Subject[PATCH 5.15 005/136] parisc: Make CONFIG_64BIT available for ARCH=parisc64 only
Date
From: Helge Deller <deller@gmx.de>

commit 3dcfb729b5f4a0c9b50742865cd5e6c4dbcc80dc upstream.

With this patch the ARCH= parameter decides if the
CONFIG_64BIT option will be set or not. This means, the
ARCH= parameter will give:

ARCH=parisc -> 32-bit kernel
ARCH=parisc64 -> 64-bit kernel

This simplifies the usage of the other config options like
randconfig, allmodconfig and allyesconfig a lot and produces
the output which is expected for parisc64 (64-bit) vs. parisc (32-bit).

- Enable this if you want to support 64bit kernel on PA-RISC platform.

- At the moment, only people willing to use more than 2GB of RAM,
