Date: Sat, 18 Jul 2015 18:04:21 +0000 From: "Dixit, Ashutosh" <ashutosh.dixit@...el.com> To: 'Toshi Kani' <toshi.kani@...com>, "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> CC: "Dutt, Sudeep" <sudeep.dutt@...el.com>, "Rao, Nikhil" <nikhil.rao@...el.com>, "Williams, Dan J" <dan.j.williams@...el.com> Subject: Regression in v4.2-rc1: vmalloc_to_page with ioremap 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.
