This patch series implements vhost-pci, which is a point-to-point based
inter-vm communication solution. The QEMU side implementation includes the
vhost-user extension, vhost-pci device emulation and management, and inter-VM
notification.
v1->v2 changes:
1) inter-VM notification support;
2) vhost-
An example of the QEMU command to create a vhost-pci-slave is:
-chardev socket,id=slave1,server,wait=off,path=${PATH_SLAVE1}
-vhost-pci-slave socket,chardev=slave1
The master can connect to the slave as usual:
-chardev socket,id=sock2,path=${PATH_SLAVE1}
-netdev type=vhost-user,id=net2,chardev=soc

Per default any SCSI commands are sent with an infinite timeout,

We likely do not want to carry these legacy -drive options along forever.
Let's emit a deprecation warning for the -drive options that have a
replacement with the -device option, so that the (hopefully few) remaining

The attached simple program, compiled as a library, loaded by LD_PRELOAD
before starting QEMU, avoids the problem by faking success of
libusb_set_configuration(), as a workaround.

No; recent processors don't have A20 at all.

The strict td link limit added by commit "05f43d4 xhci: limit the
number of link trbs we are willing to process" causes problems with
Windows guests. Let's raise the limit.
This change is analogous to:

The preferred way of adding USB devices is via "-device" and
"device_add" nowadays, so let's start to get rid of "-usbdevice"
and "usb_add" in the documentation. While we're at it, also
add the new USB devices there which have been added to QEMU
during the last years, and get ri

Fix the ssetmask() system call by removing the invocation of sigorset().
The ssetmask() system call should replace the old signal mask
with the new and return the old mask. It shouldn't combine
the old and the new mask with sigorset(). Fetching the old
mask for sigorset() is also no longer needed.
Add two inline functions that work with the signal set of the target.
target_sigdelset() removes a signal from target_sigset_t.
target_sigorset() creates a union of two target_sigset_t.
These functions will be used for introducing support for tracking the
target signal set. Functions for emptying
Add support for tracking the larger target signal mask in system calls
sigprocmask()/rt_sigprocmask(), sigsuspend()/rt_sigsuspend(),
sgetmask()/ssetmask() and in functions do_sigreturn(), do_rt_sigreturn(),
handle_pending_signal(), process_pending_signals().
Add a new function do_target_sigprocmask
Fix copying between the host and target signal sets for the case when the
target set is larger than the host set.
sigismember() returns 1 if the specified signal number is a member of
the specified signal set, but it can also return -1 if an error occurs
(e.g. an out of range signal number is spec
This patch improves the consistentcy of the output from print_siginfo()
by removing spaces around the equal sign of si_pid, si_uid, si_timer1,
si_timer2, si_band, si_fd, si_addr, si_status and si_sigval. This way
they match si_signo and ci_code. Host strace was used as a reference
for this chage.
Change the type of the first argument of rt_sigqueinfo() from int to pid_t
in the syscall declaration to match specifications of the system call.
Proper spacing is added to satisfy checkpatch.pl.
