The recently added MIPS cacheinfo support used a macro populate_cache()
to populate the cacheinfo structures depending on which caches are
present. However the macro contains multiple statements without
enclosing them in a do {} while (0) loop, so the L2 and L3 cache
conditionals in populate_cache_leaves() only conditionalised the first
statement in the macro.
This overflows the buffer allocated by detect_cache_attributes(),
resulting in boot failures under QEMU where neither the L2 or L2 caches
are present.
Enclose the macro statements in a do {} while (0) block to keep the
whole macro inside the conditionals.

README
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.
