    mm: ipipe: disable ondemand memory · 10d5726c
    Philippe Gerum authored and Greg Gallagher's avatar Greg Gallagher committed
    Co-kernels cannot bear with the extra latency caused by memory access
    faults involved in COW or overcommit. __ipipe_disable_ondemand_mappings()
    force commits all common memory mappings with physical RAM.
    
    In addition, the architecture code is given a chance to pre-load page
    table entries for ioremap and vmalloc memory, for preventing further
    minor faults accessing such memory due to PTE misses (if that ever
    makes sense for them).
