commit 7e99a6ba690f27b36e99144178c71f0687b07ad9
Author: Jo-Philipp Wich <jo at mein.io>

    target: disable CONFIG_PROC_PAGE_MONITOR on most targets
    
    Disable CONFIG_PROC_PAGE_MONITOR in most places and only keep it enabled
    for virtual targets such as malta or potent ones like x86.
    
    This saves up to 4KB of uncompressed kernel size and significantly
    decreases CPU load under certain workloads.
