A task in the kernel (task_mm_cid_work) runs somewhat periodically to
compact the mm_cid for each process. Add a test to validate that it runs
correctly and timely.
The test spawns 1 thread pinned to each CPU, then each thread, including
the main one, runs in short bursts for some time. During thi

Iterating through array of maps may encounter non existing keys. The
batch operation should not fail on when this happens.

These functions are used often, also in selftests.
sscanf() itself is also used by kselftest.h itself.
The implementation is limited and only supports numeric arguments.

This reverts commit 16767502aa990cca2cb7d1372b31d328c4c85b40.
Nolibc gained support for uname(2) and sscanf(3) which are the
dependencies of ksft_min_kernel_version().
So re-enable support for ksft_min_kernel_version() under nolibc.
