[PATCH 00/13] x86/paravirt: Make pv ops code generation more closely match reality
This changes the pv ops code generation to more closely match reality.
For example, instead of:
callq *0xffffffff81e3a400 (pv_irq_ops.save_fl)
vmlinux will now show:
pushfq
pop %rax
nop
nop
nop
nop
nop
which is what the runtime version of the code will show in most cases.
This idea was suggested by Andy Lutomirski.
The benefits are:
- For the most common runtime cases

Should I use gbde or geli?
Hello out there, everybody!
I was actually expecting to find several (hundred) threads with this
subject being discussed. To my surprise I didn't find a single one
either on these mailing lists or in the newsgroups - at least not in a
language I understand. :-)
I realize that gbde and geli are not designed to be better than the
other but that both fit different needs and different tastes.

Reflections on Trusting Trust
or "How do I know my copy of FreeBSD is the same as yours?"
I have recently been meditating on the issue of validating X.509
root certificates. An obvious extension to that is validating
FreeBSD itself.
Under "The Cutting Edge", the handbook lists 3 methods of
synchronising your personal copy of FreeBSD with the Project's copy:
Anonymous CVS, CTM and CVSup. There are
