blaisorblade@yahoo.it b050ac70a8 [PATCH] uml: fix TT mode by reverting "use fork instead of clone"
From: Jeff Dike <jdike@addtoit.com>, Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

Revert the following patch, because of miscompilation problems in different
environments leading to UML not working *at all* in TT mode; it was merged
lately in 2.6 development cycle, a little after being written, and has caused
problems to lots of people; I know it's a bit too long, but it shouldn't have
been merged in first place, so I still apply for inclusion in the -stable
tree. Anyone using this feature currently is either using some older kernel
(some reports even used 2.6.12-rc4-mm2) or using this patch, as included in my
-bs patchset.

For now there's not yet a fix for this patch, so for now the best thing is to
drop it (which was widely reported to give a working kernel).

"Convert the boot-time host ptrace testing from clone to fork.  They were
essentially doing fork anyway.  This cleans up the code a bit, and makes
valgrind a bit happier about grinding it."
