b8b0f559c7 xen/apic/xenbus/swiotlb/pcifront/grant/tmem: Make functions or variables static.
There is no need for those functions/variables to be visible. Make them
static and also fix the compile warnings of this sort:

drivers/xen/<some file>.c: warning: symbol '<blah>' was not declared. Should it be static?

Some of them just require including the header file that
declares the functions.

ab6ec39a19 xen/apic: implement io apic read with hypercall
Implements xen_io_apic_read with hypercall, so it returns proper
IO-APIC information instead of fabricated one.

Fallback to return an emulated IO_APIC values if hypercall fails.

[v2: fallback to return an emulated IO_APIC values if hypercall fails]

31b3c9d723 xen/x86: Implement x86_apic_ops
Or rather just implement one different function as opposed
to the native one : the read function.

We synthesize the values.
