kvm_update_cpuid_runtime() mangles CPUID data coming from userspace VMM after updating 'vcpu->arch.cpuid_entries', this makes it impossible to compare an update with what was previously supplied. Introduce __kvm_update_cpuid_runtime() version which can be used to tweak the input before it goes to 'vcpu->arch.cpuid_entries' so the upcoming update check can compare tweaked data. No functional change intended. Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Message-Id: <20220117150542.2176196-2-vkuznets@redhat.com> 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.
