block/backup: fix fleecing scheme: use serialized writes
Fleecing scheme works as follows: we want a kind of temporary snapshot
of active drive A. We create temporary image B, with B->backing = A.
Then we start backup(sync=none) from A to B. From this point, B reads
as point-in-time snapshot of A (A continues to be active drive,
accepting guest IO).
This scheme needs some additional synchronization between reads from B
and backup COW operations, otherwise, the following situation is
theoretically possible:
(assume B is qcow2, client is NBD client, reading from B)
1. client starts reading and take qcow2 mutex in qcow2_co_preadv, and
goes up to l2 table loading (assume cache miss)
2) guest write => backup COW => qcow2 write =>
try to take qcow2 mutex => waiting
3. l2 table loaded, we see that cluster is UNALLOCATED, go to
"case QCOW2_CLUSTER_UNALLOCATED" and unlock mutex before
bdrv_co_preadv(bs->backing, ...)
4) aha, mutex unlocked, backup COW continues, and we finally finish
guest write and change cluster in our active disk A
5. actually, do bdrv_co_preadv(bs->backing, ...) and read
_new updated_ data.
To avoid this, let's make backup writes serializing, to not intersect
with reads from B.
Note: we expand range of handled cases from (sync=none and
B->backing = A) to just (A in backing chain of B), to finally allow
safe reading from B during backup for all cases when A in backing chain
of B, i.e. B formally looks like point-in-time snapshot of A.

Here two things are fixed:
1. Architecture

2. Wait for serializing requests on write path independently of

block: Poll after drain on attaching a node
Commit
dcf94a23b1 ('block: Don't poll in parent drain callbacks')
removed polling in bdrv_child_cb_drained_begin() on the grounds that the
original bdrv_drain() already will poll and BdrvChildRole.drained_begin
calls must not cause graph changes (and therefore must not call
aio_poll() or the recursion through the graph will break.
This reasoning is correct for calls through bdrv_do_drained_begin().
However, BdrvChildRole.drained_begin is also called when a node that is
already in a drained section (i.e. bdrv_do_drained_begin() has already
returned and therefore can't poll any more) is attached to a new parent.
In this case, we must explicitly poll to have all requests completed
before the drained new child can be attached to the parent.
In bdrv_replace_child_noperm(), we know that we're not inside the
recursion of bdrv_do_drained_begin() because graph changes are not
allowed there, and bdrv_replace_child_noperm() is a graph change. The
call of BdrvChildRole.drained_begin() must therefore be followed by a
BDRV_POLL_WHILE() that waits for the completion of requests.

DeviceClass::reset models a "cold power-on" reset which can
also be used to powercycle a device; but there is no "hot reset"

The OMAP MMC Power-Up Control bit is not designed to powercycle
a card, but to disable it without powering it off (pseudo-reset):
Multimedia Card (MMC/SD/SDIO) Interface [SPRU765A]
MMC_CON[11] Power-Up Control (POW)
This bit must be set to 1 before any valid transaction to either
MMC/SD or SPI memory cards.
When 1, the card is considered powered-up and the controller core
is enabled.
When 0, the card is considered powered-down (system dependent),
and the controller core logic is in pseudo-reset state. This is,
the MMC_STAT flags and the FIFO pointers are reset, any access to
MMC_DATA[DATA] has no effect, a write into the MMC.CMD register
is ignored, and a setting of MMC_SPI[STR] to 1 is ignored.

hw/timer/cmsdk-apb-timer: run or stop timer on writes to RELOAD and VALUE
If the CMSDK APB timer is set up with a zero RELOAD value
then it will count down to zero, fire once and then stay
at zero. From the point of view of the ptimer system, the
timer is disabled; but the enable bit in the CTRL register
is still set and if the guest subsequently writes to the
RELOAD or VALUE registers this should cause the timer to
start counting down again.
Add code to the write paths for RELOAD and VALUE so that
we correctly restart the timer in this situation.
Conversely, if the new RELOAD and VALUE are both zero,
we should stop the ptimer.

checkpatch: handle token pasting better
The mechanism to find possible type tokens can sometimes be confused and go into an
infinite loop. This happens for example in QEMU for a line that looks like
uint## BITS ##_t S = _S, T = _T; \
uint## BITS ##_t as, at, xs, xt, xd; \
Because the token pasting operator does not have a space before _t, it does not
match $notPermitted. However, (?x) is turned on in the regular expression for
modifiers, and thus ##_t matches the empty string. As a result, annotate_values
goes in an infinite loop.
The solution is simply to remove token pasting operators from the string before
looking for modifiers. In the example above, the string uintBITS_t will be
evaluated as a candidate modifier. This is not optimal, but it works as long
as people do not write things like a##s##m, and it fits nicely into sub
possible.
For a similar reason, \# should be rejected always, even if it is not
at end of line or followed by whitespace.
The same patch was sent to the Linux kernel mailing list.

pr-helper: avoid error on PR IN command with zero request size
After reading a PR IN command with zero request size in prh_read_request,
the resp->result field will be uninitialized and the resp.sz field will
be also uninitialized when returning to prh_co_entry.
If resp->result == GOOD (from a previous successful reply or just luck),
then the assert in prh_write_response might not be triggered and
uninitialized response will be sent.
The fix is to remove the whole handling of sz == 0 in prh_co_entry.
Those errors apply only to PR OUT commands and it's perfectly okay to
catch them later in do_pr_out and multipath_pr_out; the check for
too-short parameters in fact doesn't apply in the easy SG_IO case, as
it can be left to the target firmware even.
The result is that prh_read_request does not fail requests anymore and

RISC-V: SoCify SiFive boards and connect GEM
This series has three tasks:
1. To convert the SiFive U and E machines into SoCs and boards
2. To connect the Cadence GEM device to the SiFive U board
3. Fix some device tree problems with the SiFive U board
After this series the SiFive E and U boards have their SoCs split into
seperate QEMU objects, which can be used on future boards if desired.
The RISC-V Virt and Spike boards have not been converted. They haven't
been converted as they aren't physical boards, so it doesn't make a
whole lot of sense to split them into an SoC and board. The only
disadvantage with this is that they now differ to the SiFive boards.
This series also connect the Cadence GEM device to the SiFive U board.
There are some interrupt line changes requried before this is possible.

docker: add linux-user powered cross builder for QEMU
We can't use cross compilers in the current Debian stable and Debian
sid is sketchy as hell. So for powerpc fall back to dog-fooding our
own linux-user to do the build.
As we can only build the base image with a suitably configured
source tree we fall back to checking for its existence when we can't
build it from scratch. However this does mean you don't have to keep
a static powerpc-linux-user in your active configuration just to
update the cross build image.
