Intel-SIG: commit 42a1b738 dmaengine: idxd: Separate user and kernel pasid enabling.
Incremental backporting patches for DSA/IAA on Intel Xeon platform.

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

The idxd driver always gated the pasid enabling under a single knob and
this assumption is incorrect. The pasid used for kernel operation can be
independently toggled and has no dependency on the user pasid (and vice
versa). Split the two so they are independent "enabled" flags.
