[0/4] ia64: switch to NO_BOOTMEM

Message

Hi,

These patches convert ia64 to use NO_BOOTMEM.

The first two patches are cleanups, the third patches reduces usage of
'struct bootmem_data' for easier transition and the forth patch actually
replaces bootmem with memblock + nobootmem.

I've tested the sim_defconfig with the ski simulator and build tested other
defconfigs.

Mike Rapoport (4):
  ia64: contig/paging_init: reduce code duplication
  ia64: remove unused num_dma_physpages member from 'struct early_node_data'
  ia64: use mem_data to detect nodes' minimal and maximal PFNs
  ia64: switch to NO_BOOTMEM

Boots OK on my real ia64 system.

Unless somebody else sees an issue I'll push to Linus nest merge window.
