If you're going to do that, use inline functions pls so that it checks
the argument at least.
Also, add such functions only when they're called multiple times - no
need to add one for every field if you're going to access that field
only once in the whole kernel.

Why alert?
Dumping stuff is either pr_debug or pr_info...

This is going to confuse people because they're going to miss a zero
entry. Just dump the whole thing.

Eww.
I'd prefer to see
pfn = dump_pagetable(address);
if (error_code & X86_PF_RMP)
sev_dump_rmpentry(pfn);
instead of passing around this SEV-specific arg in generic x86 fault code.
The change to return the pfn from dump_pagetable() should be a pre-patch ofc.
Thx.
