commit 93fce954427effee89e44a976299b15dd75b4bbc upstream.
At the end of the function we expect "status" to be zero, but it's
either -EINVAL or uninitialized.
Fixes: 788bf83db301 ('drm/amdkfd: Add wave control operation to debugger')

drm/amdkfd: Remove unnecessary cast in kfree2016-01-28T12:40:11ZAmitoj Kaur Chawla2016-01-25T17:33:57Zurn:sha1:642f0f2a1563b5ab6f5de896f602177ac1f06652
Remove an unnecassary cast in the argument to kfree.
Found using Coccinelle. The semantic patch used to find this is as follows:
//<smpl>
@@
type T;
expression *f;
@@
- kfree((T *)(f));
+ kfree(f);
//</smpl>

The latter is a default version of <asm/mman.h> and not for driver use.

A logical AND operation was used during mask and shift, instead of a
bitwise AND operation. This patch fixes this bug by changing the
operation to bitwise AND.

The MAP_QUEUES packet length for Carrizo is different than for Kaveri.
Therefore, we now need to calculate the runlist length with regard to the
underlying H/W.
