2006-03-08[PATCH] rcu batch tuningDipankar Sarma
This patch adds new tunables for RCU queue and finished batches. There are two types of controls - number of completed RCU updates invoked in a batch (blimit) and monitoring for high rate of incoming RCUs on a cpu (qhimark, qlowmark). By default, the per-cpu batch limit is set to a small value. If the input RCU rate exceeds the high watermark, we do two things - force quiescent state on all cpus and set the batch limit of the CPU to INTMAX. Setting batch limit to INTMAX forces all finished RCUs to be processed in one shot. If we have more than INTMAX RCUs queued up, then we have bigger problems anyway. Once the incoming queued RCUs fall below the low watermark, the batch limit is set to the default. Signed-off-by: Dipankar Sarma <dipankar@in.ibm.com> Cc: "Paul E.

2006-03-08[PATCH] percpu_counter_sum()Andrew Morton
Implement percpu_counter_sum(). This is a more accurate but slower version of percpu_counter_read_positive(). We need this for Alex's speedup-ext3_statfs patch and for the nr_file accounting fix. Otherwise these things would be too inaccurate on large CPU counts. Cc: Ravikiran G Thirumalai <kiran@scalex86.org> Cc: Alex Tomas <alex@clusterfs.com> Cc: "David S.

2006-03-08[PATCH] x86: Fix i386 nmi_watchdog that does not trigger die_nmiGOTO Masanori
Fix i386 nmi_watchdog that does not meet watchdog timeout condition. It does not hit die_nmi when it should be triggered, because the current nmi_watchdog_tick in arch/i386/kernel/nmi.c never count up alert_counter like this: void nmi_watchdog_tick (struct pt_regs * regs) { if (last_irq_sums[cpu] == sum) { alert_counter[cpu]++; <- count up alert_counter, but if (alert_counter[cpu] == 5*nmi_hz) die_nmi(regs, "NMI Watchdog detected LOCKUP"); alert_counter[cpu] = 0; <- reset alert_counter This patch changes it back to the previous and working version. This was found and originally written by Kohta NAKASHIMA.

2006-03-08[PATCH] udf: fix uid/gid options and add uid/gid=ignore and forget optionsPhillip Susi
Fix a bug in udf where it would write uid/gid = 0 to the disk for files owned by the id given with the uid=/gid= mount options. It also adds 4 new mount options: uid/gid=forget and uid/gid=ignore. Without any options the id in core and on disk always match. Giving uid/gid=nnn specifies a default ID to be used in core when the on disk ID is -1. uid/gid=ignore forces the in core ID to allways be used no matter what the on disk ID is. uid/gid=forget forces the on disk ID to always be written out as -1. The use of these options allows you to override ownerships on a disk or disable ownwership information from being written, allowing the media to be used portably between different computers and possibly different users without permissions issues that would require root to correct.

We're presently getting oopses because Bluetooth (and possibly other) drivers are calling core functions after things have been shut down.

2006-03-08powerpc: Fix various syscall/signal/swapcontext bugsPaul Mackerras
A careful reading of the recent changes to the system call entry/exit paths revealed several problems, plus some things that could be simplified and improved: * 32-bit wasn't testing the _TIF_NOERROR bit in the syscall fast exit path, so it was only doing anything with it once it saw some other bit being set. In other words, the noerror behaviour would apply to the next system call where we had to reschedule or deliver a signal, which is not necessarily the current system call. * 32-bit wasn't doing the call to ptrace_notify in the syscall exit path when the _TIF_SINGLESTEP bit was set. * _TIF_RESTOREALL was in both _TIF_USER_WORK_MASK and _TIF_PERSYSCALL_MASK, which is odd since _TIF_RESTOREALL is only set by system calls. I took it out of _TIF_USER_WORK_MASK. * On 64-bit, _TIF_RESTOREALL wasn't causing the non-volatile registers to be restored (unless perhaps a signal was delivered or the syscall was traced or single-stepped). Thus the non-volatile registers weren't restored on exit from a signal handler. We probably got away with it mostly because signal handlers written in C wouldn't alter the non-volatile registers. * On 32-bit I simplified the code and made it more like 64-bit by making the syscall exit path jump to ret_from_except to handle preemption and signal delivery. * 32-bit was calling do_signal unnecessarily when _TIF_RESTOREALL was set - but I think because of that 32-bit was actually restoring the non-volatile registers on exit from a signal handler. * I changed the order of enabling interrupts and saving the non-volatile registers before calling do_syscall_trace_leave; now we enable interrupts first.

