Hello,

I'm hitting
Unhandled fault: page domain fault (0x81b) at 0x00e41008

which is related to CPU_SW_DOMAIN_PAN
commit a5e090acbf545c0a3b04080f8a488b17ec41fe02


I see that __copy_from_user() is now wrapped in
uaccess_save_and_enable ... uaccess_restore

I'm not using __copy_from_user() because I'm implementing block
copies with specific access size.

Can I just wrap my block copy functions in
uaccess_save_and_enable ... uaccess_restore
like __copy_from_user?

Regards.
