[Qemu-devel] [PATCH v2 0/7] memory: Clean up MemoryRegion.ram_addr and optimize address_space_translate

[Fam Zheng]

v2: In the optimization patch, factor out section_covers_addr() and use it.
    [Paolo, Peter]
    Check "ram_block == NULL" in patch 3. [Gonglei]
    Add Gonglei's rev-by in patches 1, 2, 4 and 5.

The first four patches drop ram_addr from MemoryRegion on top of Gonglei's
optimization.

The next patch simplifies qemu_ram_free a bit by passing the RAMBlock pointer.

The last patch speeds up address_space_translate with a cache pointer inside
the AddressSpaceDispatch.

Fam Zheng (7):
  exec: Return RAMBlock pointer from allocating functions
  memory: Move assignment to ram_block to memory_region_init_*
  memory: Implement memory_region_get_ram_addr with mr->ram_block
  memory: Drop MemoryRegion.ram_addr
  exec: Pass RAMBlock pointer to qemu_ram_free
  exec: Factor out section_covers_addr
  exec: Introduce AddressSpaceDispatch.mru_section
