Subject: cpumask: limit visibility of FORCE_NR_CPUS
Date: Wed, 16 Nov 2022 09:24:51 -0800
In current form, FORCE_NR_CPUS is visible to all users building their
kernels, even not experts. It is also set in allmodconfig or
allyesconfig, which is not a correct behavior.
This patch fixes it. It also changes the parameter short description:
removes implementation details and highlights the effect of the change.
