Yeah, it needs a get_user() that supports 64-bit data.

The problem on powerpc is different though: __get_user_nocheck() and __get_user_check() use unsigned long __gu_val; followed by __get_user_size(__gu_val, __gu_addr, (size), __gu_err); __get_user_size() fails in if (size > sizeof(x)) (x) = __get_user_bad(); Presumably "unsigned long" is 32 bit on 32 bit powerpc, not 64 bit. Overall, the explicit 64-bit use of get_user() seems to be quite unusual. Thanks, Guenter ^ permalink raw reply [flat|nested] 5+ messages in thread

I noticed you've sent a fix for DRM. Doh, and I was just fixing m68k...
