- Update to crash 6.0.7 from upstream and adjust patches to apply
  without offsets. Upstream changes:
  o Enhanced the search command to allow the searched-for value to
    be entered as a crash (expression) or a kernel symbol name. The
    resultant value of an (expression) or kernel symbol value must
    fit into in the designated value size if -w or -h are used, and
    neither variant may be used with the -c option.  If found, both
    the resultant value and the argument input string will be
    displayed next to the target address(es).
  o Added a new "search -t" option that will restrict the search to
    the kernel stack pages of all tasks.  If one or more matches
    are found in a task's kernel stack, the output is preceded with
    a task-identifying header.
  o Fix for the s390x "bt -[tT]" options when run on an active task
    on a live system.  Without the patch, the options fail with the 
    message "bt: invalid/stale stack pointer for this task: 0".
  o Fix for s390x "vm -p" option, which may show invalid user to
    physical address translation data if a page is not mapped.
    Without the patch, a page's translation may indicate
    "<address>   SWAP: (unknown swap location)  OFFSET: 0",
    or show an incorrect swap offset on an actual swap device.
  o Added new "vm -[xd]" options to be used in conjunction with
    "vm -[mv]", which override the current default output format 
    with hexadecimal or decimal format for just the command instance.  
    Without the patch, it would require changing the default output 
    format with "hex" or "dec" prior to executing "vm -[mv]".  The 
    new flags may also be used with "foreach vm -[mv]".
  o Fix for the s390x "vm -p" and "vtop -u <user-address>" commands
    if the page containing the relevant PTE is not mapped.  Without
    the patch, the commands fail with the error message "vm: read
