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
Nicholas Piggin (9):
powerpc/powernv: Remove real mode access limit for early allocations
powerpc/pseries: radix is not subject to RMA limit, remove it
powerpc/64: rtas avoid accessing paca in 32-bit mode
powerpc/pseries: lift RTAS limit for radix
powerpc/pseries: lift RTAS limit for hash
powerpc/64s: Relax PACA address limitations
powerpc/64s: do not allocate lppaca if we are not virtualized
powerpc/64: Use array of paca pointers and allocate pacas individually
powerpc/64s: Use array of lppaca pointers and allocate lppacas
individually
