The object size sanity checking macros that uaccess.h and uio.h use have been living in thread_info.h for historical reasons. Needing to use jump labels for these checks, however, introduces a header include loop under certain conditions. The dependencies for the object checking macros are very limited, but they are used by separate header files, so introduce a new header that can be used directly by uaccess.h and uio.h. As a result, this also means thread_info.h (which is rather large) and be removed from those headers.

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 reStructuredText 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.
