[ 5.525861] ERST: Can not request iomem region <0x c7eff000-0x c7f00000> for ERST.

This needs to have leading zeroes. Make it so.

Why does it need leading zeros?

While looking at this, I noticed that we seem to be using varying field
widths in our APEI code:
- einj.c has two instances using %#010llx.
- apei-base.c uses widths of 10 (4 bytes) and 6 (2 bytes).

Not sure if these are intentional and those fields truly aren't 64-bit
(as suggested by the usage of long long int).

I suggest using "0x%llx" everywhere unless there's a
compelling reason like columnar alignment for them.

I think that might be better. I see that these changes were done in commit 46b91e37. Copying Bjorn Helgaas.

Oh, I've hardly scratched the surface w.r.t APEI. I think I'll let the experts comment on this :)
