I've pushed this out to for-next/ptr-auth with the following changes:

* Rebased onto for-next/core
* Dropped the GET/SET ptrace requests for now, due to fragile regset usage
* Moved the user key state from thread_info to thread_struct
* Removed use of VA_BITS for the PAC mask (doesn't work with 52-bit user VAs)
* Added a patch to use _BITUL for the bit definitions in sysreg.h
* Tidied up the HWCAP generation [need to run this past Suzuki]
* Reduced the number of CPU caps from 6 to 4 [also need to run past Suzuki]
* Added Reviewed-by tags

I've not merged it into for-next/core yet, because it could use some testing
and review first.
