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

VMCI: Use threaded irqs instead of tasklets

The vmci_dispatch_dgs() tasklet function calls vmci_read_data()
which uses wait_event() resulting in invalid sleep in an atomic
context (and therefore potentially in a deadlock).

Use threaded irqs to fix this issue and completely remove usage
of tasklets.
