2.5.46-mm1

It wasn't clear whether it was useful or desirable to keep these patchsets
turning over.  But it will be helpful to keep them as a marshalling point
for people to see what is queued up, to get some additional testing and
stabilisation and for people to sync up against.  And also to keep things
like shared pagetables and dcache-rcu under test.

2.5.46-mm1 includes various fixes to things, Bill's hugetlb rework,
dcache-rcu and shared pagetables.

Also the patches which make the address_space's private_lock and page_lock
irq-safe.  So Badari can run set_page_dirty() from interrupts...

It's not supposed to be.  I'm guessing it's a conversion error in the move
to Kconfig.  A patch to fix it is attached.

It's definitely a benefit for all sizes of memory.

For what it's worth, the last mm kernel which booted on my old P-II IDE
test machine was 44-mm2. With 44-mm6 and this one I get an oops on boot.
Unfortunately it isn't written to disk, scrolls off the console, and
leaves the machine totally dead to anything less than a reset. I will try
2.5.46 base after I apply the few patches needed to make it compile, and
send you my config if you think it will help.

2.5.44 and all 4[45]-ac? builds booted and ran.

This is just a "problem present" notice, I have no decent info for
debugging.

Any chance of setting up a serial console? They're very handy for 
things like this ...

"vga=extended" gets you 50 rows, which is usually enough.

Depends if it keeps booting afterwards, or your pen skills are
just bad (like mine ;-))

Doesn't seem to do anything, nor does vga=773 which I remember from the
days of using VESA modes. Serial is definitely the one of choice, this
video card is not cooperating. I'll bring a cable from the office Monday.

Stock 2.5.46 does the same thing, but so did 44 and 44-ac? is running
happily. I'll look.

Certainly not with a real serial terminal ;-) As far as going through a
crossover cable to another system, it's doable, but finding the time, the
cable, etc... maybe next week. I just wanted to get the base report out in
case someone had more info, or if it was a known problem. 

I will try to capture it, but I'll try any new versions which come out
before then as well.
