Michal Luczaj 4ac5b42377 KVM: x86: emulator: Fix illegal LEA handling 
The emulator mishandles LEA with register source operand. Even though such
LEA is illegal, it can be encoded and fed to CPU. In which case real
hardware throws #UD. The emulator, instead, returns address of
x86_emulate_ctxt._regs. This info leak hurts host's kASLR.

Tell the decoder that illegal LEA is not to be emulated.

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.
