The current implementation of hot-unplug handler is abrupt. Any pci
operation will be just rejected if pci device is unconfigured. Thus a
pci device can not be reset or destroyed in a right, smooth and safe
way.
Improve this as follows:
- Notify the guest via a HP_EVENT_DECONFIGURE_REQUEST(0x303) event in
the unplug handler, giving it a chance to deconfigure the device via
sclp and allowing us to continue hot-unplug afterwards.
- Set up a timer that will generate the HP_EVENT_CONFIGURE_TO_STBRES
(0x304) event as before if the guest did not react after an adequate
time.

To support definitions of s390 pci attributes in Qemu cmdline, we have
to make current S390PCIBusDevice struct inherit DeviceState and add
three properties for it. Currently we only support definitions of uid
and fid.
'uid' is optionally defined by users, identifies a zpci device and
must be defined with a 16-bit and non-zero unique value.
'fid' ranges from 0x0 to 0xFFFFFFFF. For fid property, we introduce a
new PropertyInfo by the name of s390_pci_fid_propinfo with our special
setter and getter. As 'fid' is optional, introduce 'fid_defined' to
track whether the user specified a fid.
'target' field is to direct qemu to find the corresponding generic PCI
device. It is equal to the 'id' value of one of generic pci devices.
If the user doesn't specify 'id' parameter for a generic pci device,
its 'id' value will be generated automatically and use this value as
'target' to create an associated zpci device.
If the user did not specify 'uid' or 'fid', values are generated
automatically. 'target' is required.
In addition, if a pci device has no associated zpci device, the code
will generate a zpci device automatically for it.

In user-mode emulation Translation Block can consist of 2 guest pages.
In that case QEMU also mprotects 2 host pages that are dedicated for
guest memory, containing instructions. QEMU detects self-modifying code
with SEGFAULT signal processing.
In case if instruction in 1st page is modifying memory of 2nd
page (or vice versa) QEMU will mark 2nd page with PAGE_WRITE,
invalidate TB, generate new TB contatining 1 guest instruction and
exit to CPU loop. QEMU won't call mprotect, and new TB will cause
same SEGFAULT. Page will have both PAGE_WRITE_ORG and PAGE_WRITE
flags, so QEMU will handle the signal as guest binary problem,
and exit with guest SEGFAULT.
Solution is to do following: In case if current TB was invalidated
continue to invalidate TBs from remaining guest pages and mark pages
as PAGE_WRITE. After that disable host page protection with mprotect.
If current tb was invalidated longjmp to main loop. That is more
efficient, since we won't get SEGFAULT when executing new TB.

As it currently stands, QEMU does not properly handle self-modifying code
when the write is unaligned and crosses a page boundary. The procedure
for handling a write to the current translation block is to write-protect
the current translation block, catch the write, split up the translation
block into the current instruction (which remains write-protected so that
the current instruction is not modified) and the remaining instructions
in the translation block, and then restore the CPU state to before the
write occurred so the write will be retried and successfully executed.
However, since unaligned writes across pages are split into one-byte
writes for simplicity, writes to the second page (which is not the
current TB) may succeed before a write to the current TB is attempted,
and since these writes are not invalidated before resuming state after
splitting the TB, these writes will be performed a second time, thus
corrupting the second page. Credit goes to Patrick Hulin for
discovering this.
In recent 64-bit versions of Windows running in emulated mode, this
results in either being very unstable (a BSOD after a couple minutes of
uptime), or being entirely unable to boot. Windows performs one or more
8-byte unaligned self-modifying writes (xors) which intersect the end
of the current TB and the beginning of the next TB, which runs into the
aforementioned issue. This commit fixes that issue by making the
unaligned write loop perform the writes in forwards order, instead of
reverse order. This way, QEMU immediately tries to write to the current
TB, and splits the TB before any write to the second page is executed.
The write then proceeds as intended. With this patch applied, I am able
to boot and use Windows 7 64-bit and Windows 10 64-bit in QEMU without
KVM.
Per Richard Henderson's input, this patch also ensures the second page
is in the TLB before executing the write loop, to ensure the second
page is mapped.

to 3, but will warn only about "x86_64-cpu.vendor" being ignored.
$ ./x86_64-softmmu/qemu-system-x86_64 \
-global x86_64-cpu.vendor=x \
-global x86_64-cpu.level=3
qemu-system-x86_64: Warning: global x86_64-cpu.vendor=x ignored: Property '.vendor' doesn't take value 'x'
Fix this by not returning from qdev_prop_set_globals_for_type()
on the first error.
