Integrating the following commit(s) to linux-yocto/6.1:
4675ec8d0b9a kernel/sched: Fix uninitialized read in nohz_full/isolcpus setup
The carry forward of commit from the v5.15 linux-yocto kernel:
https://git.yoctoproject.org/linux-yocto/commit/?id=97c96388922
...in which case the sanity checks are properly *after* the allocation
and processing of the bootargs into the cpumask.
However, it seems patch (or wiggle?) apparently decided to put the
sanity checks *before* the population of the cpumask during the
carry-forward and generation of the new v6.1 kernel. Meaning they are
validating uninitialized memory and hence nohz_full= and isolcpus= are
subject to random failures even for valid input ranges.
