2005-07-07[PATCH] ppc64: idle fixupsAnton Blanchard
- remove some unnecessary includes - add runlatch support - no need to use raw_smp_processor_id any more, current preempt debug logic checks for processes that are bound to one cpu.

2005-07-07[PATCH] ppc64: pSeries idle fixupsAnton Blanchard
- separate out sleep logic in dedicated_idle, it was so far indented that it got squashed against the right side of the screen. - add runlatch support, looping on runlatch disable.

2005-07-07[PATCH] ppc64: iSeries idle fixupsAnton Blanchard
- remove min/max yield time, we dont use the values anywhere - separate shared and dedicated idle loops - check need_resched again with irqs off to avoid sleeping with pending work - continually set runlatch off in idle loop, this means we dont need to turn the runlatch off on exception exit and suffer that associated cost for all exceptions. (A future patch will turn the runlatch on at exception entry) Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-07-07[PATCH] hvc_console: Rearrange codeMilton Miller
Milton Miller has done a lot of work to clean up our hvc_console code. One of the important things the following patch series does is separate the VIO layer from the hvc_console code. With the VIO specific code removed any ppc64 platform, or even any architecture, can use hvc_console as a generic polling console. You simply have to supply a get_chars and put_chars method and hvc_console does the rest of the work. You can even use it for an interrupt driven console. This patch: Rearrange the code in drivers/char/hvc_console.c to make future patches smaller. No actual code changes, just ordering of the functions in the file.

2005-07-07[PATCH] ppc64: Turn runlatch on in exception entryAnton Blanchard
Enable the runlatch at the start of each exception. Unfortunately we are out of space in the 0x300 handler, so I added it a bit later. The SPR write is fairly expensive, perhaps we should cache the runlatch state in the paca and avoid the write when possible. We don't need to turn the runlatch off, we do that in the idle loop. Better to take the hit in the idle loop than for each exception exit.

2005-07-07[PATCH] mm: quieten OOM killer noiseAnton Blanchard
We now print statistics when invoking the OOM killer, however this information is not rate limited and you can get into situations where the console is continually spammed. For example, when a task is exiting the OOM killer will simply return (waiting for that task to exit and clear up memory). If the VM continually calls back into the OOM killer we get thousands of copies of show_mem() on the console. Use printk_ratelimit() to quieten it.

2005-07-07[PATCH] export generic_drop_inode() to modulesMark Fasheh
OCFS2 wants to mark an inode which has been orphaned by another node so that during final iput it takes the correct path through the VFS and can pass through the OCFS2 delete_inode callback. Since i_nlink can get out of date with other nodes, the best way I see to accomplish this is by clearing i_nlink on those inodes at drop_inode time. Other than this small amount of work, nothing different needs to happen, so I think it would be cleanest to be able to just call generic_drop_inode at the end of the OCFS2 drop_inode callback.

Jesse Barnes provided the original version of this patch months ago, but other changes kept conflicting with it, so it got deferred. Greg Edwards dug it out of obscurity just over a week ago, and almost immediately another conflicting patch appeared (Bob Picco's memory-less nodes). I've resolved the conflicts and got it running again. CONFIG_SGI_TIOCX is set to "y" in defconfig, which causes a Tiger to not boot (oops in tiocx_init).

2005-07-06[PATCH] yet another fix for setup-bus.c/x86 mergeIvan Kokshaysky
There is a slight disagreement between setup-bus.c code and traditional x86 PCI setup wrt which recourses are invalid vs resources that are free for further allocations. In particular, in the setup-bus.c, if we failed to allocate some resource, we nullify "start" and "flags" fields, but *not* the "end" one. But x86 pcibios_enable_resources() does the following check: if (!r->start && r->end) { printk(KERN_ERR "PCI: Device %s not available because of resource collisions\n", pci_name(dev)); return -EINVAL; which means that the device owning the offending resource cannot be enabled. In particular, this breaks cardbus behind the normal decode p2p bridge - the cardbus code from setup-bus.c requests rather large IO and MEM windows, and if it fails, the socket is completely unavailable. Which is wrong, as the yenta code is capable to allocate smaller windows. Signed-off-by: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-07-06[IA64] memory-less-nodes repostbob.picco
I reworked how nodes with only CPUs are treated. The patch below seems simpler to me and has eliminated the complicated routine reassign_cpu_only_nodes. There isn't any longer the requirement to modify ACPI NUMA information which was in large part the complexity introduced in reassign_cpu_only_nodes. This patch will produce a different number of nodes. For example, reassign_cpu_only_nodes would reduce two CPUonly nodes and one memory node configuration to one memory+CPUs node configuration. This patch doesn't change the number of nodes which means the user will see three. Two nodes without memory and one node with all the memory. While doing this patch, I noticed that early_nr_phys_cpus_node isn't serving any useful purpose. It is called once in find_pernode_space but the value isn't used to computer pernode space.
