9952e807fd vhost-user+postcopy: Use qemu_set_nonblock
Use qemu_set_nonblock rather than a simple fcntl; cleaner
and I have no reason to change other flags.

6f80e6170e virtio: support setting memory region based host notifier
This patch introduces the support for setting memory region
based host notifiers for virtio device. This is helpful when
using a hardware accelerator for a virtio device, because
hardware heavily depends on the notification, this will allow
the guest driver in the VM to notify the hardware directly.

703878e2e0 vhost-user: add Net prefix to internal state structure
We are going to introduce a shared vhost user state which
will be named as 'VhostUserState'. So add 'Net' prefix to
the existing internal state structure in the vhost-user

9882d3ef3c update-linux-headers.sh: unistd.h, kvm consistency
Rework the update script slightly, add the unistd.h header and its
dependencies on all architectures.

This also removes the IA64 and MIPS from a KVM blacklist:
Linux dropped IA64, and there was never a reason to
exclude MIPS from kvm specifically - it was
excluded due to dependency of its unistd.h on sgidefs.h,
which we also import.

It turns out (as will be clear from follow-up patches)
we do not really need any kvm para macros host side

unconditionally whether we run on kvm or we don't.

Import the x86 asm/kvm_para.h into standard-headers,

ffcbbe722f vhost: add trace for IOTLB miss
Add some trace points for IOTLB translation for vhost. After vhost-user
is setup, the only IO path that QEMU will participate should be the
IOMMU translation, so it'll be good we can track this with explicit
timestamps when needed to see how long time we take to do the
translation, and whether there's anything stuck inside.  It might be
useful for triaging vhost-user problems.

"Some AMD processors only support a non-architectural means of enabling
speculative store bypass disable (SSBD).  To allow a simplified view of
this to a guest, an architectural definition has been created through a new
CPUID bit, 0x80000008_EBX[25], and a new MSR, 0xc001011f.  With this, a
hypervisor can virtualize the existence of this definition and provide an
architectural method for using SSBD to a guest.

Add the new CPUID feature, the new MSR and update the existing SSBD
support to use this MSR when present." (from x86/speculation: Add virtualized
speculative store bypass disable support in Linux).

aec0d0e118 qemu-options: Allow -no-user-config again
After 1217d6ca2b we error out
explicitly if an unknown -option was passed on the command line.
However, we are doing two pass command line option parsing. In
the first pass we just look for -no-user-config or -nodefconfig
being present which determines whether we load user config or
not. Then in the second pass we finally parse everything else
throwing an error if an unsupported -option was found. Problem is
that in the second pass -no-user-config and -nodefconfig are not
handled explicitly which makes us throw the unsupported option
error.

7647d5c6b5 tests: fix tpm-crb tpm-tis tests race
No need to close the TPM data socket on the emulator end, qemu will
close it after a SHUTDOWN. This avoids a race between close() and
read() in the TPM data thread.

4885b0caf6 qemu-img-cmds.hx: add passive-aggressive note
I'm kidding. It's very easy to forget there are per-command sections
in the texi, and insane that we don't autogenerate those, too.

Until then, leave a little post-it note in this .hx file until I
find a way to delete it.

9775fcdb11 qemu-img: Make documentation between .texi and .hx consistent
These are also different and out of order for whatever reason.
I'd like to automate this in the future, but for now let's put
on the band-aid.

In the case of resize, there were options missing from all
three docstrings; the new string is based on the code.

corresponding PRIx64 format, not HWADDR_PRIx which is intended for use
with the 'hwaddr' type.
