Stop compiling sev.c when CONFIG_KVM_AMD_SEV=n, as the number of #ifdefs in sev.c is getting ridiculous, and having #ifdefs inside of SEV helpers is quite confusing. To minimize #ifdefs in code flows, #ifdef away only the kvm_x86_ops hooks and the #VMGEXIT handler. Stubs are also restricted to functions that check sev_enabled and to the destruction functions sev_free_cpu() and sev_vm_destroy(), where the style of their callers is to leave checks to the callers. Most call sites instead rely on dead code elimination to take care of functions that are guarded with sev_guest() or sev_es_guest().

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.
