32-bit kernels can be configured to support MIPS64, in which case neither CONFIG_64BIT or CONFIG_CPU_MIPS32_R* will be set. This causes the CP0_Status.FR checks at the point of floating point register save and restore to be compiled out, which results in odd FP registers not being saved or restored to the task or signal context even when CP0_Status.FR is set. Fix the ifdefs to use CONFIG_CPU_MIPSR2 and CONFIG_CPU_MIPSR6, which are enabled for the relevant revisions of either MIPS32 or MIPS64, along with some other CPUs such as Octeon (r2), Loongson1 (r2), XLP (r2), Loongson 3A R2.

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.
