Variables of type atomic{,64}_t can be used fine with
debugfs_create_u{32,64}, when passing a pointer to the embedded counter.
This allows to get rid of the casts, which prevented compiler checks.

There is no need to cast a typed pointer to a void pointer when calling
a function that accepts the latter. Remove it, as the cast prevents
further compiler checks.

Hi all,
Casting parameters in debugfs_create_*() calls prevents the compiler
from performing some checks.
Hence this patch series removes superfluous casts, or reworks code to no
longer need the casts.
All patches can be applied independently, there are no dependencies.
Thanks for your c

"powerpc_security_features" is "unsigned long", i.e. 32-bit or 64-bit,
depending on the platform (PPC_FSL_BOOK3E or PPC_BOOK3S_64). Hence
casting its address to "u64 *", and calling debugfs_create_x64() is
wrong, and leaks 32-bit of nearby data to userspace on 32-bit platforms.

This is a tentative to switch powerpc/32 vdso to generic C implementation.
It will likely not work on 64 bits or even build properly at the moment.
powerpc is a bit special for VDSO as well as system calls in the
way that it requires setting CR SO bit which cannot be done in C.

A recent commit removed the NULL pointer check from the clock_getres()
implementation causing a test case to fault.
POSIX requires an explicit NULL pointer check for clock_getres() aside of
the validity check of the clock_id argument for obscure reasons.
Add it back for both 32bit and 64bit.
