Fix following warnings:
kernel/signal_64.c:292:16: warning: incorrect type in assignment (different address spaces)
kernel/signal_64.c:378:24: warning: cast removes address space of expression
kernel/signal_64.c:386:24: warning: cast removes address space of expression
rwin_save declared __user - because is points to user data.
Drop cast of pointer to u64 in calls to __put_user.
Pointers are 64 bits and __put_user supports pointers too.
