Hi !
You are trying to use gcc 4.2, aren't you ?
`fault_in_pages_readable' is defined as follows:
fault_in_pages_readable(const char __user *uaddr, int size)
{
volatile char c;
int ret;
ret = __get_user(c, uaddr);
...
}
this invokes the __get_user_nocheck(c,uaddr,sizeof(*uaddr)) macro:
#define __get_user_nocheck(x,ptr,size) \
({ \
__typeof(*(ptr)) __gu_val = (__typeof(*(ptr))) 0; \
... \
})
defining `__gu_val' of type `const char', which gcc 4.2 (don't know about 4.1)
no longer accepts as asm-output (lvalue). At least until this macro will be
changed, you should switch back to gcc 4.0.
kind regards
