commit7455a83276upstream. Commit13db77347d("KVM: x86: don't notify userspace IOAPIC on edge EOI") said, edge-triggered interrupts don't set a bit in TMR, which means that IOAPIC isn't notified on EOI. And var level indicates level-triggered interrupt. But commit3159d36ad7("KVM: x86: use generic function for MSI parsing") replace var level with irq.level by mistake. Fix it by changing irq.level to irq.trig_mode.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
