commit 18906ff9af6517c20763ed63dab602a4150794f7 upstream. Recently, we reworked a lot of code to consistentlt pass ESR_ELx as a 64-bit quantity. However, we missed that this can be passed into die() and __die() as the 'err' parameter where it is truncated to a 32-bit int. As notify_die() already takes 'err' as a long, this patch changes die() and __die() to also take 'err' as a long, ensuring that the full value of ESR_ELx is retained. At the same time, die() is updated to consistently log 'err' as a zero-padded 64-bit quantity. Subsequent patches will pass the ESR_ELx value to die() for a number of exceptions.

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.
