It doesn't have the old PageReserved restrictions of remap_pfn_range(), and it doesn't complain about partial remappings. The page you insert needs to be a nice clean kernel allocation, so you can't insert arbitrary page mappings with this, but that's not what people want.

I've been able to (finally !) successfully suspend and resume various Mac models, with or without USB mouse plugged, or plugging while asleep, or unplugging while asleep etc... all without a crash. Alan, please verify the UHCI bit I did, I only verified that it builds. It's very simple so I wouldn't expect any issue there. If you aren't confident, then just drop the hunks that change uhci-hcd.c I also made the patch a little bit more "safer" by making sure the store to the interrupt register that disables interrupts is not posted before I set the flag and drop the spinlock. Without this patch, you cannot reliably sleep/wakeup any recent Mac, and I suspect PCs have some more sneaky issues too (they don't frankly crash with machine checks because x86 tend to silently swallow PCI errors but that won't last afaik, at least PCI Express will blow up in those situations, but the USB code may still misbehave).

| 18955cf | Mike Stroyan | 30 November 2005, 00:12:55 UTC | [IPV4] tcp/route: Another look at hash table sizes The tcp_ehash hash table gets too big on systems with really big memory. It is worse on systems with pages larger than 4KB. It wastes memory that could be better used. It also makes the netstat command slow because reading /proc/net/tcp and /proc/net/tcp6 needs to go through the full hash table. The default value should not be larger for larger page sizes. It seems that the effect of page size is an unintended error dating back a long time. I also wonder if the default value really should be a larger fraction of memory for systems with more memory. While systems with really big ram can afford more space for hash tables, it is not clear to me that they benefit from increasing the allocation ratio for this table. The amount of memory allocated is determined by net/ipv4/tcp.c:tcp_init and mm/page_alloc.c:alloc_large_system_hash. tcp_init calls alloc_large_system_hash passing parameters- bucketsize=sizeof(struct tcp_ehash_bucket) numentries=thash_entries scale=(num_physpages >= 128 * 1024) ? (25-PAGE_SHIFT) : (27-PAGE_SHIFT) limit=0 On i386, PAGE_SHIFT is 12 for a page size of 4K On ia64, PAGE_SHIFT defaults to 14 for a page size of 16K The num_physpages test above makes the allocation take a larger fraction of the total memory on systems with larger memory. The threshold size for a i386 system is 512MB. For an ia64 system with 16KB pages the threshold is 2GB. For smaller memory systems- On i386, scale = (27 - 12) = 15 On ia64, scale = (27 - 14) = 13 For larger memory systems- On i386, scale = (25 - 12) = 13 On ia64, scale = (25 - 14) = 11 For the rest of this discussion, I'll just track the larger memory case. The default behavior has numentries=thash_entries=0, so the allocated size is determined by either scale or by the default limit of 1/16 of total memory. In alloc_large_system_hash- | numentries = (flags & HASH_HIGHMEM) ? nr_all_pages : nr_kernel_pages; | numentries += (1UL << (20 - PAGE_SHIFT)) - 1; | numentries >>= 20 - PAGE_SHIFT; | numentries <<= 20 - PAGE_SHIFT; At this point, numentries is pages for all of memory, rounded up to the nearest megabyte boundary. | /* limit to 1 bucket per 2^scale bytes of low memory */ | if (scale > PAGE_SHIFT) | numentries >>= (scale - PAGE_SHIFT); | else | numentries <<= (PAGE_SHIFT - scale); On i386, numentries >>= (13 - 12), so numentries is 1/8196 of bytes of total memory. On ia64, numentries <<= (14 - 11), so numentries is 1/2048 of bytes of total memory. | log2qty = long_log2(numentries); | | do { | size = bucketsize << log2qty; bucketsize is 16, so size is 16 times numentries, rounded down to a power of two. On i386, size is 1/512 of bytes of total memory. On ia64, size is 1/128 of bytes of total memory. For smaller systems the results are On i386, size is 1/2048 of bytes of total memory. On ia64, size is 1/512 of bytes of total memory. The large page effect can be removed by just replacing the use of PAGE_SHIFT with a constant of 12 in the calls to alloc_large_system_hash. That makes them more like the other uses of that function from fs/inode.c and fs/dcache.c Signed-off-by: David S. Miller <davem@davemloft.net> | 30 November 2005, 00:12:55 UTC |

To do this, it retains state concerning how many slabs have been scanned - if a particular slab shrinker didn't scan enough objects, we remember that for next time, and scan more objects on the next pass. The problem with this is that with (say) a huge number of GFP_NOIO direct-reclaim attempts, the number of objects which are to be scanned when we finally get a GFP_KERNEL request can be huge. Because some shrinker handlers just bail out if !__GFP_FS. So the patch clamps the number of objects-to-be-scanned to 2* the total number of objects in the slab cache.

| 22dfdf5 | NeilBrown | 28 November 2005, 21:44:09 UTC | [PATCH] md: improve read speed to raid10 arrays using 'far copies' raid10 has two different layouts. One uses near-copies (so multiple copies of a block are at the same or similar offsets of different devices) and the other uses far-copies (so multiple copies of a block are stored a greatly different offsets on different devices). The point of far-copies is that it allows the first section (normally first half) to be layed out in normal raid0 style, and thus provide raid0 sequential read performance. Unfortunately, the read balancing in raid10 makes some poor decisions for far-copies arrays and you don't get the desired performance. So turn off that bad bit of read_balance for far-copies arrays. With this patch, read speed of an 'f2' array is comparable with a raid0 with the same number of devices, though write speed is ofcourse still very slow.

| 8c4b8ad | Paul Jackson | 28 November 2005, 21:44:05 UTC | [PATCH] cpuset fork locking fix Move the cpuset_fork() call below the write_unlock_irq call in kernel/fork.c copy_process(). Since the cpuset-dual-semaphore-locking-overhaul.patch, the cpuset_fork() routine acquires task_lock(), so cannot be called while holding the tasklist_lock for write.

| 3148890 | Nick Piggin | 28 November 2005, 21:44:03 UTC | [PATCH] mm: __alloc_pages cleanup fix I believe this patch is required to fix breakage in the asynch reclaim watermark logic introduced by this patch: http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=7fb1d9fca5c6e3b06773b69165a73f3fb786b8ee Just some background of the watermark logic in case it isn't clear... Basically what we have is this: --- pages_high | | (a) | --- pages_low | | (b) | --- pages_min | | (c) | --- 0 Now when pages_low is reached, we want to kick asynch reclaim, which gives us an interval of "b" before we must start synch reclaim, and gives kswapd an interval of "a" before it need go back to sleep. When pages_min is reached, normal allocators must enter synch reclaim, but PF_MEMALLOC, ALLOC_HARDER, and ALLOC_HIGH (ie. atomic allocations, recursive allocations, etc.) get access to varying amounts of the reserve "c".

| aa877b3 | Glauber de Oliveira Costa | 28 November 2005, 21:44:02 UTC | [PATCH] ext3: Wrong return value for EXT3_IOC_GROUP_ADD This patch corrects the return value for the EXT3_IOC_GROUP_ADD in case it fails due to the presence of multiple resizers at the filesystem. The problem is a little bit more serious than a wrong return value in this case, since the clause err=0 in the exit_journal path will lead to a call to update_backups which in turns causes a NULL pointer dereference.
