Subject: efi_call on SGI

Btw,

while we're at it, I see uv_bios_call is sometimes done with preemption
disabled around it and sometimes it is not (at least I don't see it)...

In any case, if SGI uses the EFI pagetable now too, you probably would
want to do the efi calls like the rest of x86 does them - see the 64-bit
version of efi_call_virt() in arch/x86/include/asm/efi.h for an example
what I mean.

Now, you could either copy that macro or you could accomodate it to
serve everyone's needs - depends on what you'd prefer.

I'm just saying - I had stumbled across this while the debugging session
was going on and wanted to point that out but it wasn't too important at
the time so...

HTH.
