Make vhost-user-blk backwards compatible when migrating from older VMs
running with modern features turned off, the same way it was done for
virtio-blk in 20764be0421c ("virtio-blk: set config size depending on the
features enabled")
It's currently impossible to migrate from an older VM with
This way we can reuse it for other virtio-blk devices, e.g
vhost-user-blk, which currently does not control its config space size
dynamically.

target/riscv: Make translator stop before the end of a page (2022-09-06
08:04:26 +0100
The base qemu_ram_addr_from_host function is already in
softmmu/physmem.c; move the nofail version to be adjacent.

Currently it's possible to execute pages that do not have PAGE_EXEC
if there is an existing translation block. Fix by invalidating TBs
that touch the affected pages.

From: Ilya Leoshkevich
Right now translator stops right *after* the end of a page, which
breaks reporting of fault locations when the last instruction of a
multi-insn translation block crosses a page boundary.

load_image_to_fw_cfg() is duplicated by both arm and loongarch. The same
function will be required by riscv too. So, it's time to refactor and
move this function to a common path.

Use the pc coming from db->pc_first rather than the TB.
Use the cached host_addr rather than re-computing for the
first page. We still need a separate lookup for the second
page because it won't be computed for DisasContextBase until
the translator actually performs a read from the page.
Wrap the bare TranslationBlock pointer into a structure.

The goal here is to reduce the amount of code generation when the
guest kernel enables address space randomization. This requires
extensive changes to each target, so opt-in with TARGET_TB_PCREL.
This is split out of v3, which also contained target/arm
