  • 72680a191   pids: increase pid_max based on num_possible_cpus ... Browse Code »

    On a system with a substantial number of processors, the early default
    pid_max of 32k will not be enough. A system with 1664 CPU's, there are
    25163 processes started before the login prompt. It's estimated that with
    2048 CPU's we will pass the 32k limit. With 4096, we'll reach that limit
    very early during the boot cycle, and processes would stall waiting for an
    available pid.

    This patch increases the early maximum number of pids available, and
    increases the minimum number of pids that can be set during runtime.

  • 278d1ed65   cpumask: make CONFIG_NR_CPUS always valid. ... Browse Code »

    Impact: cleanup

    Currently we have NR_CPUS, which is 1 on UP, and CONFIG_NR_CPUS on
    SMP. If we make CONFIG_NR_CPUS always valid (and always 1 on !SMP),
    we can skip the middleman.

    This also allows us to find and check all the unaudited NR_CPUS usage
    as we prepare for v. large NR_CPUS.

    To avoid breaking every arch, we cheat and do this for the moment
    in the header if the arch doesn't.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
