      [PATCH] USB: usbcore misc cleanup (notably for non-dma hcds) · 31fd2ea0
      David Brownell authored
      The support for non-dma HCDs is likely the most interesting bit here.
      
          - makes dma calls behave sensibly when used with host controllers
            that don't use dma (including sl811).  usb_buffer_map() is a nop
            while scatterlist dma mappings fail (as they must).
      
          - make usb_sg_init() behave sensibly when used with non-dma hcs.
            the urbs are initted with transfer_buffer, not transfer_dma.
            this is the higher level analogue to usb_buffer_map(), so it
            needs to succeed unless there's a Real Error (tm).
      
          - moves two compatibility inlines from ehci.h into hcd.h so
            it'll be more practical to have the other hcds work in other
            environments (notably lk 2.4) too
      
          - remove URB_TIMEOUT_KILLED flag ... no device driver tests it;
            hcds don't really (uhci sets it, never reads it; sl811 doesn't
            enable the path that might set it), and it's not well defined.
            if any hcd needs such state, keep it in hc-private storage.
      
          - in usb_sg_wait(), use yield() instead of schedule() to let
            other activities free resources needed to continue.  (This
            was noted recently by Oliver.)

      [PATCH] USB ohci-hcd, don't force SLAB_ATOMIC allocations · fb4b62ad
      David Brownell authored
      This is a minor cleanup to let per-request memory allocations block,
      when the caller allows (it provided the bitmask).  The driver used
      to work that way until something like 2.4.3; an update (a few months
      back) to how the "dma_addr_t" hashes to a "struct ohci_td *" lets us
      simplify things again.  Another benfit:  it blocks irqs for less time
      on the submit path.  (The ehci driver already acts this way.)

      [PATCH] USB: pegasus & mii cset · 1fda844a
      Petko Manolov authored
        Some ethernet drivers other than those in .../drivers/net need generic
        MII code too and this cset shows how we do it for .../drivers/usb/net;
        For now only pegasus.c is using this feature, but as soon as we find
        more MII compliant controllers we'll put them in Makefile.mii too.
        Note: drivers which use the generic mii routines should bracket the
        code with #ifdef CONFIG_MII #endif since CONFIG_MII may not be present.
        See pegasus.c for more details.

      [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.

      [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
