2015-03-24staging: octeon-usb: eliminate 64-bit register access wrappersAaro Koskinen1-75/+33
Eliminate 64-bit register access wrappers. Since we don't implement register-level debugging outputs, these are useless. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2014-12-15Merge tag 'staging-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/stagingLinus Torvalds1-28/+41
Pull staging driver updates from Greg KH: "Here's the big staging tree pull request for 3.19-rc1. We continued to delete more lines than were added, always a good thing, but not at a huge rate this release, only about 70k lines removed overall mostly from removing the horrid bcm driver. Lots of normal staging driver cleanups and fixes all over the place, well over a thousand of them, the shortlog shows all the horrid details. The "contentious" thing here is the movement of the Android binder code out of staging into the "real" part of the kernel. This is code that has been stable for a few years now and is working as-is in the tens of millions of devices with no issues. Yes, the code is horrid, and the userspace api leaves a lot to be desired, but it's not going to change due to legacy issues that we have no control over. Because so many devices and companies rely on this, and the code is stable, might as well promote it out of staging. This was all discussed at the Linux Plumbers conference, and everyone participating agreed that this was the best way forward. There is work happening to replace the binder code with something new that is happening right now, but I don't expect to see the results of that work for another year at the earliest. If that ever happens, and Android switches over to it, I'll gladly remove this version. As for maintainers, I'll be glad to maintain this code, I've been doing it for the past few years with no problems. I'll send a MAINTAINERS entry for it before 3.19-final is out, still need to talk to the Google developers about if they are willing to help with it or not, last I checked they were, which was good.

2014-03-20staging: octeon-usb: prevent memory corruptionAaro Koskinen1-0/+108
octeon-hcd will crash the kernel when SLOB is used. This usually happens after the 18-byte control transfer when a device descriptor is read. The DMA engine is always transfering full 32-bit words and if the transfer is shorter, some random garbage appears after the buffer. The problem is not visible with SLUB since it rounds up the allocations to word boundary, and the extra bytes will go undetected. Fix by providing quirk functions for DMA map/unmap that allocate a bigger temporary buffer when necessary. Tested by booting EdgeRouter Lite to USB stick root file system with SLAB, SLOB and SLUB kernels.
