[Qemu-devel] [PATCH 0/8] Optimize address_space_read/write/map

[Paolo Bonzini <pbonzini@redhat.com>]

Avoid unnecessary object_ref/unref and rcu_read_lock/unlock.
Inline constant-length reads to avoid variable-sized memcpy.

Paolo Bonzini (8):
  exec: always call qemu_get_ram_ptr within rcu_read_lock
  exec: make qemu_ram_ptr_length more similar to qemu_get_ram_ptr
  memory: reorder MemoryRegion fields
  memory: avoid unnecessary object_ref/unref
  memory: split address_space_read and address_space_write
  memory: extract first iteration of address_space_read and
    address_space_write
  memory: inline a few small accessors
  memory: try to inline constant-length reads
