commit 3f93a4f297961c12bb17aa16cb3a4d1291823cae upstream.
It is possible for an irq triggered by channel0 to be received later
after clks are disabled once firmware loaded during sdma probe. If
that happens then clearing them by writing to SDMA_H_INTR won't work
and the kernel

Add a missing EHB (Execution Hazard Barrier) in mtc0 -> mfc0 sequence.
Without this execution hazard barrier it's possible for the value read

The "pending" variable was a u32 but we cast it to an unsigned long
pointer when we do the for_each_set_bit() loop. The problem is that on
big endian 64bit systems that results in an out of bounds read.
