[PATCH 0/19] desc_struct integration
Hi,
this is a series of patches that unify the struct desc_struct and friends
across x86_64 and i386. As usual, it provides paravirt capabilities as a
side-effect for x86_64.
I consider the main goal, namely, of unifying the desc_struct, an ongoing
effort, being this the beginning. A lot of old code has to be touched to
accomplish that.
I don't consider this patch ready for inclusion.
