[PATCH 1/2] virtio-balloon: initialize all vq callbacks
...k pointers would not actually be
dereferenced; however, the uninitialized callbacks elements would still
be read in vp_find_vqs_msix() and used to calculate the number of MSI-X
vectors required.

[PATCH] virtio-balloon: request nvqs based on features
...store the logic that chose nvqs conditionally based on enabled
features, which was removed as part of the aforementioned commit.
This is slightly more complex than just incrementing a counter of the
number of VQs, since the queue for a given feature is assigned a fixed
index.

[PATCH] win32: only use dllexport when building DLL
If building a static library, marking symbols as dllexport causes them
to be exported from the final executable. For example, run
objdump -x opus_demo.exe on a --disabled-shared build and look for the
export table; there should not be one in a normal Win32 .exe file, but
when linking static libopus, the exe exports all of the opus_* public
functions.
Use the libtool-defined DLL_EXPORT flag to

Regression with "arm64: KVM: Skip MMIO insn after emulation" on 4.4 stable
Hello,
In my testing of crosvm[1] with Linux 4.4.175, I am observing failures
on a 'kevin' Chromebook (RK3399) device - the guest kernel does not
even get to the point of printing its first messages, and the host
seems to be spinning at 100% CPU in KVM_RUN.
I narrowed this down to the 4.4 stable backport of "arm64: KVM: Skip
MMIO insn after emulation" - with this patch
