From: Rusty Russell <rusty@rustcorp.com.au> From: Adam Kropelin <akropel1@rochester.rr.com> The new-and-improved kernel-locking kerneldoc seems to be missing some end tags which causes 'make foodocs' to die. I'm not sure if it's because of my not-bleeding-edge docbook utils or if it's a genuine error. Since most ending tags are present I tend to think it's an error.

From: Rusty Russell <rusty@rustcorp.com.au> Some places use cpu_online() where they should be using cpu_possible, most commonly for tallying statistics. This makes no difference without hotplug CPU. Use the for_each_cpu() macro in those places, providing good examples (and making the external hotplug CPU patch smaller).

From: Rusty Russell <rusty@rustcorp.com.au> Anton: breaks PPC64, as it needs cpu_possible_mask, but fix is already in Ameslab tree. The for_each_cpu() and for_each_online_cpu() iterators take a mask, and noone uses them that way (except for arch/i386/mach-voyager, which uses for_each_cpu(cpu_online_mask). Make them more usable iterators, by dropping the "mask" arg. This requires that archs provide a cpu_possible_mask: most do, but PPC64 doesn't, so it is broken by this patch. The other archs use a #define to define it in asm/smp.h. Most places doing loops over cpus testing for cpu_online() should use for_each_cpu: it is synonymous at the moment, but with the CPU hotplug patch the difference becomes important. Followup patches will convert users.

From: Con Kolivas <kernel@kolivas.org> A non-critical corner case has come up for interactivity that I believe needs to be addressed. It is only extensive testing and examination that revealed this, as this interactivity work is in maintenance mode. Description: It is possible for a highly interactive task (like X) to cause large latencies in tasks that are less 'niced' (eg negative nice number compared to X which should normally run at nice 0) if they are fully cpu bound. This occurs due to expiration of the cpu bound tasks. This patch addresses this by not reinserting interactive tasks into the active array if there is a better static priority task running but has been placed on the expired array. This causes a substantial reduction in the maximum scheduling latency a task with a less nice value can have. This also has the positive side effect of maintaining better cpu% proportions for tasks of different nice levels. Testers will only be able to discern a difference with highly cpu bound tasks of normal scheduling policy at different nice levels. Test cases are doing something cpu intensive relatively -niced in the presence of an interactive load (eg capturing and encoding video at nice -10 while using X nice 0, or something nice 0 vs nice +10) and so on. Because of the crossover of 10 'nice' levels of dynamic priorities between interactive and cpu bound tasks this patch will have a more noticable effect as the nice difference is greater, especially 11 or more.

From: Manfred Spraul <manfred@colorfullife.com> fasync_helper and kill_fasync are helpers for managing F_SETFL fcntl calls that change FASYNC and sending the necessary signals. The locking uses one global rwlock that's acquired for read in all kill_fasync calls, and that causes cache line trashing. This is not necessary: if the fasync list is empty, then there is no need to acquire the rwlock. Tests with reaim on a 4-way pIII on STP showed an 80% reduction of the time within kill_fasync.

From: Andres Salomon <dilinger@voxel.net> Remove calls to CardServices(); final. This removes the CardServices() calls the rest of the tree, as well as CardServices itself from cs.c and cs.h. My previous patches, along w/ Arjan's patch for ide-cs.c and Russell's patch for serial_cs.c should remove all traces of it. I've attached a gzipped tarball to hopefully make things easier.

From: Andres Salomon <dilinger@voxel.net> Replace the various CardServices() calls w/ their pcmcia_* function. The pcmcia functions fit better with kernel conventions, and don't have the nasty var args stuff. These patches also fix a few places where the args supplied to CardServices were either not supplied, or dealt with in non-obvious ways.

From: Rik van Riel <riel@surriel.com> In 2.6.0 both __alloc_pages() and the corresponding wakeup_kswapd()s walk all zones in the zone list, possibly spanning multiple nodes in a low numa factor system like AMD64. Also, if lower_zone_protection is set in /proc, then it may be possible that kswapd never cleans out data in zones further down the zonelist and try_to_free_pages needs to do that. However, in 2.6.0 try_to_free_pages() only frees pages in the pgdat the first zone in the zonelist belongs to. This is probably the wrong behaviour, since both the page allocator and the kswapd wakeup free things from all zones on the zonelist. The following patch makes try_to_free_pages() consistent with the allocator, by passing the zonelist as an argument and freeing pages from all zones in the list. I do not have any numa systems myself, so I have only tested it on my own little smp box. Testing on NUMA systems may be useful, though the patch really only should have an impact in those rare cases where kswapd can't keep up with allocations... As a side effect, the patch shrinks the kernel by 2 lines and replaces some subtle magic by a simpler array walk.

From: Paul Mackerras <paulus@samba.org> Since there are serial drivers (particularly the USB serial driver) that call the line discipline receive_buf and write_wakeup routines at hard interrupt level, I have changed the ppp_async code to cope with that. It now uses a tasklet so that it calls the generic PPP code at soft interrupt level even if its receive_buf and write_wakeup entries are called at hard interrupt level. This patch has been lightly tested here with a keyspan USB serial adaptor and also with the built-in modem on my tibook, which uses the pmac_zilog driver (which hooks into the drivers/serial infrastructure).
