Hi all,
There are still two format specifiers that print unhanced kernel
addresses, potentially leaking sensitive information regarding the
kernel layout in memory.
This patch series fixes this by printing hashed addresses instead.
Changes compared to v1:
- Get rid of the forward declaration for ptr_to_id(),
- Add Reviewed-by.
Thanks!

lib/vsprintf: Prepare for more general use of ptr_to_id()
lib/vsprintf: Hash legacy clock addresses
lib/vsprintf: Hash printed address for netdev bits fallback
