SubjectLinux 2.6.7

Ok, it's out there. The most notable change may be the one-liner that
should fix the embarrassing FP exception problem. Other than that, we've
had a random collection of fixes and updates since rc3. cifs, ntfs,
cpufreq. ide, sparc, s390.

Full 2.6.6->2.6.7 changelog available at the same places the release is.

Linus

o fix modprobe_path and hotplug_path sizes and sysctl

Anil:
o speedup flush_workqueue for singlethread_workqueue
o flush_workqueue locking simplification

Anton Altaparmakov:
o NTFS: Implement writing of mft records (fs/ntfs/mft.[hc]), which
includes keeping the mft mirror in sync with the mft when mirrored
mft records are written. The functions are
write_mft_record{,_nolock}(). The implementation is quite
rudimentary for now with lots of things not implemented yet but I
am not sure any of them can actually occur so I will wait for
people to hit each one and only then implement it.
o NTFS: Commit open system inodes at umount time. This should make
it virtually impossible for sync_mft_mirror_umount() to ever be
needed.
o NTFS: Implement ->write_inode (fs/ntfs/inode.c::ntfs_write_inode())
for the ntfs super operations. This gives us inode writing via the
VFS inode dirty code paths. Note: Access time updates are not
implemented yet.
o NTFS: - Implement fs/ntfs/mft.[hc]::{,__}mark_mft_record_dirty()
and make fs/ntfs/aops.c::ntfs_writepage() and ntfs_commit_write()
use it, thus finally enabling resident file overwrite! (-8 This
also includes a placeholder for ->writepage (ntfs_mft_writepage()),
which for now just redirties the page and returns. Also, at umount
time, we for now throw away all mft data page cache pages after the
last call to ntfs_commit_inode() in the hope that all inodes will
have been written out by then and hence no dirty (meta)data will be
lost. We also check for this case and emit an error message
telling the user to run chkdsk.
o NTFS: Use set_page_writeback()/end_page_writeback() in
ntfs_writepage() resident attribute write code path as otherwise
the radix-tree tag PAGECACHE_TAG_DIRTY remains set even though the
page is clean.
o NTFS: Implement ntfs_mft_writepage() so it now checks if any of the
mft records in the page are dirty and if so redirties the page and
returns. Otherwise it just returns (after doing
set_page_writeback(), unlock_page(), end_page_writeback() or the
radix-tree tag PAGECACHE_TAG_DIRTY remains set even though the
page is clean), thus alowing the VM to do with the page as it
pleases. Also, at umount time, now only throw away dirty mft
(meta)data pages if dirty inodes are present and ask the user to
email us if they see this happening.
o NTFS: Add functions ntfs_{clear,set}_volume_flags(), to modify the
volume information flags (fs/ntfs/super.c).
o NTFS: 2.1.13 - Enable overwriting of resident files and
housekeeping of system files
o NTFS: 2.1.14 - Fix an NFSd caused deadlock reported by several
users

Dave Airlie:
o The dev->devname being passed to request_irq in drm_irq.h is null
o gamma_dma_priority and gamma_dma_send_buffers both deref
d->send_indices and/or d->send_sizes. When these functions are
called from gamma_dma, these pointers are user pointers and are
thus not safe to deref. This patch copies over the pointers inside
gamma_dma_priority and gamma_dma_send_buffers.
