The new __kvm_faultin_pfn() function is upset by the fact that e500 KVM ignores host page permissions - __kvm_faultin requires a "writable" outgoing argument, but e500 KVM is nonchalantly passing NULL. If the host page permissions do not include writability, the shadow TLB entry is forcibly mapped read-only. 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 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.
