I am focussing on UAPI headers which include libc headers. virtio_ring.h seems to be the only such header which uses uintptr_t. There are a few other UAPI headers which reference uintptr_t, but only in comments or macros. uintptr_t in regular kernel code is out of scope for me. While it is iffy, it doesn't actually hurt.
