* e1000_irq_disable was used to disable irqs which called
  synchronize_irq which in turn caused a solid hang on SMP
  systems.

* Bug fix: TSO s/w workaround for premature desc write-back by h/w.  h/w
  was indicating desc done before DMA is complete, causing resources to
  be returned to OS too early.  Bad things happen then.
* Bug fix: Not time-stamping descriptors for fragmented sends.  Could 
  cause false hang-detection.
* Removed unecessary #ifdefs

rather than large static allocation on the stack

in tg3_enable_ints.

The bcm570x chips provide a register that disables (masks) or enables
interrupts, and as a side effect, each write to this register regardless 
of value clears various PCI and internal interrupt-pending flags.  This
register, intr-mbox-0, provides a superset of the function provided
by the mask-pci-int and clear-pci-int bits in the misc-host-ctrl register.

Furthermore, the documentation clearly implies use of this register,
as an indicator that the host [tg3 driver] is in its interrupt handler.

The new tg3 logic, taking this knowledge into account, masks-and-clears
irqs using intr-mbox-0 [only] when a hard irq is received, and
unmasks-and-clears irqs at the end of tg3_poll after all NAPI events
have been exhausted.

The old logic twiddled the misc-host-ctrl irq masking bits separately
from intr-mbox-0 bits, which was not only inconsistent but also
a few additional I/Os that were not needed.

The tg3_timer one is very likely superfluous, and will hopefully be
removed after extended testing.

* Removed /proc/net/PRO_LAN_Adapters
* Added ethtool GSTATS support

* Bug Fix: TCO workaround after hard reset of controller to wait for TCO
  traffic to settle.  Workaround requires issuing a CU load base command
  after hard reset, followed by a wait for scb and finally a wait for
  TCO traffic bit to clear.  Affects 82559s and above wired to SMBus.

__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.

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!

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

Add cfbfillrect / cfbcopyarea / cfbimgblt objects for SA1100fb.
Remove redundant "pm" member.

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 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 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 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.

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

From Jeff.Wiedemeier@hp.com:

Add platform-specific callin for SMP.

From Jeff.Wiedemeier@hp.com:

- Only create smp_affinity /proc nodes if a set_affinity handler
  is provided.
- Limit the number of irq nodes that will be created in /proc
  to avoid overfilling the /proc inode space.
