In the Linux kernel, the following vulnerability has been resolved:
hwmon: (powerz) Avoid cacheline sharing for DMA buffer
Depending on the architecture the transfer buffer may share a cacheline with the following mutex. As the buffer may be used for DMA, that is problematic.
Use the high-level DMA helpers to make sure that cacheline sharing can not happen.
Also drop the comment, as the helpers are documentation enough.
