Cover letter [PATCH 0/9] modernize early memory allocation limits and
This series improves (mostly relaxes) limits on early memory allocations for stacks, pacas, etc. on 64s.
It also avoids allocating lppacas for bare metal, and it changes allocation of paca and lppaca from single big arrays to inividual allocations.
The main goal of this is toward allocating these basic structures per-node. We're not there yet, but closer.
Thanks,
Nick
