Description

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

iommu/riscv: Serialize command queue publishing

Serialize command queue publishing so software producer state advances only after a command is written and the hardware tail is updated. Wait for hardware consumption outside the queue lock when the command queue is full so other CPUs are not blocked behind a long poll.
