      [PATCH] ppc64: fix initialisation of NUMA arrays · ef6574ff
      Andrew Morton authored
      From: Anton Blanchard <anton@samba.org>
      
      We were hitting problems on machines with cpu_possible != cpu_online when
      NUMA was enabled.  The debug checks would trip during scheduler init
      because we iterate through all possible cpus whereas we only set up NUMA
      information for online cpus.
      
      Longer term we should have a cpu_up hook which sets up its NUMA information
      but for now we initalise all possible cpus and memory to node 0.

      [PATCH] print kernel version in oops messages · dcdeeef8
      Andrew Morton authored
      From: Arjan van de Ven <arjanv@redhat.com>
      
      Unfortunatly a large portion of the oops reports lack the basic
      information about what kernel version the oops is for; it's trivial to just
      print this in the oops as well to improve the usefulness of bugreports...

      [PATCH] fix ppc64 in kernel syscalls · cb0cd969
      Anton Blanchard authored
      Thanks to some great debugging work by Olaf Hering and Marcus Meissner
      it has been noticed that the current ppc64 syscall code is corrupting
      4 bytes past errno. Why we even bothered to set errno beats me, its
      unusable in the kernel.
      
      Since we had to reinstate the inline syscall code we can go back to
      using it for those few syscalls that we call. Especially now with
      Randy's syscall prototype cleanup we should be calling them directly
      but we can do that sometime later.

      [PATCH] CDROMREADAUDIO dma support · f644f166
      Jens Axboe authored
      This small patch builds on top of the blk_rq_map_user() patch just sent,
      and enables us to easily support DMA for CDROMREADAUDIO cdda extraction.
      It's quite amazing how much cool stuff you can with the new block layer
      :-)
      
      Patch has intelligent fall back from multi frame dma to single frame
      dma, and further to old-style pio ripping in case of hardware problems.

      [PATCH] user data -> request mapping · 637b48c8
      Jens Axboe authored
      This patch allows you to map a request with user data for io, similarly
      to what you can do with bio_map_user() already to a bio. However, this
      goes one step further and populates the request so the user only has to
      fill in the cdb (almost) and put it on the queue for execution. Patch
      converts sg_io() to use it, next patch I'll send adapts cdrom layer to
      use it for zero copy cdda dma extraction.

      [PATCH] fix PPC64 iSeries virtual console devices · 95902cd8
      Stephen Rothwell authored
      While playing with udev, I discovered that the virtual console
      devices on iSeries had there minor numbers off by one i.e. /dev/tty1
      was minor 2!
      
      This fixes it.

      [PATCH] Fix a 64bit bug in kobject module request · 19c0199a
      Andi Kleen authored
      From Takashi Iwai
      
      kobj_lookup had a 64bit bug, which caused the request of a unknown
      character device to burn CPU instead of failing quickly.

      [PATCH] x86-64 merge for 2.6.4 · 7abe2c67
      Andi Kleen authored
      The biggest new feature is fixed 32bit vsyscall (SYSCALL+SYSENTER)
      support, mostly from Jakub Jelinek.  This increases 32bit syscall
      performance greatly (latency halved and better).  The SYSENTER for Intel
      support required some infrastructure changes, but seems to work now too.
      
      The 64bit vsyscall vtime() just references xtime.tv_sec now.  This
      should make it a lot faster too.
      
      A fix for some Intel IA32e systems.  Also a few long standing bugs in
      NMI like exception handlers were fixed.
      
      And a lot of other bug fixes.
      
      Full changeLog:
       - Clean up 32bit address room limit handling, fix 3gb personality
       - Move memcpy_{from,to}io export to ksyms.c file. This seems to work
         around a toolchain bug (Andreas Gruenbacher)
       - Update defconfig
       - ACPI merges from i386 (SBF should work now, acpi=strict)
       - Implement mmconfig support based on i386 code (untested)
       - Fix i386/x86-64 pci source file sharing
       - Implement ptrace access for 32bit vsyscall page
       - Always initialize all 32bit SYSENTER/SYSCALL MSRs.
       - Export run time cache line size to generic kernel
       - Remove explicit CPUID in ia32 syscall code
       - Fill in most of boot_cpu_data early
       - Remove unused PER_LINUX32 setup
       - Fix syscall trace in fast 32bit calls (Suresh B. Siddha)
       - Tighten first line of the oops again.
       - Set up ptrace registers correctly for debug,ss,double fault exceptions
       - Fix 64bit bug in sys_time64
       - Optimize time syscall/vsyscall to only read xtime
       - Fix csum_partial_copy_nocheck
       - Remove last traces of FPU emulation
       - Check properly for rescheduling in exceptions with own stack
       - Harden exception stack entries (#SS,#NMI,#MC,#DF,#DB) against bogus GS
       - Use an exception stack for machine checks
       - Handle TIF_SINGLESTEP properly in kernel exit
       - Add exception stack for debug handler
       - Disable X86_HT for Opteron optimized builds because it pulls in ACPI_BOOT
       - Fix CONFIG_ACPI_BOOT compilation without CONFIG_ACPI
       - Fix eflags handling in SYSENTER path (Jakub Jelinek)
       - Use atomic counter for enable/disable_hlt
       - Support 32bit SYSENTER vsyscall too (Jakub Jelinek)
       - Don't redefine Dprintk
       - Change some cpu/apic id arrays to char
       - Support arbitary cpu<->apicid in hard_smp_processor_id (Surresh B Sidda)
       - Move K8 erratum #100 workaround into slow path of page fault handler.
       - Fix 32bit cdrom direct access ioctls (Jens Axboe)
       - Enable 32bit vsyscalls by default
       - Fix 32bit vsyscalls (Jakub Jelinek)

      [PATCH] G5 temperature control update · 626942a4
      Benjamin Herrenschmidt authored
      This makes the temperature control code more robust, putting less
      pressure on i2c, and work around occasional misconfiguration of the ADC
      chips leading to incorrect temperature readings.

      [PATCH] Fix lockup accessing config space on G5 · a1ee5595
      Benjamin Herrenschmidt authored
      This patch fixes the code that workaround lockups when accessing
      the config space of devices on K2 when they are shut down. The
      code was there but in the wrong place ;) And a typo prevented the
      ohci1394 version of it from working.

      [PATCH] pcnet32.c oops · d57064b7
      Don Fry authored
      When adding an additional device, a variable which has been removed
      is accessed.  Adding the first device or a 4-port card works.
      Adding a second device was not done in PCI hot plug testing.  Now
      tested on IA32.

      Getting some blood sugar made the real fix for that become
      obvious! This replaces the preceding TEMPORARY hack.
      
      Only unlink EDs that aren't already being unlinked!

      [PATCH] USB: fix OHCI list corruption · b468eef0
      David Brownell authored
      Fix some OHCI TD list corruption issues:
      
          - Don't rewrite HC registers holding ED pointers until the HC
            had a good chance to finish using them.
      
          - Don't ever modify ed->hwTailP
      
      Adds text describing the different ED states.
      
      Adds TEMPORARY hack that may make a "rm_list becomes circular" bug
      continuable.

      Revert 8259 timer ack workaround · 87a5b745
      Linus Torvalds authored
      This patch was trying to work around buggy SMM bios but causes problems
      by not deasserting NMI irq line (reported by Thomas Schlicht) for some
      integrated local apic.
      
      This patch was written originally as an optimization (with the side
      effect to fix those bugged bios) but was never applied to 2.4 tree.
      
      The rational was: fix your bios instead.
