When CONFIG_RELOCATABLE=n, the Linux real mode interrupt handlers call into KVM using real address. This needs to be translated to the kernel linear effective address before the MMU is switched on. kvmppc_bad_host_intr misses adding these bits, so when it is used to handle a system reset interrupt (that always gets delivered in real mode), it results in an instruction access fault immediately after the MMU is turned on. Fix this by ensuring the top 2 address bits are set when the MMU is turned on. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Paul Mackerras <paulus@ozlabs.org>
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.
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.
