[PATCH 0/6] virtio: refactor host notifiers
The benifit is we don't use event_notifier_set_handler even in non-dataplane
now, which in turn makes virtio-blk and virtio-scsi follow block layer aio
context semantics. Specifically, I/O requests must come

The SCU is a collection of chip-level control registers that manage the
various functions supported by ASPEED SoCs. Typically the bits control
interactions with clocks, external hardware or reset behaviour, and we
can largly take a hands-off approach to reads and writes.

By specifying the silicon revision we select the appropriate reset
values for the SoC.
Additionally, expose hardware strapping properties aliasing those

Hi all,
These are three patches implementing minimal functionality for the ASPEED System
Control Unit device and integrating it into the AST2400 SoC model/palmetto-bmc

This allows us to enforce 16 and 64-byte alignment
without any extra overhead.

The NBD protocol doesn't have any notion of sectors, so it is
a fairly easy convertion to use byte-based read and write.

With these two patches, I'm finally able to run:
./qemu-nbd -f raw -x foo file
./qemu-io -f raw -t none nbd://localhost:10809/foo
and get true byte-based access over the wire for operations such
as 'r 1 1' or 'w 1 1', rather than RMW sector-aligned access.
Depends on these series:

Instead of using -1 as end of chain, use 0, and link through the 0
entry as a fully circular double-linked list.

Since the raw format driver is just passing things through, we can
do byte-based read and write if the underlying protocol does
likewise.
There's one tricky part - if we probed the image format, we document
that we restrict operations on the initial sector. Rather than
trying to handle a read-mod

Rather than rely on recursion during the middle of register allocation,

For an x86_64 host, with sufficient registers, this results in identical

Reduce the size of other bitfields to make room.
This reduces the cache footprint of compilation.

While we can store constants via constrants on INDEX_op_st_i32 et al,
we weren't able to spill constants to backing store.
Add a new backend interface, tcg_out_sti, which may store the constant

I was unhappy about the complexity of the second try.
Better to convert to normal temps, allowing in rare
