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.
Cheers,
Will
