a188ad2 George G. Davis 02 September 2006, 17:43:20 UTC [ARM] 3762/1: Fix ptrace cache coherency bug for ARM1136 VIPT nonaliasing Harvard caches Patch from George G. Davis Resolve ARM1136 VIPT non-aliasing cache coherency issues observed when using ptrace to set breakpoints and cleanup copy_{to,from}_user_page() while we're here as requested by Russell King because "it's also far too heavy on non-v6 CPUs". NOTES: 1. Only access_process_vm() calls copy_{to,from}_user_page(). 2. access_process_vm() calls get_user_pages() to pin down the "page". 3. get_user_pages() calls flush_dcache_page(page) which ensures cache coherency between kernel and userspace mappings of "page". However flush_dcache_page(page) may not invalidate I-Cache over this range for all cases, specifically, I-Cache is not invalidated for the VIPT non-aliasing case. So memory is consistent between kernel and user space mappings of "page" but I-Cache may still be hot over this range. IOW, we don't have to worry about flush_cache_page() before memcpy(). 4. Now, for the copy_to_user_page() case, after memcpy(), we must flush the caches so memory is consistent with kernel cache entries and invalidate the I-Cache if this mm region is executable. We don't need to do anything after memcpy() for the copy_from_user_page() case since kernel cache entries will be invalidated via the same process above if we access "page" again. The flush_ptrace_access() function (borrowed from SPARC64 implementation) is added to handle cache flushing after memcpy() for the copy_to_user_page() case. Signed-off-by: George G.

3b98b08 Nishanth Aravamudan 01 September 2006, 04:27:53 UTC [PATCH] fix NUMA interleaving for huge pages Since vma->vm_pgoff is in units of smallpages, VMAs for huge pages have the lower HPAGE_SHIFT - PAGE_SHIFT bits always cleared, which results in badd offsets to the interleave functions. Take this difference from small pages into account when calculating the offset. This does add a 0-bit shift into the small-page path (via alloc_page_vma()), but I think that is negligible. Also add a BUG_ON to prevent the offset from growing due to a negative right-shift, which probably shouldn't be allowed anyways. Tested on an 8-memory node ppc64 NUMA box and got the interleaving I expected.

d565dd3 Benjamin Herrenschmidt 01 September 2006, 04:27:49 UTC [PATCH] powerpc: More via-pmu backlight fixes The via-pmu backlight code (introduced in 2.6.18) has various design issues causing crashes on machines using it like the old Wallstreet powerbook (Michael, the author, never managed to test on these and I just got my hand on one of those old beasts). This fixes them by no longer trying to hijack the backlight device of the frontmost framebuffer (causing that framebuffer to crash) but having it's own local bits instead. Might look weird but it's better that way on those old machines, at least as a last-minute fix for 2.6.18. We might rework the whole thing later. This patch also changes the way it gets notified of sleep and wakeup in order to properly shut the backlight down on sleep and bring it back on wakeup.

0b1d647 Pavel Mironchik 01 September 2006, 04:27:47 UTC [PATCH] dm: work around mempool_alloc, bio_alloc_bioset deadlocks This patch works around a complex dm-related deadlock/livelock down in the mempool allocator. Alasdair said: Several dm targets suffer from this. Mempools are not yet used correctly everywhere in device-mapper: they can get shared when devices are stacked, and some targets share them across multiple instances. I made fixing this one of the prerequisites for this patch: md-dm-reduce-stack-usage-with-stacked-block-devices.patch which in some cases makes people more likely to hit the problem. There's been some progress on this recently with (unfinished) dm-crypt patches at: http://www.kernel.org/pub/linux/kernel/people/agk/patches/2.6/editing/ (dm-crypt-move-io-to-workqueue.patch plus dependencies) and: I've no problems with a temporary workaround like that, but Milan Broz (a new Redhat developer in the Czech Republic) has started reviewing all the mempool usage in device-mapper so I'm expecting we'll soon have a proper fix for this associated problems. [He's back from holiday at the start of next week.] For now, this sad-but-safe little patch will allow the machine to recover.

