[RFC PATCH 0/1] Driver for ami305 magnetometer
This patch provides driver for two sw compatible 3 axis magnetometer chips (AMI305 / AK8974). Driver provides coordinates as polled input device. Chip can provide interrupt when the measurement result is ready, but this feature is not used. Instead, new measurement is started at polling event frequency. This meth... 12 Nov 2009 02:54

net/compat: fix dev_ifsioc emulation corner cases
From: Arnd Bergmann <arnd(a)arndb.de> Date: Wed, 11 Nov 2009 14:39:40 +0100 Handling for SIOCSHWTSTAMP is broken on architectures with a split user/kernel address space like s390, because it passes a real user pointer while using set_fs(KERNEL_DS). A similar problem might arise the next time somebody ... 11 Nov 2009 23:36
