      [ALPHA] New SRM console driver. · aca8e5a3
      Richard Henderson authored
      From Jeff Wiedemeier:
      
      How about this.. This version no longer piggy backs on ttyS0 (it
      actually doesn't touch any files outside arch/alpha/kernel at all). It
      does use a dynamic major for the tty piece of the driver. From
      userspace, /dev/console is ok for most uses, but because of the 'noctty
      = 1' at tty_tio.c:1329 (in the IS_SYSCONS_DEV section) using
      /dev/console cannot result in a controlling tty so some things, like
      'resize' and bash job control don't work. For those uses, however, it's
      easy enough to parse /proc/devices on the way up to get the major number
      and create the specific device for the tty side of the driver.
      
      I made a distinction in kernel options as well. "srmcons" specifically
      requests the early prints (as before) and "console=srm" requests the
      full driver, including the early prints. The two options can be
      combined with "console=srm" behavior resulting. The other change is that
      if "console=srm" is specified, I don't unregister_srm_console before
      console_init any more - that only happens in the "srmcons" case. That
      way preferred console selection remains stable and "console=srm" doesn't
      result in the early messages being repeated when the driver
      re-registers. The use of "srmcons_allowed" is also eliminated due to the
      "srmcons" vs. "console=srm" distinction.

      [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.

      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
