Subject[RFC 3/3] x86, mirror: x86 enabling - find mirrored memory ranges and tell memblock
Can't post this part yet because it uses things in an upcoming[*] ACPI, UEFI, or some
other four-letter-ending-in-I standard. So just imagine a call someplace early
in startup that reads information about mirrored address ranges and does:

+ for (...) {
+ start = ...;
+ size = ...;
+ if (it looks mirrored)
+ memblock_mark_mirror(start, size);
+ }

Whole patch is pretty tiny:

3 files changed, 19 insertions(+)

How much damage could I possibly do in just 19 lines?

[*] very soon, I'm told
