Instead of converting the physical address of the tmpalias mapping to the tlb insert format inside all the various tmpalias functions, move this conversion over to the DTLB miss handler. The physical address is already in %r26 (or will be calculated into %r23), so there are no additional steps needed in the functions themselves. Additionally use the dep_safe() and depi_safe() macros to avoid differentiating between 32- and 64-bit builds and as such make the code much more readable. The check if "ldil L%(TMPALIAS_MAP_START)" will sign extend into the upper 32 bits can be dropped, because we added a compile time check in an earlier patch.

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.
