Most notabbly, there now is an upstream workaround for the "Windows
PCI Label bug" [0] and the revert of QEMU commit 44d975ef34 ("x86:
acpi: workaround Windows not handling name references in Package
properly") can be dropped.
Pick up some other fixes already merged in current master, for
emulation as well as x86(_64) KVM, some PCI/USB fixes and a pair of
regression fixes for the net subsystem.

The end vector calculation has a bug that results in polling fewer
|
|
than required vectors when reading at a non-zero offset in PBA memory.
|
|
|
|
Fixes: bbef882cc193 ("msi: add API to get notified about pending bit poll")
