We deprecated '%pF/%pf' printk specifiers, since '%pS/%ps' is now smart
enough to handle function pointer dereference on platforms where such
dereference is required.

Call appropriate function descriptor dereference ARCH callbacks:
- dereference_kernel_function_descriptor() if the pointer is a
kernel symbol;
- dereference_module_function_descriptor() if the pointer is a
module symbol.
This patch also removes dereference_function_descriptor() from
'%pF/%pf'
We are moving towards separate kernel and module function descriptor
dereference callbacks. This patch enables it for parisc64.

There are two format specifiers to print out a pointer in symbolic
format: '%pS/%ps' and '%pF/%pf'. On most architectures, the two
mean exactly the same thing, but some architectures (ia64, ppc64,
parisc64) use an indirect pointer for C function pointers, where
the function pointer points to a func
Convert dereference_function_descriptor() to accept and return
`unsigned long'. There will be two new ARCH function for kernel
and module function pointer dereference, which will work with
`unsigned long', so the patch unifies interfaces.
Besides, dereference_function_descriptor() mostly work with

Petr, could you please pick up the series?

On some arches C function pointers are indirect and point to
a function descriptor, which contains the actual pointer to the code.

Provide a new command allowing processes to register their intent to use
the private expedited command.
This allows PowerPC to skip the full memory barrier in switch_mm(), and
only issue the barrier when scheduling into a task belonging to a
process that has registered to use expedited private.

Hi Abdul,
I just want to follow up with this.
Did you have a chance to test my patch? Does it fix your original problem?
Thanks.

Applied to powerpc fixes, thanks.

In case, someone wishes for a changelog:
With fadump_rework_cmdline_params() function, parse_args() callback
function,
taking new arguments - current & next, use them to process