35df17c Shailabh Nagar 01 September 2006, 04:27:38 UTC [PATCH] task delay accounting fixes Cleanup allocation and freeing of tsk->delays used by delay accounting. This solves two problems reported for delay accounting: 1. oops in __delayacct_blkio_ticks http://www.uwsg.indiana.edu/hypermail/linux/kernel/0608.2/1844.html Currently tsk->delays is getting freed too early in task exit which can cause a NULL tsk->delays to get accessed via reading of /proc/<tgid>/stats. The patch fixes this problem by freeing tsk->delays closer to when task_struct itself is freed up. As a result, it also eliminates the use of tsk->delays_lock which was only being used (inadequately) to safeguard access to tsk->delays while a task was exiting. 2. Possible memory leak in kernel/delayacct.c http://www.uwsg.indiana.edu/hypermail/linux/kernel/0608.2/1389.html The patch cleans up tsk->delays allocations after a bad fork which was missing earlier. The patch has been tested to fix the problems listed above and stress tested with rapid calls to delay accounting's taskstats command interface (which is the other path that can access the same data, besides the /proc interface causing the oops above).

df9ecab Christoph Lameter 01 September 2006, 04:27:35 UTC [PATCH] ZVC: Scale thresholds depending on the size of the system The ZVC counter update threshold is currently set to a fixed value of 32. This patch sets up the threshold depending on the number of processors and the sizes of the zones in the system. With the current threshold of 32, I was able to observe slight contention when more than 130-140 processors concurrently updated the counters. The contention vanished when I either increased the threshold to 64 or used Andrew's idea of overstepping the interval (see ZVC overstep patch). However, we saw contention again at 220-230 processors. So we need higher values for larger systems. But the current default is already a bit of an overkill for smaller systems. Some systems have tiny zones where precision matters. For example i386 and x86_64 have 16M DMA zones and either 900M ZONE_NORMAL or ZONE_DMA32. These are even present on SMP and NUMA systems. The patch here sets up a threshold based on the number of processors in the system and the size of the zone that these counters are used for. The threshold should grow logarithmically, so we use fls() as an easy approximation. Results of tests on a system with 1024 processors (4TB RAM) The following output is from a test allocating 1GB of memory concurrently on each processor (Forking the process. So contention on mmap_sem and the pte locks is not a factor): X MIN TYPE: CPUS WALL WALL SYS USER TOTCPU fork 1 0.552 0.552 0.540 0.012 0.552 fork 4 0.552 0.548 2.164 0.036 2.200 fork 16 0.564 0.548 8.812 0.164 8.976 fork 128 0.580 0.572 72.204 1.208 73.412 fork 256 1.300 0.660 310.400 2.160 312.560 fork 512 3.512 0.696 1526.836 4.816 1531.652 fork 1020 20.024 0.700 17243.176 6.688 17249.863 So a threshold of 32 is fine up to 128 processors. At 256 processors contention becomes a factor. Overstepping the counter (earlier patch) improves the numbers a bit: fork 4 0.552 0.548 2.164 0.040 2.204 fork 16 0.552 0.548 8.640 0.148 8.788 fork 128 0.556 0.548 69.676 0.956 70.632 fork 256 0.876 0.636 212.468 2.108 214.576 fork 512 2.276 0.672 997.324 4.260 1001.584 fork 1020 13.564 0.680 11586.436 6.088 11592.523 Still contention at 512 and 1020. Contention at 1020 is down by a third. 256 still has a slight bit of contention.

a302eb4 Christoph Lameter 01 September 2006, 04:27:34 UTC [PATCH] ZVC: Overstep counters Increments and decrements are usually grouped rather than mixed. We can optimize the inc and dec functions for that case. Increment and decrement the counters by 50% more than the threshold in those cases and set the differential accordingly. This decreases the need to update the atomic counters. The idea came originally from Andrew Morton.

However, for mem-full HCAs, these functions use the mthca_alloc() and mthca_free() bitmap helpers, and those helpers use non-IRQ-safe spin_lock() internally.

