Summary
intel_th: msu: Fix vmalloced buffers
Details

In the Linux kernel, the following vulnerability has been resolved:

intel_th: msu: Fix vmalloced buffers

After commit f5ff79fddf0e ("dma-mapping: remove CONFIGDMAREMAP") there's a chance of DMA buffer getting allocated via vmalloc(), which messes up the mmapping code:

RIP: mscmmapfault [intelthmsu] Call Trace: <TASK> __dofault dofault ...

Fix this by accounting for vmalloc possibility.
