staging: ion: always initialize the free list parameters

Currently we initialize the heap free_lock and free list size in
ion_heap_init_deferred_free, which is only called when the
ION_HEAP_FLAG_DEFER_FREE heap flag is given.  However, the lock and size
are used in the shrinker path as well as the deferred free path, and we
can register a shrinker *without* enabling deferred freeing.  So, if a
heap provides a shrinker but *doesn't* set the DEFER_FREE flag we will
use these parameters uninitialized (resulting in a spinlock bug and
broken shrinker accounting).

Fix these problems by initializing the free list parameters directly in
ion_device_add_heap, which is always called no matter which heap
features are being used.

Smatch complains that "data->ioc_plen2" is a user controlled value and,

very serious because probably the copy_to_user() would return -EFAULT
on every arch that matters instead of creating an info leak.  Also I
haven't followed it through to see if the value is really user

drivers: staging: lustre: Track sign separately

The `mult' parameter is negated if the user data begins with a '-' so
that the final value has the appropriate sign.  But `mult' is only used
if the user data does not include a "units" suffix.  In this case,
`mult' is overridden with the numeric scale conveyed by the units suffix,

Having `mult' serving double-duty works but is confusing.  Use a new

fixes a pitfall of passing 0 to `mult', expecting it to be ignored when
