As per the ABI batch_len is u32, however if the batch_len is left unset,
then the kernel will just assume batch_len is the size of the whole
batch object, however since the vma->size is u64, while the batch_len is
just u32 we can end up with batch_len = 0 if we are given too large batch
object(e.g 1ULL << 32), which doesn't look the intended behaviour and
probably leads to explosions on some HW.

Nah. That's setting exec_len used for dispatch, not for parsing, which
is still using
i915_gem_execbuffer_parse(engine, &shadow_exec_entry,
params->batch->obj,
eb,
args->batch_start_offset,
args->batch_len,
drm_is_current_master(file));
(and args->batch_len is straight from userspace and passed onwards)
It's right up until 435e8fc059db ("drm/i915: Allow parsing of unsized batches")
where we are using the user value of batch_len for allocating the shadow
object and parsing.

It should not have caused the cmdparser any trouble though, it should
have been quite happy to copy nothing and reject the batch for reaching
the end too early (with a very slim chance of a stale
MI_BATCH_BUFFER_END to the rescue).
intel_gt_get_buffer_pool() looks suspect given a size of 0, it will
either give the largest object it has cached or break upon
creating/allocating internal pages.
In terms of HW fail, only gen2 used the parameter and it has a very
limited batch/GTT size.

And we shouldn't fail here. So bump to u64, and since the vma->size
cannot be larger than the GTT, we will be safe for gen2 where it makes a
difference.

On the topic of that patch, why is it looking at args->batch_len(might
be zero), even though it looks like it is trying to move the
eb->batch_len calculation to before we call eb_use_cmdparser(), so it
can use it(the commit message seems to suggest that?), but then it only
looks at the args version anyway. I don't get it.
