df3ac6da47 target/riscv: Fix itrigger when icount is used 
When I boot a ubuntu image, QEMU output a "Bad icount read" message and exit.
The reason is that when execute helper_mret or helper_sret, it will
cause a call to icount_get_raw_locked (), which needs set can_do_io flag
on cpustate.

Thus we setting this flag when execute these two instructions.

There are bogus 0 entries added at the end, of which one is of
insufficient length. This happens because only 15 of
fdt_event_ctr_map[]'s 20 elements are populated & qemu_fdt_setprop() is
called using the size of the array.

378e43fa72 target/riscv: refactor Zicond support 
After the original Zicond support was stuck/fell through the cracks on
the mailing list at v3 (and a different implementation was merged in
the meanwhile), we need to refactor Zicond to prepare it to be reused
by XVentanaCondOps.

This commit lifts the common logic out into gen_czero and uses this
via gen_logic and 2 helper functions (effectively partial closures).

Fixes this commit, clearly a bad merge after a rebase or similar, it
should have been its own case since that point.

3cba22c9ad migration: Fix block_bitmap_mapping migration 
It is valid that params->has_block_bitmap_mapping is true and
params->block_bitmap_mapping is NULL.  So we can't use the trick of
having a single function.

Move to two functions one for each value and the tests are fixed.

86dcb6ab9b qga: Fix suspend on Linux guests without systemd 
Allow the Linux guest agent to attempt each of the suspend methods
(systemctl, pm-* and writing to /sys) in turn.

Prior to this guests without systemd failed to suspend due to
`guest_suspend` returning early regardless of the return value of
`systemd_supports_mode`.

8cc28cb16e qga/commands-win32.c: Drop the check for _WIN32_WINNT >= 0x0601 
All current versions of glib require _WIN32_WINNT set to 0x0601
or higher already, and we also use this value as a minimum in our
osdep.h header file, so there is no way to still compile this code
with an older version of the Windows ABI. Thus we can drop this
check now.

810f677ab8 qga: Add merged variant to GuestExecCaptureOutputMode 
Currently, any captured output (via `capture-output`) is segregated into
separate GuestExecStatus fields (`out-data` and `err-data`). This means
that downstream consumers have no way to reassemble the captured data
back into the original stream.

This is relevant for chatty and semi-interactive (ie. read only) CLI
tools.  Such tools may deliberately interleave stdout and stderr for
visual effect. If segregated, the output becomes harder to visually
understand.

This commit adds a new enum variant to the GuestExecCaptureOutputMode
qapi to merge the output streams such that consumers can have a pristine
view of the original command output.

9c5ccc52ab qga: Refactor guest-exec capture-output to take enum 
Previously capture-output was an optional boolean flag that either
captured all output or captured none. While this is OK in most cases, it
lacks flexibility for more advanced capture cases, such as wanting to
only capture stdout.

This commits refactors guest-exec qapi to take an enum for capture mode
instead while preserving backwards compatibility.

de79b52604 block/export: call blk_set_dev_ops(blk, NULL, NULL) 
Most export types install BlockDeviceOps pointers. It is easy to forget
to remove them because that happens automatically via the "drive" qdev
property in hw/ but not block/export/.

Put blk_set_dev_ops(blk, NULL, NULL) calls in the core export.c code so
the export types don't need to remember.

This fixes the nbd and vhost-user-blk export types.

Fixes: fd6afc501a ("nbd/server: Use drained block ops to quiesce the server")
Fixes: ca858a5fe9 ("vhost-user-blk-server: notify client about disk resize")
