When building for microMIPS we need to ensure that the assembler always knows that there is code at the target of a branch or jump. Commit7170bdc777("MIPS: Add return errors to protected cache ops") introduced a fixup path to protected_cache(e)_op() which does not meet this requirement. The fixup path jumps to the "2" label but the .section pseudo-op immediately following it causes the label to be marked as data. Linking then fails with: mips-img-linux-gnu-ld: arch/mips/mm/c-r4k.o: .fixup+0x0: Unsupported jump between ISA modes; consider recompiling with interlinking enabled. Fix this by declaring that "2" labels code using the .insn directive.

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.
