Drop the WARN in KVM_RUN that asserts that KVM isn't using the hypervisor timer, a.k.a. the VMX preemption timer, for a vCPU that is in the UNINITIALIZIED activity state. The intent of the WARN is to sanity check that KVM won't drop a timer interrupt due to an unexpected transition to UNINITIALIZED, but unfortunately userspace can use various ioctl()s to force the unexpected state. Drop the sanity check instead of switching from the hypervisor timer to a software based timer, as the only reason to switch to a software timer when a vCPU is blocking is to ensure the timer interrupt wakes the vCPU, but said interrupt isn't a valid wake event for vCPUs in UNINITIALIZED state *and* the interrupt will be dropped in the end.

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.
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.
