Instead of manually list each hypercall in arch/x86/xen/xen-head.S
use the auto generated symbol list.
This also corrects the wrong address of xen_hypercall_mca which was

Symbol addresses have been verified to match the correct ones via

The gas manual[1] suggests the syntax you've used for .type is invalid
and suggest using .type <name>, STT_FUNC
Really? In the link below I see:
The types supported are:
STT_FUNC
function
Mark the symbol as being a function name.

So "function" seems to be okay.

.balign PAGE_SIZE
You can remove this .balign.
