* cpuset: remove sched domain hooks from cpusetsPaul Jackson2007-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the cpuset hooks that defined sched domains depending on the setting of the 'cpu_exclusive' flag. The cpu_exclusive flag can only be set on a child if it is set on the parent. This made that flag painfully unsuitable for use as a flag defining a partitioning of a system. It was entirely unobvious to a cpuset user what partitioning of sched domains they would be causing when they set that one cpu_exclusive bit on one cpuset, because it depended on what CPUs were in the remainder of that cpusets siblings and child cpusets, after subtracting out other cpu_exclusive cpusets. Furthermore, there was no way on production systems to query the result. Using the cpu_exclusive flag for this was simply wrong from the get go. Fortunately, it was sufficiently borked that so far as I know, almost no successful use has been made of this. One real time group did use it to affectively isolate CPUs from any load balancing efforts. They are willing to adapt to alternative mechanisms for this, such as someway to manipulate the list of isolated CPUs on a running system. They can do without this present cpu_exclusive based mechanism while we develop an alternative. There is a real risk, to the best of my understanding, of users accidentally setting up a partitioned scheduler domains, inhibiting desired load balancing across all their CPUs, due to the nonobvious (from the cpuset perspective) side affects of the cpu_exclusive flag. Furthermore, since there was no way on a running system to see what one was doing with sched domains, this change will be invisible to any using code. Unless they have real insight to the scheduler load balancing choices, they will be unable to detect that this change has been made in the kernel's behaviour. Initial discussion on lkml of this patch has generated much comment. My (probably controversial) take on that discussion is that it has reached a rough concensus that the current cpuset cpu_exclusive mechanism for defining sched domains is borked. There is no concensus on the replacement. But since we can remove this mechanism, and since its continued presence risks causing unwanted partitioning of the schedulers load balancing, we should remove it while we can, as we proceed to work the replacement scheduler domain mechanisms.

* flush icache before set_pte() on ia64: flush icache at set_pteKAMEZAWA Hiroyuki2007-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current ia64 kernel flushes icache by lazy_mmu_prot_update() *after* set_pte(). This is too late. This patch removes lazy_mmu_prot_update and add modfied set_pte() for flushing if necessary. This patch flush icache of a page when new pte has exec bit. && new pte has present bit && new pte is user's page. && (old *ptep is not present || new pte's pfn is not same to old *ptep's ptn) && new pte's page has no Pg_arch_1 bit. Pg_arch_1 is set when a page is cache consistent. I think this condition checks are much easier to understand than considering "Where sync_icache_dcache() should be inserted ?". pte_user() for ia64 was removed by http://lkml.org/lkml/2007/6/12/67 as clean-up. So, I added it again.

* Memoryless nodes: Use N_HIGH_MEMORY for cpusetsChristoph Lameter2007-10-16
| | | | | | | | | | | | | | | | | | | | | | cpusets try to ensure that any node added to a cpuset's mems_allowed is on-line and contains memory. The assumption was that online nodes contained memory. Thus, it is possible to add memoryless nodes to a cpuset and then add tasks to this cpuset. This results in continuous series of oom-kill and apparent system hang. Change cpusets to use node_states[N_HIGH_MEMORY] [a.k.a. node_memory_map] in place of node_online_map when vetting memories. Return error if admin attempts to write a non-empty mems_allowed node mask containing only memoryless-nodes.

* x86_64: SPARSEMEM_VMEMMAP 2M page size supportChristoph Lameter2007-10-16
| | | | | | | | | | | | | | | | | | | | | | x86_64 uses 2M page table entries to map its 1-1 kernel space. We also implement the virtual memmap using 2M page table entries. So there is no additional runtime overhead over FLATMEM, initialisation is slightly more complex. As FLATMEM still references memory to obtain the mem_map pointer and SPARSEMEM_VMEMMAP uses a compile time constant, SPARSEMEM_VMEMMAP should be superior. With this SPARSEMEM becomes the most efficient way of handling virt_to_page, pfn_to_page and friends for UP, SMP and NUMA on x86_64.

* slow down printk during bootRandy Dunlap2007-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | Optionally add a boot delay after each kernel printk() call, crudely measured in milliseconds, with a maximum delay of 10 seconds per printk. Enable CONFIG_BOOT_PRINTK_DELAY=y and then add (e.g.): "lpj=loops_per_jiffy boot_delay=100" to the kernel command line. It has been useful in cases like "during boot, my machine just reboots or the screen goes black" by slowing down printk, (and adding initcall_debug), we can usually see the last thing that happened before the lights went out which is usually a valuable clue.

These chips feature identical hardware monitoring capabilites with the expection that some of the fan inputs and pmw outputs don't exist. The hardware monitoring features of the SCH311x chips can only be accessed via the ISA bus. The driver therefore registers as a platform driver, if such a chip is detected.
