kaf24@firebug.cl.cam.ac.uk 3eaf2dff37 Remove TBF_SLOW_IRET hack from x86/64 Xen return-to-guest

Add comments in public header version.h to explain what all the different
feature flags mean. Add a new flag XENFEAT_pae_pgdir_above_4gb to inform the guest
that its PAE page directories do not need to conform to the usual hardware
restriction.

kaf24@firebug.cl.cam.ac.uk 224d655aba Whenever the slice of a domU is set to 0, sedf_adjdom() sets extraweight 
to 0.  Later, in desched_extra_dom(), if the extrawight is not set, the
vcpu's score is calculated with this:

 /*domain was running in L1 extraq => score is inverse of
   utilization and is used somewhat incremental!*/
   if ( !inf->extraweight )
       /*NB: use fixed point arithmetic with 10 bits*/
       inf->score[EXTRA_UTIL_Q] = (inf->period << 10) /
           inf->slice;

Which can result in a divide by zero.

This changeset adds a comments and additional sanity check to prevent this
case from crashing Xen.

emellor@leeni.uk.xensource.com d7f4473fae Adding a second IP address onto eth0 causes the vif-* hotplug scripts to 
fail: ip_of() is returning a LIST of IP addresses, one per line.
The vif-scripts attempt to use the list where single addresses ought to
be, with predictable results. This patch changes ip_of() to return
the first address in the list, which seems to be the first one configured.

Ian.Campbell@xensource.com a58703d1ed Add feature flag allowing guest kernel to run in domain 0. 
To support this we give kernel GDT entries DPL=0 and use kernel
segment selectors with RPL=0. Xen will crunch these to ring 1 when
they are passed in. When a segment selector is used directly or placed
in a stack frame the guest OS is reponsible for crunching the RPL.
