From: Arnd Bergmann <arnd@xxxxxxxx> sparc64 uses address space identifiers to differentiate between kernel and user space, using ASI_P for kernel threads but ASI_AIUS for normal user space, with the option of changing between them. As nothing really changes the ASI any more, just hardcode ASI_AIUS everywhere. Kernel threads are not allowed to access __user pointers anyway.

I think you somehow missed the Kconfig change, and also the related sparc32 change which continue to have set_fs() after this patch. I did not manage to review the patch - as I am too unfamiliar with the code paths and the set_fs() removal changes. Sam
