Define and undefine the F() and SF() macros precisely around
kvm_set_cpu_caps() to make it all but impossible to use the macros outside
of kvm_cpu_cap_{mask,init_kvm_defined}(). Currently, F() is a simple
passthrough, but SF() is actively dangerous as it checks that the scattered
feature is supported by the host kernel.
And usage outside of the aforementioned helpers will run afoul of future
changes to harden KVM's CPUID management.
Opportunistically switch to feature_bit() when stuffing LA57 based on raw
hardware support.
No functional change intended.

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.
