760559e133 [netdrvr 8139too] fast poll for thread, if an unlikely race occurs
The rtl8139 thread is triggered only on rare 8139 hardware, the race
itself is unlikely, and the impact of racing is low.  We don't care
enough to create a more-complex race-free solution.

Rather, if the trylock fails, we now simply poll twice a second until
we do get the lock.

a15e0384dd [netdrvr 8139too] replace hand-crafted kernel thread with workqueue
Gone are the days when 8139too was a shining example of how to use
kernel threads.  Delayed workqueues are easier, and map precisely to
our task:  running code from a kernel thread, after a periodic sleep.

7645baec58 [PATCH] 8139too: fix resume for Realtek 8100B/8139D
Add "HasHltClk" flag for RTL-8100B/8139D hardware in order to fix
problems resuming from suspend-to-RAM.

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!

22f714b64b [PATCH] 8139too: use iomap for pio/mmio
This patch converts the 8139too driver to use the iomap infrastructure
  for PIO and MMIO instead of playing macro tricks.  I also had to fix
  read_eeprom(), mdio_sync(), mdio_read(), and mdio_write() to not pass
  PIO base address to MMIO read() and write() functions.  In addition,
  the patch adds proper __iomem annotations for the driver.
  
  Both modes, PIO and MMIO, were tested with a RealTel RTL8139 card on
  an x86 box.  The 8129 support remains untested due to lack of
  hardware.

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!
