In x86's debug_regs test, change the RDMSR(MISC_ENABLES) in the single-step testcase to a WRMSR(TSC_DEADLINE) in order to verify that KVM honors KVM_GUESTDBG_SINGLESTEP when handling a fastpath VM-Exit. Note, the extra coverage is effectively Intel-only, as KVM only handles TSC_DEADLINE in the fastpath when the timer is emulated via the hypervisor timer, a.k.a. the VMX preemption timer.

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 reStructuredText 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.
