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.

A flaw was found in the Linux kernel's Integrated Packet Accelerator (IPA) driver. Incorrectly configured register field masks for IPA version 5.0 and newer could lead to system instability. This issue may manifest as a warning when attempting to send commands to the MPSS remoteproc, potentially resulting in a denial of service where the system fails to operate as intended.
