[Xen-devel] [PATCH 0/5] xen: arm: fix guest register access bug

[Ian Campbell <Ian.Campbell@xxxxxxxxxx>]

All the places where we currently access guest registers are subtly
broken, they always access the usr copy of a banked register regardless
of the guest VCPU mode. Luckily because fiq mode isn't used much this
mostly affects the SP and LR registers which are not typically used in
mmio instructions (which is most of the reason for this kind of
emulation). However the effect of hitting the bug is going to be some
pretty weird behaviour!

I've also included, mostly because they were in my branch and rebasing
things over them is a faff, some patches to clean up the tabs and line
lengths in entry.S.

Ian.
