Revert "memory: Optimize replay of guest mapping"
This reverts commit 6da24341866fa940fd7d575788a2319514941c77
("memory: Optimize replay of guest mapping").
This change breaks the mps3-an547 board under TCG (and
probably other TCG boards using an IOMMU), which now
assert:
$ ./build/x86/qemu-system-arm --machine mps3-an547 -serial stdio
-kernel /tmp/an547-mwe/build/test.elf
qemu-system-arm: ../../softmmu/memory.c:1903:
memory_region_register_iommu_notifier: Assertion `n->end <=
memory_region_size(mr)' failed.
This is because tcg_register_iommu_notifier() registers
an IOMMU notifier which covers the entire address space,
so the assertion added in this commit is not correct.
For the 8.0 release, just revert this commit as it is
only an optimization.
