The page allocator has traditionally just gone BUG when it sees a page in a bad state. This is usually due to hardware errors, sometimes software errors. I'm proposing that we not go BUG() any more, but print lots (and lots) of diagnostic info and try to continue. Might be a bit controversial.

balance_dirty_pages() is too expensive to call once-per-page. Use the ratelimited version.

From Dipanker Sarma. Before setting the ids->entries to the new array, there must be a wmb() to make sure that the memcpyed contents of the new array are visible before the new array becomes visible.

This patch fixes a problem which was discovered by Vladimir Saveliev <vs@namesys.com> Radix trees have a `height' field, which defines how far the pages are from the root of the tree. It starts out at zero and increases as the trees depth is grown. But it is never decreased. It cannot be decreased without a full tree traversal. Because radix_tree_delete() does not decrease `height', we end up returning inodes to their filesystem's inode slab cache with a non-zero height. And when that inode is reused from slab for a new file, it still has a non-zero height. So we're breaking the slab rules by not putting objects back in a fully reinitialised state. So the new file starts out life with whatever height the previous owner of the inode had. Which is space- and speed-inefficient. The most efficient place to fix this would be in destroy_inode(). But that only fixes the problem for inodes - there are other users of radix trees. So fix it in radix_tree_delete(): if the tree was emptied, reset `height' to zero.

Patch from Hugh Dickins <hugh@veritas.com> Fixes the Oracle startup problem reported by Alessandro Suardi. Reverts a "simplification" to shmdt() which was wrong if subsequent mprotects broke up the original VMA, or if parts of it were munmapped.

- I hit a BUG in end_swap_bio_read() under heavy load. The page wasn't locked. No idea how this can happen :( Add a BUG at submission time to catch a caller reading into an unlocked swapcache page. - Remove a debug check from destroy_inode() - it was in the wrong leg of the `if' statement anyway.

This allows NFSv4 responses to cover move than one page. There are still limits though. There can be at most one 'data' response which includes READ, READLINK, READDIR. For these responses, the interesting data goes in a separate page or, for READ, list of pages. All responses before the 'data' response must fit in one page, and all responses after it must also fit in one (separate) page.

Now that nfsd uses a list of pages for requests instead of one large buffer, NFSv4 need to know about this. The most interesting part of this is that it is possible that section of a request, like a path name, could span two pages, so we need to be able to kmalloc as little bit of space to copy them into, and make sure they get freed later.

We don't implement the ancient stat syscalls on ppc64 since early libcs wont run on ppc64 (they hardcode the incorrect cacheline size).

Here is the a pre-patch in the attempt to get rid of 'struct nfs4_compound', and the associated horrible union in 'struct nfs4_op'. It splits out the fields that are meant to do buffer overflow checking and iovec adjusting on the XDR received/sent data. It moves support for that nto the dedicated structure 'xdr_stream', and the associated functions 'xdr_reserve_space()', 'xdr_inline_decode()'. The patch also expands out the all macros ENCODE_HEAD, ENCODE_TAIL, ADJUST_ARGS and DECODE_HEAD, as well as most of the DECODE_TAILs.

This changes the return type of the verify and setpolicy functions from void to int. While doing this, I've changed the values for minimum and maximum supported frequency to be per CPU, as UltraSPARC needs this. Additionally, small cleanups in various drivers.

Traditional naming in pci/setup-xx code assumes that pdev_*/pbus_* functions are private, everything visible from outer world should be pci_*.

The most important changes are: - allocate buffers on open(), not module load; - correct some failed allocation paths; - use wait_event; - C99 structs inits;

The most important changes are: * add suspend/resume support to the sonypi driver (not based on driverfs however) (Florian Lohoff); * add "Zoom" and "Thumbphrase" buttons (Francois Gurin); * add camera and lid events for C1XE (Kunihiko IMAI); * add a mask parameter letting the user choose what kind of events he wants; * use ACPI ec_read/ec_write when available in order to play nice when latest ACPI is enabled; * several source cleanups.

Today we return EINVAL for fcntl with a lock with negative length. POSIX-2001 says that the lock covers start .. start+len-1 if len >= 0 and start+len .. start-1 if len < 0.

The i_dev field is deleted and the few uses are replaced by i_sb->s_dev. There is a single side effect: a stat on a socket now sees a nonzero st_dev. There is nothing against that - FreeBSD has a nonzero value as well - but there is at least one utility (fuser) that will need an update.
