This removes the checks for the FP/VMX/VSX enable bits in the MSR from analyse_instr() and adds them to emulate_step() instead. The reason for this is that we may want to use analyse_instr() in a situation where the FP/VMX/VSX register values are stored in the current thread_struct and the FP/VMX/VSX enable bits in the MSR image in the pt_regs are zero. Since analyse_instr() doesn't make any changes to register state, it is reasonable for it to indicate what the effect of an instruction would be even though the relevant enable bit is off.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
