commit 4089f37cdd776e046d51604041c3fe62a2bc1435
Author: Justus Winter <address@hidden>
Date:   Sun Mar 12 17:16:40 2017 +0100

    Pass the kernel's task port to proc.
    
    Previously, the early server bootstrap relied upon a specific task
    layout to determine the kernels task port.  Explicitly pass it from
    the kernel instead.
    
    * boot/boot.c (default_boot_script): Add '--kernel-task' parameter to
    ext2fs.
    (main): New bootscript variable 'kernel-task'.
    * libdiskfs/boot-start.c (diskfs_kernel_task): Declaration variable.
    (diskfs_start_bootstrap): If '--kernel-task' was given to us, pass it
    along to startup.
    * libdiskfs/opts-std-startup.c (diskfs_kernel_task): New variable.
    (startup_options): Add '--kernel-task' option.
    (parse_startup_opt): Handle option.
    * proc/main.c (kernel_task): New variable.
    (OPT_KERNEL_TASK): New macro.
    (options): New variable.
    (parse_opt): New function.
    (main): Parse options.  Use 'kernel_task' if provided.
    * release/servers.boot: Add '--kernel-task' parameter to ext2fs.
    * startup/startup.c (OPT_KERNEL_TASK): New macro.
    (options): Add '--kernel-task' option.
    (kernel_task): New variable.
    (insert_ports_fnc_t): New declaration.
    (run): Add argument for a function that inserts rights into the newly
    created task and adds arguments to the argument vector.
    (argz_task_insert_right): New function.
    (proc_insert_ports): Likewise.
    (parse_opt): New function.
    (main): Pass the kernel's task port to proc.
    (frob_kernel_process): Use the kernel's task port.

    startup: Simplify reference handling.
    
    * startup/startup.c (launch_core_servers): Instead of copying a send
    right and then deallocating it, move it.
    (init_stdarrays): Likewise.
