speedtouch: turn a micro race into a nano race. The race is that an ATM device can be used the moment atm_dev_register returns, but you only get to fill out the atm_dev structure after atm_dev_register returns (this is a design flaw in the ATM layer). Thus there is a small window during which you can be called with an incompletely set up data structure. Workaround this by causing all ATM callbacks to fail if the dev_data field has not been set. There is still a nano race if writing/reading the dev_data field is not atomic. Is it atomic on all architectures?

speedtouch: rework udsl_usb_probe error handling (for example, handle failure of atm_dev_register). Do some trivial cleaning up while we're at it.

speedtouch: restore use of MODULE_DEVICE_TABLE to export usb info. There may have been a problem with older 2.4 kernels, but there is none now.

Someone changed the "get string" logic to use short reads, not long ones, a while back. That broke many root hub string accesses (not through tools like "lsusb"!) because that logic didn't handle short reads quite right.

__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.

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. /jeff

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

Please note that the naming DB is now completely optional. If there is no eisa.ids in the drivers/eisa/ directory, build will behave as if CONFIG_EISA_NAMES is disabled. So this patch can be left out if there is any objection.
