Don't bother unprotecting the target gfn if EMULTYPE_WRITE_PF_TO_SP is set, as KVM will simply report the emulation failure to userspace. This will allow converting reexecute_instruction() to use kvm_mmu_unprotect_gfn_instead_retry() instead of kvm_mmu_unprotect_page().

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.
