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.

* 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.

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.

Until now, we were configuring all PCI resources from scratch. This patch allows to use unchanged PCI setup on platforms where the firmware does it reasonably well (titan and marvel). [The patch to setup-bus.c that removes "FIXME" from here (ie makes pci_assign_unassigned_resources to match its name) exists at least for two months, but I've yet to convince Linus that it does the right thing...] Ivan.
