      [ARM] Fix Integrator __virt_to_bus/__bus_to_virt · 5c157415
      Russell King authored
      __virt_to_bus/__bus_to_virt depended on INTEGRATOR_HDR0_SDRAM_BASE
      Unfortunately, this is defined in arch-integrator/platform.h, and
      we really don't want to include it in memory.h.
      
      We instead use BUS_OFFSET, which will eventually depend on the CPU
      number in the system.

      [ARM/IDE] Fix BLK_DEV_IDEDMA setting on non-Acorn ARM systems · 4a78c70e
      Russell King authored
      Only default BLK_DEV_IDEDMA on BLK_DEV_IDEDMA_ICS if ARCH_ACORN is
      set, not if ARM is set.  There are PCI ARM systems out there!

      Russell King authored
      Ensure that we clean up properly after initialisation error,
      releasing all claimed resources in an orderly manner and
      returning the correct error code.

      [PATCH] Fix marvel irq count computation. · 7f5ea7bc
      Jeff Wiedemeier authored
      Found a buglet in the marvel code -- doesn't change the number of IRQS
      just the logic to get there.. This applies on top of the other marvel
      code.

      [PATCH] (3/3) NUMA rebalancer · 63ffe4d6
      Martin J. Bligh authored
      Patch from Erich Focht
      
      This adds a hook to rebalance globally across nodes every NODE_BALANCE_RATE
      iterations of the rebalancer. This allows us to easily tune on an architecture
      specific basis how often we wish to rebalance - machines with higher NUMA
      ratios (more expensive off-node access) will want to do this less often.
      It's currently set to 100 for NUMA-Q and 10 for other machines. If the
      imbalance between nodes is > 125%, we'll rebalance them. The hook for this
      is added to the NUMA definition of cpus_to_balance, so again, no impact
      on non-NUMA machines.

      [PATCH] (2/3) Initial load balancing · f01419fd
      Martin J. Bligh authored
      Patch from Michael Hohnbaum
      
      This adds a hook, sched_balance_exec(), to the exec code, to make it
      place the exec'ed task on the least loaded queue. We have less state
      to move at exec time than fork time, so this is the cheapest point
      to cross-node migrate. Experience in Dynix/PTX and testing on Linux
      has confirmed that this is the cheapest time to move tasks between nodes.
      
      It also macro-wraps changes to nr_running, to allow us to keep track of
      per-node nr_running as well. Again, no impact on non-NUMA machines.

      [PATCH] (1/3) Minimal NUMA scheduler · 5f24fe82
      Martin J. Bligh authored
      Patch from Martin J. Bligh
      
      This adds a small hook to the find_busiest_queue routine to allow us to
      specify a mask of which CPUs to search over. In the NUMA case, it will
      only balance inside the node (much cheaper to search, and stops tasks
      from bouncing across nodes, which is very costly). The cpus_to_balance
      routine is conditionally defined to ensure no impact to non-NUMA machines.
      
      This is a tiny NUMA scheduler, but it needs the assistance of the second
      and third patches in order to spread tasks across nodes.

      [PATCH] remove MOD_IN_USE · ca58c4b6
      Christoph Hellwig authored
      Another left-over from ancient module code, it was supposed to return
      non-zero if the module has a use count, but currently it always
      evaluates to 0.
      
      There are a few users of different types:
      (1)  ioctl that perform a while(MOD_IN_USE) MOD_DEC_USE_COUNT loop.
           Just rip them out, we now have forced module unloading.
      (2)  printk's that moan if the use-count in not zero in the exitfunc.
           Just rip them out, this can't happen.
      (3)  if(MOD_IN_USE) MOD_DEC_USE_COUNT constructs in ->close of a few
           serial drivers.  Just remove the conditional, we did a
           MOD_INC_USE_COUNT in ->open.
      (4)  This one is interesting:  drivers/sbus/char/display7seg.c uses
           the module use count to track openers.  Replace this with an
           atomic_t.
      
      In addition remove tons of stale comments in network driver that aren't
      understandable for anyone who doesn't know ancient Linux module semantics.

      [PATCH] x86_64 update · cf34d923
      Andi Kleen authored
      x86-64 updates for 2.5.58. Changes only x86-64 specific files.
      
       - Rewrote module allocation. Lots of bugs fixed. Module loading
         should work now again.
       - Kconfig help fixes from Randy Dunlap
       - Makefile cleanups from Pavel Machek and Sam Ravnborg
       - Assembly cleanups from Pavel
       - defconfig update
       - Better strlen_user/strnlen_user
       - Merge with i386: new ptrace commands, 32bit vsyscall signal trampolines
      		new deactivate_mm, add asm/bug.h
       - Make sure initramfs is freed after booting (thanks to Kai for the hint)
       - User per cpu data for profile counters (Ravikiran Thirumalai)
       - 32bit compat_* updates from Stephen Rothwell
       - Fix race in context switch. The exception handler for bogus segment
         loads in __switch_to needs to keep interrupts disabled, otherwise an
         interrupt can deadlock on scheduler locks.  Also make sure they don't
         printk or set oops_in_progress during printk because printk does a
         wake_up too.
       - Disable 64bit GS base changes for processes.  I cannot get it to work
         reliably.
       - Clear IOPL on kernel entry
