Patch from William Lee Irwin III <wli@holomorphy.com> This patch eliminates zap_hugetlb_resources, along with its usages. This actually fixes bugs, as zap_hugetlb_resources was itself buggy.

Patch from William Lee Irwin III <wli@holomorphy.com> Idle time accounting is disturbed by the iowait statistics, for several reasons: (1) iowait time is not subdivided among cpus. The only way the distinction between idle time subtracted from cpus (in order to be accounted as iowait) can be made is by summing counters for a total and dividing the individual tick counters by the proportions. Any tick type resolution which is not properly per-cpu breaks this, meaning that cpus which are entirely idle, when any iowait is present on the system, will have all idle ticks accounted to iowait instead of true idle time. (2) kstat_read_proc() misreports iowait time The idle tick counter is passed twice to the sprintf(), once in the idle tick position, and once in the iowait tick position. (3) performance enhancement The O(1) scheduler was very carefully constructed to perform accesses only to localized cachelines whenever possible. The global counter violates one of its core design principles, and the localization of "most" accesses is in greater harmony with its overall design and provides (at the very least) a qualitative performance improvement wrt. cache. The method of correcting this is simple: embed an atomic iowait counter in the runqueues, find the runqueue being manipulated in io_schedule(), increment its atomic counter prior to schedule(), and decrement it after returning from schedule(), which is guaranteed to be the same one, as the counter incremented is tracked as a variable local to the procedure. Then simply sum to obtain a global iowait statistic. (Atomicity is required as the post-wait decrement may occur on a different cpu from the one owning the counter.) io_schedule() and io_schedule_timeout() are moved to sched.c as they must access the runqueues, which are private to sched.c, and nr_iowait() is created in order to export the sum of all runqueues' nr_iowait().

A patch from Janet Morgan <janetmor@us.ibm.com> If you feed an iovec with a bad address not at the zeroeth segment into readv or writev, it returns the wrong value. iovec 1: base is 8050b20 len is 64 iovec 2: base is ffffffff len is 64 iovec 3: base is 8050ba0 len is 64 The writev should return 64 bytes but is returning 128 This is because we've added the new segment's length into `count' before running access_ok(). The patch changes it to fix that up on the slow path, if access_ok() fails.

DOH!!! Somebody clone me a replacement brain: I must have burnt another fuse. It turns out the new readpages was evading our read/write serialization. This broke things like 'ld' over NFS, which rewrites chunks of files it has already written.

I enhanced the sendfile method so that we could pass a proper actor to it (which exposes the full power of the internal implementation). Now knfsd calls the sendfile vector rather than depending on a readpage() that hasn't been set up fully.

Use new "nmi_enter/exit()" which acts the same as the regular irq entries (increases the preempt count appropriately), but doesn't try to start processing softirqs on nmi exit (it just decreases the count).

Given the previous set of patches that integrate NFS with the VM + pdflush memory control, and add mechanisms to cope with low memory conditions, the time is now ripe to rip out the 256 outstanding request limit, as well as the associated LRU list in the superblock, and the nfs_flushd daemon. The following patch offers a 30% speed increase on my test setup with 512MB of core memory (iozone using 4 threads each writing a 512MB file over 100Mbit to a Solaris server). Setting mem=64m, I still see a 2-3% speed increase.

In order to better cope with low memory conditions, add slabs for struct rpc_task and 'small' RPC buffers of <= 2k. Protect these using mempools. The only case where we appear to use buffers of > 2k is when symlinking, and is due to the fact that the path can be up to 4k in length. For the moment, we just use kmalloc(), but it may be worth it some time in the near future to convert nfs_symlink() to use pages.

Tiny cleanups in IDE...

Paul Mackerras authored
This removes two drivers from drivers/macintosh. The files affected are all in drivers/macintosh. First, the patch removes the old macintosh ADB keyboard driver and the macintosh keymap file, which are no longer used now that we use the input layer and the adbhid.c driver. Secondly, it removes the drivers/macintosh/rtc.c driver, which was only ever used on PPC, and which is obsolete now that we use the drivers/char/genrtc.c driver instead.

This updates the ADB driver and the three low-level ADB bus adaptor drivers used on powermacs. The files affected are all in drivers/macintosh; they are adb.c, macio-adb.c, via-cuda.c and via-pmu.c. The main changes in this patch are: - Remove the use of global cli/sti and replace them with local cli/sti, spinlocks and semaphores as appropriate. - Use DECLARE_WORK/schedule_work instead of tq_struct/schedule_task. - Improvements to the PMU interrupt handling and sleep/wakeup code.
