When KVM emulates VMX store, it will invoke kvmppc_get_vmx_data() to retrieve VMX reg val. kvmppc_get_vmx_data() will check mmio_host_swabbed to decide which double word of vr[] to be used. But the mmio_host_swabbed can be uninitialized during VMX store procedure: kvmppc_emulate_loadstore \- kvmppc_handle_store128_by2x64 \- kvmppc_get_vmx_data So vcpu->arch.mmio_host_swabbed is not meant to be used at all for emulation of store instructions, and this patch makes that true for VMX stores. This patch also initializes mmio_host_swabbed to avoid possible future problems. Signed-off-by: Simon Guo <wei.guo.simon@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.
