With the current kfd memory accounting scheme, kfd applications
can use up to 15/16 of total system memory. For system which
has small total system memory size it leaves small system memory
for OS. For example, if the system has totally 16GB of system
memory, this scheme leave OS and non-kfd applications only 1GB
of system memory. In many cases, this leads to OOM killer.
This patch changed the KFD system memory accounting scheme.
15/16 of free system memory when kfd driver load. This deduct
the system memory that OS already use.

get_num_acc_vgprs does not set status.scc if the number of acc vgprs
is 0, so use an and instruction to set the condition code.
The Aldebaran handler binary was not based on the latest version of
the sources, so this update to the binary is the minimal change only
adding two instructions to set the condition code.
A newer version of the handler should be generated and tested in
another commit.
