The main theme of this series is to kill off kvm_arch_init(), kvm_arch_hardware_(un)setup(), and kvm_arch_check_processor_compat(), which all originated in x86 code from way back when, and needlessly complicate both common KVM code and architecture code. E.g. many architectures don't mark functions/data as __init/__ro_after_init purely because kvm_init() isn't marked __init to support x86's separate vendor modules. The idea/hope is that with those hooks gone (moved to arch code), it will be easier for x86 (and other architectures) to modify their module init sequences as needed without having to fight common KVM code. E.g. I'm hoping that ARM can build on this to simplify its hardware enabling logic, especially the pKVM side of things. There are bug fixes throughout this series. They are more scattered than I would usually prefer, but getting the sequencing correct was a gigantic pain for many of the x86 fixes due to needing to fix common code in order for the x86 fix to have any meaning. And while the bugs are often fatal, they aren't all that interesting for most users as they either require a malicious admin or broken hardware, i.e. aren't likely to be encountered by the vast majority of KVM users. So unless someone _really_ wants a particular fix isolated for backporting, I'm not planning on shuffling patches. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
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.
