Anton Altaparmakov bfab36e816 NTFS: Fix a mount time deadlock.
Big thanks go to Mathias Kolehmainen for reporting the bug, providing
debug output and testing the patches I sent him to get it working.

The fix was to stop calling ntfs_attr_set() at mount time as that causes
balance_dirty_pages_ratelimited() to be called which on systems with
little memory actually tries to go and balance the dirty pages which tries
to take the s_umount semaphore but because we are still in fill_super()
across which the VFS holds s_umount for writing this results in a
deadlock.

We now do the dirty work by hand by submitting individual buffers.  This
has the annoying "feature" that mounting can take a few seconds if the
journal is large as we have clear it all.  One day someone should improve
on this by deferring the journal clearing to a helper kernel thread so it
can be done in the background but I don't have time for this at the moment
and the current solution works fine so I am leaving it like this for now.

Akinobu Mita b9a2838cc2 [PATCH] bitops: ntfs: remove generic_ffs()
Now the only user who are using generic_ffs() is ntfs filesystem.  This patch
isolates generic_ffs() as ntfs_ffs() for ntfs.

Anton Altaparmakov 5a8c0cc32b NTFS: More $LogFile handling fixes: when chkdsk has been run, it can leave the
restart pages in the journal without multi sector transfer protection
      fixups (i.e. the update sequence array is empty and in fact does not
      exist).

Anton Altaparmakov e7a1033b94 NTFS: Support more clean journal ($LogFile) states.
- Support journals ($LogFile) which have been modified by chkdsk.  This
        means users can boot into Windows after we marked the volume dirty.
        The Windows boot will run chkdsk and then reboot.  The user can then
        immediately boot into Linux rather than having to do a full Windows
        boot first before rebooting into Linux and we will recognize such a
        journal and empty it as it is clean by definition.
      - Support journals ($LogFile) with only one restart page as well as
        journals with two different restart pages.  We sanity check both and
        either use the only sane one or the more recent one of the two in the
        case that both are valid.

Anton Altaparmakov 3bd1f4a173 NTFS: Fix several occurences of a bug where we would perform 'var & ~const'
with a 64-bit variable and a int, i.e. 32-bit, constant.  This causes
      the higher order 32-bits of the 64-bit variable to be zeroed.  To fix
      this cast the 'const' to the same 64-bit type as 'var'.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
