When trying to build this for a 64-bit platform, one gets warnings from using IS_ERR_VALUE on something which is not sizeof(long). Instead, change the various *_offset fields to store a signed integer, and simply check for a negative return from qe_muram_alloc(). Since qe_muram_free() now accepts and ignores a negative argument, we only need to make sure these fields are initialized with -1, and we can just unconditionally call qe_muram_free() in ucc_slow_free(). Note that the error case for us_pram_offset failed to set that field to 0 (which, as noted earlier, is anyway a bogus sentinel value).

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.
