2015-03-31enclosure: fix WARN_ON removing an adapter in multi-path devicesJames Bottomley1-5/+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.

2015-03-16misc: sram: switch to ioremap_wc from ioremapAbhilash Kesavan1-3/+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.

2015-02-06cxl: Add missing return statement after handling AFU errrorIan Munsie1-0/+1
We were missing a return statement in the PSL interrupt handler in the case of an AFU error, which would trigger an "Unhandled CXL PSL IRQ" warning. We do actually handle these type of errors (by notifying userspace), so add the missing return IRQ_HANDLED so we don't throw unecessary warnings.
