The type 'enum kvm_reg_ex' is an extension of 'enum kvm_reg', however
the extension is only semantical and the compiler doesn't know about the
relationship between the two types. In kvm_pdptr_read() a value of the
extended type is passed to kvm_x86_ops->cache_reg(), which expects a
value of the base type. Clang raises the following warning about the
type mismatch:
arch/x86/kvm/kvm_cache_regs.h:44:32: warning: implicit conversion from
enumeration type 'enum kvm_reg_ex' to different enumeration type
'enum kvm_reg' [-Wenum-conversion]
kvm_x86_ops->cache_reg(vcpu, VCPU_EXREG_PDPTR);
Cast VCPU_EXREG_PDPTR to 'enum kvm_reg' to make the compiler happy.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
