3e1d1d28d9 [PATCH] Cleanup patch for process freezing
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!

e3df715501 [SCSI] Remove unnecessary locking around completion function calls
The SCSI ->done() hook should not be called from inside a spinlock.

Drivers that do this are mostly cut-n-paste from 2.2.x-era.

a2ef79e184 [PATCH] sbp2 slab corruption fix
This fixed a problem that showed up in the Fedora development tree a few
weeks before the Fedora Core 4 release, initially as slab corruption, later
as hard crashes on boot up, when slab debugging was disabled for the
release.  More details on the history at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=158424

The problem is caused by sbp2's use of scsi_host->hostdata[0] to hold a
scsi_id, without explicitly requesting space for it.  Since hostdata is
declared as a zero-sized array, we don't get any such space by default, so
it must be explicitly requested.  The patch below implements just that.

631e8a1398 [SCSI] TYPE_RBC cache fixes (sbp2.c affected)
a) TYPE_SDAD renamed to TYPE_RBC and taken to scsi.h
	b) in sbp2.c remapping of TYPE_RPB to TYPE_DISK turned off
	c) relevant places in midlayer and sd.c taught to accept TYPE_RBC
	d) sd.c::sd_read_cache_type() looks into page 6 when dealing with
TYPE_RBC - these guys have writeback cache flag there and are not guaranteed
to have page 8 at all.
	e) sd_read_cache_type() got an extra sanity check - it checks that
it got the page it asked for before using its contents.  And screams if
mismatch had happened.  Rationale: there are broken devices out there that
are "helpful" enough to go for "I don't have a page you've asked for, here,
have another one".  For example, PL3507 had been caught doing just that...
	f) sbp2 sets sdev->use_10_for_rw and sdev->use_10_for_ms instead
of bothering to remap READ6/WRITE6/MOD_SENSE, so most of the conversions
in there are gone now.

	Incidentally, I wonder if USB storage devices that have no
mode page 8 are simply RBC ones.  I haven't touched that, but it might
be interesting to check...

e4ec0f23c8 [PATCH] Fix non-legacy ISO receive regression
Fix non-legacy multichannel ISO receive, broken by Parag Wardukar's
allocation fix.  Multichannel ISO receive still sucks; it should be possible
to use both legacy and non-legacy modes at the same time, but with this
patch, things are no worse than they were in 2.6.11 and allocation is
still done at the correct time.

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!
