The patch titled rapidio: modify mport ID assignment has been removed from the -mm tree. Its filename was rapidio-modify-mport-id-assignment.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: rapidio: modify mport ID assignment From: Alexandre Bounine <alexandre.bounine@xxxxxxx> Changes mport ID and host destination ID assignment to implement unified method common to all mport drivers. Makes "riohdid=" kernel command line parameter common for all architectures with support for more that one host destination ID assignment.