11012d4 Andi Kleen 30 August 2006, 17:37:06 UTC [PATCH] x86: Revert e820 MCFG heuristics The check for the MCFG table being reserved in the e820 map was originally added to detect a broken BIOS in a preproduction Intel SDV. However it also breaks the Apple x86 Macs, which can't supply this properly, but need a working MCFG. With this patch they wouldn't use the MCFG and not work. After some discussion I think it's best to remove the heuristic again. It also failed on some other boxes (although it didn't cause much problems there because old style port access for PCI config space still works as fallback), but the preproduction SDVs can just use pci=nommcfg. Supporting production machines properly is more important. Edgar Hucek did all the debugging work.

To fix this trigger path verification before setting a device into no-path state.

Use different kind of assignment to make sure gcc doesn't create code that creates temp variables on the stack, assigns values to it and copies the content of the whole temp variable to the destination.

467c378 Paul Mackerras 30 August 2006, 06:10:47 UTC [POWERPC] Fix irq enable/disable in smp_generic_take_timebase Eran Ben-Avi <eranpublic@yahoo.com> pointed out that the arch/ppc version of smp_generic_take_timebase disables interrupts on entry but exits without restoring them. However, both it and the arch/powerpc version have another problem, which is that they use local_irq_disable/enable rather than local_irq_save/restore, and they are called with interrupts disabled. This fixes both problems; it changes a return to a break in the arch/ppc version, and changes both versions to use local_irq_save/restore.

e0d872d Paul Mackerras 30 August 2006, 05:55:32 UTC [POWERPC] Fix problem with time not advancing on 32-bit platforms This fixes a problem introduced in 5db9fa9593e2ff69f2b95f9d59229dc4faaa564d. The last_jiffy per-cpu variable is only 32 bits on 32-bit machines, but it was being compared with a 64-bit quantity (tb_next_jiffy), which resulted in time not advancing. This fixes it by changing last_jiffy to be 64 bits on all platforms. With this, we no longer need tb_last_stamp as a 32-bit version of tb_last_jiffy, so this gets rid of tb_last_stamp and we just use tb_last_jiffy instead. This also fixes a bug when the boot cpu is not online, because using tb_last_stamp could have caused the wrong timebase origin value to be used when calculating the time of day.

7233593 Zang Roy-r61911 25 August 2006, 04:16:30 UTC [POWERPC] Support for "weird" MPICs and fixup mpc7448_hpc2 This adds a new hardware information table for mpic. This enables the mpic code to deal with mpic controllers with different register layouts and hardware behaviours. This introduces CONFIG_MPIC_WEIRD. For boards with non standard mpic controllers, select CONFIG_MPIC_WEIRD and add its hardware information in the mpic_infos[] array. TSI108/109 PIC takes the first index of weird hardware information table. :) The table can be extended. The Tsi108/109 PIC looks like standard OpenPIC but, in fact, is different in register mapping and behavior. The patch does not affect the behavior of standard mpic. If CONFIG_MPIC_WEIRD is not defined, the code is essentially identical to the current code. [benh@kernel.crashing.org: This patch is a slightly cleaned up version of Zang Roy's support for the TSI108 MPIC variant. It also fixes up MPC7448_hpc2 to use the new version of the type macros and changes the way MPIC is selected in Kconfig to better match what is done for other system devices. ] Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org> 30 August 2006, 04:29:42 UTC

47f2c36 David S. Miller 28 August 2006, 07:33:03 UTC [SPARC64]: Fix X server hangs due to large pages. This problem was introduced by changeset 14778d9072e53d2171f66ffd9657daff41acfaed Unlike the hugetlb code paths, the normal fault code is not setup to propagate PTE changes for large page sizes correctly like the ones we make for I/O mappings in io_remap_pfn_range(). It is absolutely necessary to update all sub-ptes of a largepage mapping on a fault. Adding special handling for this would add considerably complexity to tlb_batch_add(). So let's just side-step the issue and forcefully dirty any writable PTEs created by io_remap_pfn_range(). The only other real option would be to disable to large PTE code of io_remap_pfn_range() and we really don't want to do that. Much thanks to Mikael Pettersson for tracking down this problem and testing debug patches. Signed-off-by: David S. Miller <davem@davemloft.net> 30 August 2006, 04:23:31 UTC

This means other CPUs will be able to see the new address while it hasn't been initialized completely yet. One possible fix would be to grab the ifp->lock spinlock when creating the address struct; a simpler fix is to just move the assignment.
