The patch titled memory_accessor: new interface for reading/writing persistent memory has been removed from the -mm tree. Its filename was memory_accessor-new-interface-for-reading-writing-persistent-memory.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: memory_accessor: new interface for reading/writing persistent memory From: Kevin Hilman <khilman@xxxxxxxxxxxxxxxxxxx> Add an interface by which other kernel code can read/write persistent memory such as I2C or SPI EEPROMs, or devices which provide NVRAM. Use cases include storage of board-specific configuration data like Ethernet addresses and sensor calibrations. Original idea, review and improvement suggestions by David Brownell.
