Author: mav Date: Sun Jul 17 12:45:58 2016 New Revision: 302947 URL: https://svnweb.freebsd.org/changeset/base/302947 Log: In AHCI_IRQ_MODE_AFTER mode do not clear interrupts below. This is probably a NOP change since IS register is not activery used for interrupts below the shared, but it looked odd to clear interrupts we did not handle.
