      [PATCH] block: disable block layer bouncing for most memory on 64bit systems · 5ee1af9f
      Andi Kleen authored
      The low level PCI DMA mapping functions should handle it in most cases.
      
      This should fix problems with depleting the DMA zone early. The old
      code used precious GFP_DMA memory in many cases where it was not needed.

      [PATCH] i386: port ATI timer fix from x86_64 to i386 II · f9262c12
      Andi Kleen authored
      ATI chipsets tend to generate double timer interrupts for the local APIC
      timer when both the 8254 and the IO-APIC timer pins are enabled.  This is
      because they route it to both and the result is anded together and the CPU
      ends up processing it twice.
      
      This patch changes check_timer to disable the 8254 routing for interrupt 0.
      
      I think it would be safe on all chipsets actually (i tested it on a couple
      and it worked everywhere) and Windows seems to do it in a similar way, but
      to be conservative this patch only enables this mode on ATI (and adds
      options to enable/disable too)
      
      Ported over from a similar x86-64 change.
      
      I reused the ACPI earlyquirk infrastructure for the ATI bridge check, but
      tweaked it a bit to work even without ACPI.
      
      Inspired by a patch from Chuck Ebbert, but redone.

      [NET] compat ifconf: fix limits · 1efa3c05
      Randy Dunlap authored
      A recent change to compat. dev_ifconf() in fs/compat_ioctl.c
      causes ifconf data to be truncated 1 entry too early when copying it
      to userspace.  The correct amount of data (length) is returned,
      but the final entry is empty (zero, not filled in).
      The for-loop 'i' check should use <= to allow the final struct
      ifreq32 to be copied.  I also used the ifconf-corruption program
      in kernel bugzilla #4746 to make sure that this change does not
      re-introduce the corruption.
