UML 2.5.34

[Jeff Dike]

UML has been updated to 2.5.34 and UML 2.4.19-3.

There have been only a few minor changes since UML 2.5.33.  This is mostly an
update to 2.5.34.

The patch is available at
	http://uml-pub.ists.dartmouth.edu/uml/uml-patch-2.5.34-1.bz2

And this is a patch to make it compilable (not sure about
CLOCK_TICK_RATE and pte_addr_t parts though):

It even boots, great!

pte_addr_t and CLOCK_TICK_RATE were undefined.

Wrong macro in include/asm-um/percpu.h resulted in
include/asm-um/cacheflush.h never being included and a macros from the
latter undefined also.

By the way, I am talking about Linus BK tree, rather than patches you
have posted. Sorry for not mentioning this from the beginning.

Undefined WHERE?  You could send me a snippet of your build log.

I would not have sent it to Linus if it didn't build.  Like I said, it builds
here fine.  I want to know where it breaks, so I can see it for myself, so
I can be sure the fix is right.

It only just occurred to me that the breakage is likely due to stuff that
wasn't in 2.5.34, which I haven't seen yet since I haven't pulled the latest
Linus tree.

That being the case, thanks for the heads-up and the patch.

This isn't Jeff's fault. pte_addr_t is from pte-highmem bits I did
merged after he did his mergework.
