      usermodehelper: Tidy up waiting · 86313c48
      Jeremy Fitzhardinge authored
      Rather than using a tri-state integer for the wait flag in
      call_usermodehelper_exec, define a proper enum, and use that.  I've
      preserved the integer values so that any callers I've missed should
      still work OK.

      Add common orderly_poweroff() · 10a0a8d4
      Jeremy Fitzhardinge authored
      Various pieces of code around the kernel want to be able to trigger an
      orderly poweroff.  This pulls them together into a single
      implementation.
      
      By default the poweroff command is /sbin/poweroff, but it can be set
      via sysctl: kernel/poweroff_cmd.  This is split at whitespace, so it
      can include command-line arguments.
      
      This patch replaces four other instances of invoking either "poweroff"
      or "shutdown -h now": two sbus drivers, and acpi thermal
      management.
      
      sparc64 has its own "powerd"; still need to determine whether it should
      be replaced by orderly_poweroff().

      usermodehelper: split setup from execution · 0ab4dc92
      Jeremy Fitzhardinge authored
      Rather than having hundreds of variations of call_usermodehelper for
      various pieces of usermode state which could be set up, split the
      info allocation and initialization from the actual process execution.
      
      This means the general pattern becomes:
       info = call_usermodehelper_setup(path, argv, envp); /* basic state */
       call_usermodehelper_<SET EXTRA STATE>(info, stuff...);	/* extra state */
       call_usermodehelper_exec(info, wait);	/* run process and free info */
      
      This patch introduces wrappers for all the existing calling styles for
      call_usermodehelper_*, but folds their implementations into one.

      add argv_split() · d84d1cc7
      Jeremy Fitzhardinge authored
      argv_split() is a helper function which takes a string, splits it at
      whitespace, and returns a NULL-terminated argv vector.  This is
      deliberately simple - it does no quote processing of any kind.
      
      [ Seems to me that this is something which is already being done in
        the kernel, but I couldn't find any other implementations, either to
        steal or replace.  Keep an eye out. ]

      add kstrndup · 1e66df3e
      Jeremy Fitzhardinge authored
      Add a kstrndup function, modelled on strndup.  Like strndup this
      returns a string copied into its own allocated memory, but it copies
      no more than the specified number of bytes from the source.
      
      Remove private strndup() from irda code.

      zs: move to the serial subsystem · 8b4a4080
      Maciej W. Rozycki authored
      This is a reimplementation of the zs driver for the serial subsystem.  Any
      resemblance to the old driver is purely coincidential.  ;-) I do hope I got
      the handling of modem lines right -- better do not tackle me about the
      issue unless you feel too good...
      
      Any users of the old driver: please note the numbers of the serial lines
      have now been swapped, i.e.  ttyS0 <-> ttyS1 and ttyS2 <-> ttyS3.  It has
      to do with the modem lines mentioned above; basically the port A in a given
      chip has to be initialised before the port B if you want to use the latter
      as the serial console (which is usually the case), as operations on modem
      lines of the serial line associated with the port B access both ports (see
      the comment at the top of the driver for the details of wiring used).
      Please update your scripts.
      
      This is also the reason each SCC now requests an IRQ once only (as seen in
      "/proc/interrupts") -- the handler takes care of both ports at once as the
      line associated with the port B has to take status update interrupts from
      both ports (and yet the line of the port A takes its own for itself too).
      The old driver never got it right...

      dm: fix memory leak in dm_create_persistent() when starting metadata update thread fails · 851a8a7f
      Jesper Juhl authored
      If, in dm_create_persistent(), the call to create_singlethread_workqueue()
      fails then we'll return without freeing the memory allocated to 'ps', thus
      leaking sizeof(struct pstore) bytes.  This patch fixes the leak.
