Yeah, will do, but out of curios

From: "Paul E. McKenney"
CONFIG_NO_HZ_FULL doesn't make sense without CONFIG_CPU_ISOLATION. In
fact enabling the first without the second is a regression as nohz_full=
boot parameter gets silently ignored.
Besides this unnatural combination hangs RCU gp kthread when running
rcutorture for reason

The "isolcpus=" and "nohz_full=" boot parameters depend on CPU Isolation
support. Let's document that.

The "isolcpus=" boot parameter support was always built-in before we
moved the related code under CONFIG_CPU_ISOLATION. Having it disabled by
default is very confusing for people accustomed to use this parameter.
So enable it by dafault to keep the previous behaviour but keep it
optable for those

fix typo in assignment of fs default overflow gid
The patch remains without practical effect since
both macros carry identical values.
Still, it might become a problem in the future
if (for whatever reason) the default overflow uid
and gid differ.
The DEFAULT_FS_OVERFLOWGID macro was previously un
