Move id and ref_obj_id fields after scalar data section (var_off and ranges). This is necessary to simplify next patch which will change regsafe()'s logic to be safer, as it makes the contents that has to be an exact match (type-specific parts, off, type, and var_off+ranges) a single sequential block of memory, while id and ref_obj_id should always be remapped and thus can't be memcp()'ed. There are few places that assume that var_off is after id/ref_obj_id to clear out id/ref_obj_id with the single memset(0). These are changed to explicitly zero-out id/ref_obj_id fields. Other places are adjusted to preserve exact byte-by-byte comparison behavior. No functional changes.

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.
