| * misc: sram: switch to ioremap_wc from ioremapAbhilash Kesavan2015-03-161-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the SRAM allocator returns device memory via ioremap. This causes issues on ARM64 when the internal SoC SRAM allocated by the generic sram driver is used for audio playback. The destination buffer address (which is ioremapped SRAM) is not 64-bit aligned for certain streams (e.g. 44.1k sampling rate). In such cases we get unhandled alignment faults. Use ioremap_wc in place of ioremap which gives us normal non-cacheable memory instead of device memory.

| * | enclosure: fix WARN_ON removing an adapter in multi-path devicesJames Bottomley2015-03-311-5/+6
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have peculiar problems with multi-path and enclosures: physically, we know each bay can only be occupied by a single disk device. However in multi-path, it appears we have many (because each path to the device appears in Linux as a different kernel device). We try to fix this by only having the last seen device show up in the bay. Sysfs gets very annoyed if we try to manipulate links when the kobject sysfs directory (kobj.sd) doesn't exist and drops a huge WARN_ON which most users panic and report an oops for. This happens on a few path removal situations and IBM reports seeing it when one of their multi-path adapters is removed. Add a check to enclosure device removal for the existence the sysfs directory containing both the forward and back links so that the remnants (if any) get removed in either direction but no scary warnings are dumped.

| * ti-st: clean up data types (fix harmless memory corruption)Dan Carpenter2015-02-041-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The big issue here is: of_property_read_u32(np, "flow_cntrl", (u32 *)&dt_pdata->flow_cntrl); "->flow_cntrl" is a char so when we write a 32 bit number to it then it corrupts past the end of the char. It's probably hard to notice because the struct has padding so the code works on little endian systems. But on a big endian system the code would fail and on a 64 bit, big endian systems then "nshutdown_gpio" and "baud_rate" would be buggy as well.
