Hi,
There is a binutils bug (as) which produces bad addresses when
getting the address of a struct member for initializing the same struct,
and when there is data or static functions declared before:
int test = 0xdeadbeef;
struct {
int dummy;
void *ptr;
} bug =
{
ptr: &bug.ptr
};
will produce bad value for bug.ptr.
This patch move the declaration of kswapd_wait as a workaround to
this compiler bug. This probably affects all mips64 kernels.
Vivien Chappelier.