Add DMA workaround for chips that do not support full 64-bit DMA addresses. 5714, 5715, and 5780 chips only support DMA addresses less than 40 bits. On 64-bit systems with IOMMU, set the dma_mask to 40-bit so that pci_map_xxx() calls will map the DMA address below 40 bits if necessary. On 64-bit systems without IOMMU, set the dma_mask to 64-bit and check for DMA addresses exceeding the limit in tg3_start_xmit(). 5788 only supports 32-bit DMA so need to set the mask appropriately also.

2006-03-06[PATCH] smaps: shared fixNick Piggin
The point of the smaps "shared" is to count the number of pages that are mapped by more than one process, according to Mauricio Lin. However, smaps uses page_count for this, so it will return a false positive for every page that is mapped by just that one process, which is also in pagecache or swapcache. There are false positive situations for anonymous pages not in swapcache as well: - page reclaim, migration - get_user_pages (eg. direct-io, ptrace) Use page_mapcount instead, to count the number of mappings to the page. Use vm_normal_page so that weird things like /dev/mem aren't counted either.

2006-03-06[PATCH] numa_maps updateChristoph Lameter
Change the format of numa_maps to be more compact and contain additional information that is useful for managing and troubleshooting memory on a NUMA system. Numa_maps can now also support huge pages. Fixes: 1. More compact format. Only display fields if they contain additional information. 2. Always display information for all vmas. The old numa_maps did not display vma with no mapped entries. This was a bit confusing because page migration removes ptes for file backed vmas. After page migration a part of the vmas vanished. 3. Rename maxref to maxmap. This is the maximum mapcount of all the pages in a vma and may be used as an indicator as to how many processes may be using a certain vma. 4. Include the ability to scan over huge page vmas. New items shown: dirty Number of pages in a vma that have either the dirty bit set in the page_struct or in the pte. file=<filename> The file backing the pages if any stack Stack area heap Heap area huge Huge page area. The number of pages shows is the number of huge pages not the regular sized pages. swapcache Number of pages with swap references. Must be >0 in order to be shown. active Number of active pages. Only displayed if different from the number of pages mapped. writeback Number of pages under writeback. Only displayed if >0.

2006-03-06[PATCH] Increase max kmalloc size for very large systemsJack Steiner
Systems with extemely large numbers of nodes or cpus need to kmalloc structures larger than is currently supported. This patch increases the maximum supported size for very large systems. This patch should have no effect on current systems. (akpm: why not just use alloc_pages() for sysfs_cpus?)

2006-03-06[PATCH] fix next_timer_interrupt() for hrtimerTony Lindgren
Also from Thomas Gleixner <tglx@linutronix.de> Function next_timer_interrupt() got broken with a recent patch 6ba1b91213e81aa92b5cf7539f7d2a94ff54947c as sys_nanosleep() was moved to hrtimer. This broke things as next_timer_interrupt() did not check hrtimer tree for next event. Function next_timer_interrupt() is needed with dyntick (CONFIG_NO_IDLE_HZ, VST) implementations, as the system can be in idle when next hrtimer event was supposed to happen. At least ARM and S390 currently use next_timer_interrupt().

2006-03-06[PATCH] x86: fix potential jiffies overflow in timer_resume()Atsushi Nemoto
i386 timer_resume is updating jiffies, not jiffies_64. It looks there is a potential overflow problem. And jiffies_64 and wall_jiffies should be protected by xtime_lock.

If the same ttyIx device was opened by two processes the module was not released and so the usage count went never to zero again. This oneliner fixes the issue.
