Avi reported [1] that target-xtensa incorrectly supply virtual addresses to tb_invalidate_phys_page_range. Currently there's no way to invalidate all cached TBs at the given virtual address in softmmu mode. As a shortcut solution I translate virtual address to physical address using guest TLB and reuse most of breakpoint_invalidate() code to invalidate TB at that physical address.
This series is extracted from my recent xtensa pull request, build of usermode targets is fixed.
