced recently, with commit e63da036
      Allow task switch if load imbalance improves")

      Don't trigger congestion wait on dirty-but-not-writeout pages · b738d764
      Linus Torvalds authored
      shrink_inactive_list() used to wait 0.1s to avoid congestion when all
      the pages that were isolated from the inactive list were dirty but not
      under active writeback.  That makes no real sense, and apparently causes
      major interactivity issues under some loads since 3.11.
      The ostensible reason for it was to wait for kswapd to start writing
      pages, but that seems questionable as well, since the congestion wait
      code seems to trigger for kswapd itself as well.  Also, the logic behind
      delaying anything when we haven't actually started writeback is not
      clear - it only delays actually starting that writeback.
      We'll still trigger the congestion waiting if
       (a) the process is kswapd, and we hit pages flagged for immediate
       (b) the process is not kswapd, and the zone backing dev writeback is
           actually congested.
      This probably needs to be revisited, but as it is this fixes a reported

      arm, unwind, LLVMLinux: Enable clang to be used for unwinding the stack · e6b80757
      Mark Charlebois authored
      Patch to prevent warning of a buggy compiler when using clang and
      the ARM_UNWIND option.
      Clang defines (at least on the current trunk) GNUC, GNUC_MINOR, and
      GNUC_PATCHLEVEL to 4, 2, and 1 respectively.
      This version of GCC gets flagged as buggy, but it isn't actually an
      issue with clang so the patch will do what it did before unless clang
      is defined and then it will not report the GCC version as an issue.

      Mark Charlebois authored
      Replaced non-standard C use of Variable Length Arrays In Structs (VLAIS) in
      xt_repldata.h with a C99 compliant flexible array member and then calculated
      offsets to the other struct members. These other members aren't referenced by
      name in this code, however this patch maintains the same memory layout and
      padding as was previously accomplished using VLAIS.
      Had the original structure been ordered differently, with the entries VLA at
      the end, then it could have been a flexible member, and this patch would have
      been a lot simpler. However since the data stored in this structure is
      ultimately exported to userspace, the order of this structure can't be changed.
      This patch makes no attempt to change the existing behavior, merely the way in
      which the current layout is accomplished using standard C99 constructs. As such
      the code can now be compiled with either gcc or clang.
      This version of the patch removes the trailing alignment that the VLAIS
      structure would allocate in order to simplify the patch.

      x86/boot: EFI_MIXED should not prohibit loading above 4G · 745c5167
      Matt Fleming authored
      commit 7d453eee ("x86/efi: Wire up CONFIG_EFI_MIXED") introduced a
      regression for the functionality to load kernels above 4G. The relevant
      (incorrect) reasoning behind this change can be seen in the commit
        "The xloadflags field in the bzImage header is also updated to reflect
        that the kernel supports both entry points by setting both of
        XLF_CAN_BE_LOADED_ABOVE_4G is disabled so that the kernel text is
        guaranteed to be addressable with 32-bits."
      This is obviously bogus since 32-bit EFI loaders will never place the
      kernel above the 4G mark. So this restriction is entirely unnecessary.
      But things are worse than that - since we want to encourage people to
      always compile with CONFIG_EFI_MIXED=y so that their kernels work out of
      the box for both 32-bit and 64-bit firmware, commit 7d453eee
      effectively disables XLF_CAN_BE_LOADED_ABOVE_4G completely.
      Remove the overzealous and superfluous restriction and restore the
      XLF_CAN_BE_LOADED_ABOVE_4G functionality.
