preempt_count in struct thread_info is unsigned int, but the entry.S code used LDREG, which generates a 64 bit load when compiled for 64 bit. Fix this to use an ldw and also change the condition in the compare one line below to only compares 32 bits, although ldw zero extends, and that should work with a 64 bit compare.

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.
