Description
In the Linux kernel, the following vulnerability has been resolved: net: ipa: fix GENERIC_CMD register field masks for IPA v5.0+ Fix the field masks to match the hardware layout documented in downstream GSI (GSI_V3_0_EE_n_GSI_EE_GENERIC_CMD_*). Notably this fixes a WARN I was seeing when I tried to send "stop" to the MPSS remoteproc while IPA was up.
