* [PATCH] Add timestamp field to process eventsMatt Helsley2005-12-12
| | | | | | | | | | | | | | | | This adds a timestamp field to the events sent via the process event connector. The timestamp allows listeners to accurately account the duration(s) between a process' events and offers strong means with which to determine the order of events with respect to a given task while also avoiding the addition of per-task data. This alters the size and layout of the event structure and hence would break compatibility if process events connector as it stands in 2.6.15-rc2 were released as a mainline kernel.

* [PATCH] Add getnstimestamp functionMatt Helsley2005-12-12
| | | | | | | | | | | | | | | | | | | | | | | There are several functions that might seem appropriate for a timestamp: get_cycles() current_kernel_time() do_gettimeofday() <read jiffies/jiffies_64> Each has problems with combinations of SMP-safety, low resolution, and monotonicity. This patch adds a new function that returns a monotonic SMP-safe timestamp with nanosecond resolution where available.

* [PATCH] Fix listxattr() for generic security attributesDaniel Drake2005-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f549d6c18c0e8e6cf1bf0e7a47acc1daf7e2cec1 introduced a generic fallback for security xattrs, but appears to include a subtle bug. Gentoo users with kernels with selinux compiled in, and coreutils compiled with acl support, noticed that they could not copy files on tmpfs using 'cp'. cp (compiled with acl support) copies the file, lists the extended attributes on the old file, copies them all to the new file, and then exits. However the listxattr() calls were failing with this odd behaviour: llistxattr("a.out", (nil), 0) = 17 llistxattr("a.out", 0x7fffff8c6cb0, 17) = -1 ERANGE (Numerical result out of range) I believe this is a simple problem in the logic used to check the buffer sizes; if the user sends a buffer the exact size of the data, then its ok :) This change solves the problem.

* [PATCH] Fix RCU race in access of nohz_cpu_maskSrivatsa Vaddagiri2005-12-12
| | | | | | | | | | | | | | | Accessing nohz_cpu_mask before incrementing rcp->cur is racy. It can cause tickless idle CPUs to be included in rsp->cpumask, which will extend graceperiods unnecessarily. Fix this race. It has been tested using extensions to RCU torture module that forces various CPUs to become idle.

* [PATCH] add rcu_barrier() synchronization pointDipankar Sarma2005-12-12
| | | | | | | | | | | | | | | | | | | This introduces a new interface - rcu_barrier() which waits until all the RCUs queued until this call have been completed. Reiser4 needs this, because we do more than just freeing memory object in our RCU callback: we also remove it from the list hanging off super-block. This means, that before freeing reiser4-specific portion of super-block (during umount) we have to wait until all pending RCU callbacks are executed. The only change of reiser4 made to the original patch, is exporting of rcu_barrier(). Cc: Hans Reiser <reiser@namesys.com> Cc: Vladimir V.

* Allow arbitrary read-only shared pfn-remapping tooLinus Torvalds2005-12-11
| | | | | | | | | | | | | The VM layer (for historical reasons) turns a read-only shared mmap into a private-like mapping with the VM_MAYWRITE bit clear. Thus checking just VM_SHARED isn't actually sufficient. So use a trivial helper function for the cases where we wanted to inquire if a mapping was COW-like or not. Moo!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ppc64, when opening a new hugepage region, we need to make sure any old normal-page SLBs for the area are flushed on all CPUs. There was a bug in this logic - after putting the new hugepage area masks into the thread structure, we copied it into the paca (read by the SLB miss handler) only on one CPU, not on all. This could cause incorrect SLB entries to be loaded when a multithreaded program was running simultaneously on several CPUs. This patch corrects the error, copying the context information into the PACA on all CPUs using the mm in question before flushing any existing SLB entries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On most powerpc CPUs, the dcache and icache are not coherent so between writing and executing a page, the caches must be flushed. Userspace programs assume pages given to them by the kernel are icache clean, so we must do this flush between the kernel clearing a page and it being mapped into userspace for execute. We were not doing this for hugepages, this patch corrects the situation. We use the same lazy mechanism as we use for normal pages, delaying the flush until userspace actually attempts to execute from the page in question. Tested on G5.

However, icache_flush_range might be called before that, in slb_initialize()->patch_slb_encoding, which modifies the load immediate instructions used with SLB fault code. Not only that, but depending on memory layout, we might take SLB faults during unflatten_device_tree. So that fault will load an SLB entry that might not contain the right LLP flags for the segment. Either we can walk the flattened device tree to setup cache info, or we can pick the known defaults that are known to work. Doing it in the flattened device tree is hairier since we need to know the machine type to know what property to look for, etc, etc. For now, it's just easier to go with the defaults. Worst thing that happens from it is that we might waste a few cycles doing too small dcbst/icbi increments.

The reason for not allowing PMAC, PREP and CHRP to be selected individually for ARCH=ppc is that there is too much interdependency between them in the platform support code. For example, CHRP uses the PMAC nvram code. Configuring with ARCH=powerpc does allow you to select support for PMAC and CHRP separately. Support for PREP is not there yet but should be there soon.

Of course, I could force everybody to just use git (and when I'm emperor of the world, don't think I won't!), but it seems some people want to just test official releases. Even if they are just -rc's. By the time I'm back, Andrew will have fixed all my bugs, and I'll release it as 2.6.15 and take all the credit. Mwahahahaaa Signed-off-by: Linus Torvalds <torvalds@osdl.org>
