Remove all the vio device driver code from hvc_console.c This will allow us to separate hvsi, hvc, and allow hvc_console to be used without the ppc64 vio layer. Signed-off-by:

Separate the console setup routines of the hvc_console and the vio layer. Remove the call to find_init_vty from hvc_console.c. Fail the setup routine if the console doesn't exist, but register the console again when the specified channel is instantiated. This scheme maintains the print buffer semantics while eliminating callout and call back for the console code. Signed-off-by:

Check if a vterm was registered before accepting it as a console. Check that a slot hasn't been probed with a tty in hvc_instantiate(). Check that a slot hasn't been free'ed when handing out console device. Signed-off-by:

Have the hvc console code try to pull characters immediately when receiving an interrupt, and kick the poll thread only if the immediate poll indicates it needed a call back to do more work. Signed-off-by:

Milton Miller authored
Use the vterm numbers to match the vio devices being probed with the indices already allocated via the console initcall function hvc_find_vtys. The old code required hvc_find_vtys to "guess" the matching devices the vio subsystem would find and its probe order. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

Using the syntax: make dir/module.ko kbuild now allows one to build a module including the final link stage. This is usefull when one only wants to compile a single module and thus do not have to wait until a full kernel has finished compiling. Tested by: randy_dunlap <rdunlap@xenotime.net> Signed-off-by:

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. Signed-off-by:

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). But that can be resolved later ... get this in now before it gets stale again. Signed-off-by: -

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:

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.
