1. Establish a simple API for process freezing defined in linux/include/sched.h:

   frozen(process)		Check for frozen process
   freezing(process)		Check if a process is being frozen
   freeze(process)		Tell a process to freeze (go to refrigerator)
   thaw_process(process)	Restart process
   frozen_process(process)	Process is frozen now

2. Remove all references to PF_FREEZE and PF_FROZEN from all
   kernel sources except sched.h

3. Fix numerous locations where try_to_freeze is manually done by a driver

4. Remove the argument that is no longer necessary from two function calls.

5. Some whitespace cleanup

6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
   cleared before setting PF_FROZEN, recalc_sigpending does not check
   PF_FROZEN).

This patch does not address the problem of freeze_processes() violating the rule
that a task may only modify its own flags by setting PF_FREEZE. This is not clean
in an SMP environment. freeze(process) is therefore not SMP safe!

fs/jfs/jfs_logmgr.c: In function `jfs_flush_journal':
fs/jfs/jfs_logmgr.c:1632: warning: unused variable `mp'

Some debug code in jfs_flush_journal does nothing when CONFIG_JFS_DEBUG
is not defined.  Place the whole code segment within an ifdef to avoid
unnecessary code to be compiled and the warning to be issued.

This patch adds jfs_syncpt, which calls lmLogSync to write sync points
to the journal both in jfs_sync_fs and when sync barrier processing
completes.

lmLogSync accomplishes two things:  1) it pushes logged-but-dirty
metadata pages to disk, and 2) it writes a sync record to the journal
so that jfs_fsck doesn't need to replay more transactions than is
necessary.

jfs has never worked on architecutures where the page size was not 4K.

JFS code has always assumed a page size of 4K.  This patch fixes the
non-pagecache uses of pages to deal with larger pages.

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!
