[PATCH] x86_64: Fix memory hotadd heuristics
This fixes some boot failures on Dell and Unisys systems with memory
hotadd added.
- Set hotadd_percent to 0 by default. This means anybody using hotadd
memory needs to specify the value on the command line. That's
because there are lots of Intel boxes which have a bogus hotplug area
in their SRAT and they would waste a lot of memory before.
- Fix calculation of how much memory to use when the hotplug area
exceeds hotadd_percent
- Fix fallback when the
- Fix fallback if memory hotadd is not compiled in.
