| * | [PATCH] powerpc: Kill _machine and hard-coded platform numbersBenjamin Herrenschmidt2006-03-281-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine.

| * | [PATCH] powerpc: Cope with duplicate node & property names in /proc/device-treeMichael Ellerman2006-03-281-23/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various dodgy firmware might give us nodes and/or properties in the device tree with conflicting names. That's generally ok, except for when we export the device tree via /proc, so check when we're creating the proc device tree and munge names accordingly. Tested on a faked device tree with kexec, would be good if someone with actual bogus firmware could try it, but just for completeness.

* | | [PATCH] convert sighand_cache to use SLAB_DESTROY_BY_RCUOleg Nesterov2006-03-281-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch borrows a clever Hugh's 'struct anon_vma' trick. Without tasklist_lock held we can't trust task->sighand until we locked it and re-checked that it is still the same. But this means we don't need to defer 'kmem_cache_free(sighand)'. We can return the memory to slab immediately, all we need is to be sure that sighand->siglock can't dissapear inside rcu protected section. To do so we need to initialize ->siglock inside ctor function, SLAB_DESTROY_BY_RCU does the rest.

* | | [PATCH] pidhash: kill switch_exec_pidsEric W. Biederman2006-03-281-3/+11

Currently switch_exec_pids gives the leader the pid of the thread and unhashes and rehashes all of the process groups. The leader is already in the EXIT_DEAD state so no one cares about it's pids. The only concern for the leader is that __unhash_process called from release_task will function correctly. If we don't touch the leader at all we know that __unhash_process will work fine so there is no need to touch the leader. For the task becomming the thread group leader, we just need to give it the pid of the old thread group leader, add it to the task list, and attach it to the session and the process group of the thread group. Currently de_thread is also adding the task to the task list which is just silly. Currently the only leader of __detach_pid besides detach_pid is switch_exec_pids because of the ugly extra work that was being performed. So this patch removes switch_exec_pids because it is doing too much, it is creating an unnecessary special case in pid.c, duing work duplicated in de_thread, and generally obscuring what it is going on. The necessary work is added to de_thread, and it seems to be a little clearer there what is going on. Signed-off-by: Eric W.

This means that we can change child_reaper earlier, without calling zap_other_threads() twice. "child_reaper = current" is a NOOP when init does exec from main thread, we don't care.

* | | [PATCH] exec: allow init to exec from any thread.Eric W. Biederman2006-03-281-1/+12
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After looking at the problem of init calling exec some more I figured out an easy way to make the code work. The actual symptom without out this patch is that all threads will die except pid == 1, and the thread calling exec. The thread calling exec will wait forever for pid == 1 to die. Since pid == 1 does not install a handler for SIGKILL it will never die. This modifies the tests for init from current->pid == 1 to the equivalent current == child_reaper. And then it causes exec in the ugly case to modify child_reaper. The only weird symptom is that you wind up with an init process that doesn't have the oldest start time on the box.

* | [PATCH] Optimize select/poll by putting small data sets on the stackAndi Kleen2006-03-281-42/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimize select and poll by a using stack space for small fd sets This brings back an old optimization from Linux 2.0. Using the stack is faster than kmalloc. On a Intel P4 system it speeds up a select of a single pty fd by about 13% (~4000 cycles -> ~3500) It also saves memory because a daemon hanging in select or poll will usually save one or two less pages. This can add up - e.g. if you have 10 daemons blocking in poll/select you save 40KB of memory. I did a patch for this long ago, but it was never applied. This version is a reimplementation of the old patch that tries to be less intrusive. I only did the minimal changes needed for the stack allocation. The cut off point before external memory is allocated is currently at 832bytes. The system calls always allocate this much memory on the stack. These 832 bytes are divided into 256 bytes frontend data (for the select bitmaps of the pollfds) and the rest of the space for the wait queues used by the low level drivers. There are some extreme cases where this won't work out for select and it falls back to allocating memory too early - especially with very sparse large select bitmaps - but the majority of processes who only have a small number of file descriptors should be ok. [TBD: 832/256 might not be the best split for select or poll] I suspect more optimizations might be possible, but they would be more complicated. One way would be to cache the select/poll context over multiple system calls because typically the input values should be similar. Problem is when to flush the file descriptors out though.

So we break that linkage and just do a second lookup. If this became a performance issue, it would be possible to put a direct link back in which was only used conditionally. i.e. when an object is replaced in the cache, we set a flag in the old object. When dereferencing the link from svc_expkey, if the flag is set, we drop the reference and do a fresh lookup.

| | | | | | | | | | | | | | | | | | | | | | | | This patch adds a follow_link inode method for the root of an autofs direct mount trigger. It also adds the corresponding mount options and updates the show_mount method.

* | [PATCH] autofs4: nameidata needs to be up to date for follow_linkIan Kent2006-03-271-18/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to be able to trigger a mount using the follow_link inode method the nameidata struct that is passed in needs to have the vfsmount of the autofs trigger not its parent. During a path walk if an autofs trigger is mounted on a dentry, when the follow_link method is called, the nameidata struct contains the vfsmount and mountpoint dentry of the parent mount while the dentry that is passed in is the root of the autofs trigger mount. I believe it is impossible to get the vfsmount of the trigger mount, within the follow_link method, when only the parent vfsmount and the root dentry of the trigger mount are known. This patch updates the nameidata struct on entry to __do_follow_link if it detects that it is out of date. It moves the path_to_nameidata to above __do_follow_link to facilitate calling it from there. The dput_path is moved as well as that seemed sensible. No changes are made to these two functions.
