- Fix prototypes for debugfs functions (in configurations where

The current <linux/debugfs.h> include file is a little fragile in that
it is not self-contained and hence may cause compile warnings or
errors depending on the files included before it, the kernel config
and the architecture.  This patch makes things a little more robust by:

 - including <linux/types.h> to get definitions of u32, mode_t, and so on.
 - forward declaring struct file_operations.
 - including <linux/err.h> when CONFIG_DEBUG_FS is not set

The last change is particularly useful, as a kernel developer is
likely to build with debugfs always enabled and never see the build
breakage cased if debugfs is disabled.

platform_add_devices can be used from within modules, so it should be
exported.  This can for example happen if you have hotpluggable firmware in
an FPGA on a system on chip processor; in our case the FPGA is probed for
devices and the FPGA base code registers the devices it has found with the
kernel.  

(akpm: I think this is reasonable from a licensing POV: it's unlikely that
anyone would be interested in merging such specialised modules into mainline,
and it's a GPL export).

Here we add a TIMEOUT value to the hotplug environment of the firmware
requesting event. I will adapt udevd not to wait for anything else, if
it finds a TIMEOUT key.

Like Alpha, sparc64's struct stat was defined before we had the
nanosecond et al.  fields added.  So like Alpha I have to cons up a
struct stat64 to get this stuff.  I'll work on the glibc bits soon. 

Also, we were forgetting to fill in the nanosecond fields in the sparc
compat stat64 syscalls.

Done with "git-pull-script rsync://www.parisc-linux.org/~jejb/scsi-rc-fixes-2.6.git"
together with an automated content merge.

Now that we export all the parameters, this is easy to do.
It also means that we can dump about 2000 lines of code that
were dedicated to doing this internally.

Additionally, this removes all the aic7xxx driver abuse
of SCSI timers which were embedded in the DV routines.

  Don't use cmd->request->nr_hw_segments as it may not be initialized
  (SG_IO in particular bypasses anything that initializes this and just
  uses scsi_do_req to insert a scsi_request directly on the head of the
  queue) and a bogus value here can trip up the checks to make sure that
  the number of segments will fit in the queue ring buffer, resulting in
  commands that are never completed.

  Fix up several issues with PCI DMA mapping and failure to check return
  values on the mappings.

  Make the check for space in the ring buffer happen after the DMA mapping
  is done since any checks done before the mapping has taken place are
  bogus.

This adds 32-bit compatibility for mounting an NFSv4 mount on a 64-bit
kernel (such as happens with PPC64). 

The problem is that the mount data for the NFS4 mount process includes
auxilliary data pointers, probably because the NFS4 mount data may
conceivably exceed PAGE_SIZE in size - thus breaking against the hard
limit imposed by sys_mount().

This fixes a deadlock on the dcache lock detected during testing at IBM
by moving the logging of the current executable information from the
SELinux avc_audit function to audit_log_exit (via an audit_log_task_info
helper) for processing upon syscall exit. 

For consistency, the patch also removes the logging of other
task-related information from avc_audit, deferring handling to
audit_log_exit instead. 

This allows simplification of the avc_audit code, allows the exe
information to be obtained more reliably, always includes the comm
information (useful for scripts), and avoids including bogus task
information for checks performed from irq or softirq.
