vmalloc_to_page with ioremap'd memory used to work correctly till v4.1. In v4.2-rc1 when ioremap is done using huge pages vmalloc_to_page on ioremap'd memory crashes. Are there plans to fix this?
An example of the use of vmalloc_to_page with ioremap is in the Intel MIC SCIF driver (drivers/misc/mic/scif/scif_nodeqp.c) which dma map's the ioremap'd range of one device to a second device.
