Intel-SIG: commit 5b0c68c4 dmaengine: idxd: support reporting of halt interrupt.
Incremental backporting patches for DSA/IAA on Intel Xeon platform.

--------------------------------

Unmask the halt error interrupt so it gets reported to the interrupt
handler. When halt state interrupt is received, quiesce the kernel
WQs and unmap the portals to stop submission.
