would be good to send these out now as there are some other patch sets
on the mailing list that are getting ready to go.
As far as the actual patches, there's:
* A set that cleans up our FS dirty-mode handling.
* Support for writing MISA.
* The removal of Michael as a maintainer.
* A fix to {m,s}counteren handling.
* A fix to make sure the kernel's start address is computed correctly on

This makes my "RISC-V Patches for 3.2, Part 3" pull request defunct, as

I've tested this using a Fedora boot on the latest Linux. This patch
set does not include Bastian's decodetree patches because there were

The current check to test if usbfs support should be compiled or not
solely relies on the presence of <linux/usbdevice_fs.h>, without
actually checking that all definition used by Qemu are provided by
this header file.
With sufficiently old kernel headers, <linux/usbdevice_fs.h> may be
present, but some of the definitions needed by Qemu may not be
available.
This commit improves the check by building a small program that
actually tests whether the necessary definitions are available.
In addition, it fixes a bug where have_usbfs was set to "yes"
regardless of the result of the test.

The sun4uv_init() function expects vga_interface_type to be either
VGA_STD or VGA_NONE and sets up a stdvga device or no vga card
accordingly.
However, the code in vl.c prefers the Cirrus VGA card to stdvga if
it is available and the user and the machine did not specify anything
else.
So far this has not been a problem, since the Cirrus VGA was not linked
into the sparc64 target. But with the upcoming Kconfig build system,
all theoretically possible PCI cards will be enabled by default, so the
Cirrus VGA card might become available on the sparc64 target, too. vl.c
then picks the wrong card, causing sun4uv_init() to abort.
Thus let's make it explicit that we always want stdvga for sparc64 and
so set default_display = "std" for these machines.

The lock usage was described with its introduction in commit
9005b2a758. It was necessary because PTY
write() shares more state than GIOChannel with other
operations.
This made char-pty a bit different from other chardev, that only lock
around the write operation. This was apparent in commit
7b3621f47a, which introduced an idle
source to avoid the lock.
By removing the PTY chardev state sharing on write() with previous
patch, we can remove the lock and the idle source.

This doesn't help much compared to the 1 second poll PTY

Commit caa1ee43 "vhost-user-blk: add discard/write zeroes features

the size of the config space and breaks migration from QEMU 3.1
and older:
qemu-system-ppc64: get_pci_config_device: Bad config data: i=0x10 read: 41 device: 1 cmask: ff wmask: 80 w1cmask:0
qemu-system-ppc64: Failed to load PCIDevice:config

qemu-system-ppc64: load of migration failed: Invalid argument
Since virtio-blk doesn't support the "discard" and "write zeroes"
features, it shouldn't even expose the associated fields in the
config space actually. Just include all fields up to num_queues to
match QEMU 3.1 and older.

QEMU wraps the socket functions in os-win32.h, but in commit
a9d8b3ec43, the header inclusion was dropped,
breaking libslirp on Windows.
There are already a few socket functions that are wrapped in libslirp,
with "slirp_" prefix, but many of them are missing, and we are going
to wrap the missing functions in a second patch.
Using "slirp_" prefix avoids the conflict with socket function #define
wrappers in QEMU os-win32.h, but they are quite intrusive. In the end,
the functions should behave the same as original one, but with errno
being set. To avoid the churn, and potential confusion, remove the
"slirp_" prefix. A series of #undef is necessary until libslirp is
made standalone to prevent the #define conflict with QEMU.
