[PATCH 0/3] OvmfPkg/QemuVideoDxe/VbeShim: handle PAM1 register on Q35 correctly

[Laszlo Ersek <lersek@redhat.com>]

Repo:   https://github.com/lersek/edk2.git
Branch: vbe_shim_q35_pam

Fix the long-standing OVMF/Q35 bug recently exposed by a QEMU change,
and reported under <https://bugs.launchpad.net/qemu/+bug/1715700>.

Aleksei, can you please fetch the branch, build it, and report back with
your Tested-by if it works for you?

I performed my own tests as well; I'll include those in a separate
email.
