Apologies for the problems you've seen.  You've clearly hit something of
a sweet spot (or should that be sour-spot?) for compiling in ways I
don't do as routinely as I should.

I've attached a set of patches that should resolve all the problems you
describe.  Unfortunately until I can test more thoroughly on our IA64
hardware I've marked the acceleration modules as requiring CONFIG_X86,
so this will prevent these modules from being used on IA64 systems for
the time being. 

The patches are as follows:

sfc_net_static_compile
 - fix the namespace clash problem from the module paramenters when
compiling the plugins statically into the kernel.

debugfs_create_u64
 - move the debugfs_create_u64 which had duplicate implementations in
each plugin into the standard Linux debugfs files.

sfc_debugfs_off_compile
 - Fix compile error when not selecting CONFIG_SFC_DEBUGFS

sfc_config_x86_dependency
 - Specify module "depends on" to more accurately describe what the real
dependencies are.
  
IA64_PRIx64
 - fix the definition of PRIx64 in the sfc modules to be properly
defined on IA64 architectures.

Thanks 

Kieran
