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.

__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 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
