Convert over to the new NMI handling for getting IPMI watchdog timeouts via an NMI. This add config options to know if there is the ability to receive NMIs and if it has an NMI post processing call. Then it modifies the IPMI watchdog to take advantage of this so that it can know if an NMI comes in. It also adds testing that the IPMI NMI watchdog works.

Lockdep was giving an error when loading the IPMI watchdog module. It turns out that if you try to claim a lock in a parameter handling routine, lockdep won't see that lock as "static" yet because the module is not yet on the module list, so it will complain. However, the semaphore in question is completely unnecessary. So just remove it.

Patrick found a race at startup. Interrupts were being enabled for the IPMI interface before the driver was really ready to handle them. This could result in an oops if something was pending on the interface at startup and interrupt were already enabled (technically shouldn't happen, but need to cover for this in real life). So move the IRQ setup to the code that starts the actual IPMI processing.

There are cases when the filesystem will be passed the buffer from a single read or write call, namely: 1) in 'direct-io' mode (not O_DIRECT), read/write requests don't go through the page cache, but go directly to the userspace fs 2) currently buffered writes are done with single page requests, but if Nick's ->perform_write() patch goes it, it will be possible to do larger write requests. But only if the original write() was also bigger than a page. In these cases the filesystem might want to give a hint to the app about the optimal I/O size. Allow the userspace filesystem to supply a blksize value to be returned by stat() and friends. If the field is zero, it defaults to the old PAGE_CACHE_SIZE value.

Each WRITE request must carry a valid file descriptor. When a page is written back from a memory mapping, the file through which the page was dirtied is not available, so a new mechananism is needed to find a suitable file in ->writepage(s). A list of fuse_files is added to fuse_inode. The file is removed from the list in fuse_release(). This patch is in preparation for writable mmap support.

Getattr and lookup operations can be running in parallel to attribute changing operations, such as write and setattr. This means, that if for example getattr was slower than a write, the cached size attribute could be set to a stale value. To prevent this race, introduce a per-filesystem attribute version counter. This counter is incremented whenever cached attributes are modified, and the incremented value stored in the inode. Before storing new attributes in the cache, getattr and lookup check, using the version number, whether the attributes have been modified during the request's lifetime. If so, the returned attributes are not cached, because they might be stale. Thanks to Jakub Bogusz for the bug report and test program.

This patch set supports large block size(>4k, <=64k) in ext3 just enlarging the block size limit. But it is NOT possible to have 64kB blocksize on ext3 without some changes to the directory handling code. The reason is that an empty 64kB directory block would have a rec_len == (__u16)2^16 == 0, and this would cause an error to be hit in the filesystem. The proposed solution is treat 64k rec_len with a an impossible value like rec_len = 0xffff to handle this. The Patch-set consists of the following 2 patches. [1/2] ext3: enlarge blocksize - Allow blocksize up to pagesize [2/2] ext3: fix rec_len overflow - prevent rec_len from overflow with 64KB blocksize Now on 64k page ppc64 box runs with this patch set we could create a 64k block size ext3, and able to handle empty directory block.
