[PATCH] arm: restore ELR_hyp and SPSR_hyp on return from hypervisor to hypervisor.
This is necessary to handle nested traps to the hypervisor more than one deep.
I''ve not seen an actually failure relating to this but I''m not quite sure how
we''ve managed to get away with not doing it (I suppose multiply nested traps
are uncommon).

[PATCH 00/45] initial arm v8 (64-bit) support
First off, Apologies for the massive patch series...
This series boots a 32-bit dom0 kernel to a command prompt on an ARMv8
(AArch64) model. The kernel is the same one as I am currently using with
the 32 bit hypervisor
I haven''t yet tried starting a guest or anything super advanced like
that ;-). Also there is not real support for 64-bit domains at all,
although in one or two places I

arm: lr register in hyp mode is really LR_usr.
Save and restore it in the same way for both hypervisor and user stack frames
rather than saving both individually in the user stack frame.
