Using phys_page_find to translate an AddressSpace to a MemoryRegionSection is unwieldy. It requires to pass the page index rather than the address, and later memory_region_section_addr has to be called. Replace memory_region_section_addr with a function that does all of it: call phys_page_find, compute the offset within the region, and check how big the current mapping is. This way, a large flat region can be written with a single lookup rather than a page at a time. address_space_translate will also provide a single point where IOMMU forwarding is implemented.

It is never used, the IOTLB always goes through io_mem_notdirty. In fact in softmmu_template.h, if it were, QEMU would crash just below the tests, as soon as io_mem_read/write dispatches to error_mem_read/write.

The radix tree is statically sized to fit TARGET_PHYS_ADDR_SPACE_BITS. If a larger memory region is registered, it will overflow. Fix by limiting any section in the radix tree to the supported size. This problem was not observed earlier since artificial regions (containers and aliases) are eliminated by the memory core, leaving only device regions which have reasonable sizes. An IOMMU however cannot be eliminated by the memory core, and may have an artificial size.

We switched from qemu_memalign to mmap() but then we don't modify qemu_vfree() to do a munmap() over free(). Which we cannot do because qemu_vfree() frees memory allocated by qemu_{mem,block}align. Introduce a new function that does the munmap(), luckily the size is available in the RAMBlock.

Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

Fix some of the nasty TCG race conditions and crashes by implementing cpu_exit() as setting a flag which is checked at the start of each TB. This avoids crashes if a thread or signal handler calls cpu_exit() while the execution thread is itself modifying the TB graph (which may happen in system emulation mode as well as in linux-user mode with a multithreaded guest binary). This fixes the crashes seen in LP:668799; however there are another class of crashes described in LP:1098729 which stem from the fact that in linux-user with a multithreaded guest all threads will use and modify the same global TCG date structures (including the generated code buffer) without any kind of locking. This means that multithreaded guest binaries are still in the "unsupported" category.
