Paul Walmsley 2d69fbf3d0 riscv: fix build break after macro-to-function conversion in generic cacheflush.h 
Commit c296d4dc13 ("asm-generic: fix a compilation warning")
converted the various flush_*cache_* macros in
asm-generic/cacheflush.h to static inline functions.  This breaks
RISC-V builds, since RISC-V's cacheflush.h includes the generic
cacheflush.h and then undefines the macros to be overridden.

Fix by copying the subset of the no-op functions that are reused from
the generic cacheflush.h into the RISC-V cacheflush.h, and dropping
the include of the generic cacheflush.h.

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.
