GAS of at least version 2.34 complains:
hypercall_page.S: Assembler messages:
hypercall_page.S:24: Warning: symbol 'HYPERCALL_set_trap_table' already has its type set
...
hypercall_page.S:71: Warning: symbol 'HYPERCALL_arch_7' already has its type set
This is because the whole page is declared as STT_OBJECT, and then every
hypercall within it is declared as STT_FUNC. As these are function-like and
in .text, retain the STT_FUNC type and drop STT_OBJECT.

Alternative suggestions welcome. I've got half a mind to strip the unused
hypercalls, as a large chunk of them are PV only and will never be used by a
PVH Xen. This would also remove the existing alias between hypercall_page and
HYPERCALL_set_trap_table.
