x86: avoid dereferencing beyond stack + THREAD_SIZE
commit e1e23bb0513520035ec934fa3483507cb6648b7c upstream
x86: avoid dereferencing beyond stack + THREAD_SIZE
It's possible for get_wchan() to dereference past task->stack + THREAD_SIZE
while iterating through instruction pointers if fp equals the upper boundary,
causing a kernel panic.
