Take "enum kvm_only_cpuid_leafs" in scattered specific CPUID helpers
(which is obvious in hindsight), and use "unsigned int" for leafs that
can be the kernel's standard "enum cpuid_leaf" or the aforementioned
KVM-only variant. Loss of the enum params is a bit disapponting, but
gcc obviously isn't providing any extra sanity checks, and the various
BUILD_BUG_ON() assertions ensure the input is in range.
This fixes implicit enum conversions that are detected by clang-11:
arch/x86/kvm/cpuid.c:499:29: warning: implicit conversion from enumeration type 'enum kvm_only_cpuid_leafs' to different enumeration type 'enum cpuid_leafs' [-Wenum-conversion]
kvm_cpu_cap_init_scattered(CPUID_12_EAX,

README
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.
