[PATCH] Fix CONFIG_PROCFS=n

From: Manfred Spraul <manfred@colorfullife.com>

three build fixes for CONFIG_PROC_FS=n:

include/linux/procfs.h:

 - add missing proc_pid_unhash, proc_pid_flush declarations.  static
   inline functions that do nothing.

 - move semicolons around for kclist_{add,del}.  gcc-3.2.2 doesn't like
   the current syntax.

drivers/net/pppoe.c:

 - proc_net doesn't exist if CONFIG_PROC_FS=n.

drivers/scsi/scsi_priv.h:

 - add missing brackets to macro definition.
