ndb - bug#34378
Using more than 16g can cause record-pool ptr.i values to overflow
Fix by splitting memory into 2 zones, lo(16g)/hi(rest)
When record pools only use zone_lo, and datamemory, buffers etc...can use any
storage/ndb/src/kernel/blocks/lgman.cpp:
adopt to changed interface for Ndbd_mem_manager
storage/ndb/src/kernel/vm/Pool.cpp:
Always use ZONE_LO for record pools
as they use ptr.i == 19 bit page id + 13 bit page index
storage/ndb/src/kernel/vm/ndbd_malloc_impl.cpp:
Add zones to Ndbd_mem_manager
ZONE_LO = lower 16g
ZONE_HI = rest
storage/ndb/src/kernel/vm/ndbd_malloc_impl.hpp:
Add zones to Ndbd_mem_manager
ZONE_LO = lower 16g
ZONE_HI = rest
