From: Arnd Bergmann <arnd@xxxxxxxx> The get_user()/put_user() functions are meant to check for access_ok(), while the __get_user()/__put_user() functions don't. This broke in 4.19 for nds32, when it gained an extraneous check in __get_user(), but lost the check it needs in __put_user().
Can we follow the lead of MIPS (which this was originally copied from I think) and kill the pointless __get/put_user_check wrapper that just obsfucate the code?
