[User-mode-linux-devel] Another batch

[Jeff D. <jd...@ka...>]

One more set of checkins before the next release.  This one makes the ubd 
driver fall back to synchronous I/O if it can't start the I/O thread.  The 
main reason this can happen is that the I/O thread communicates with the 
kernel with a pts pty, which can't be allocated by a normal user on sme 
distributions.  So, not having a backup plan would make uml unusable for those 
people without running as root.

I also changed arch/um/defconfig and bumped EXTRAVERSION in arch/um/Makefile.
