I'll end up googling this, but I'm going to go ahead and ask anyway. How do you cross compile for ARM? How can I be sure I am building against my phone's kernel version?
I didn't see anything really helpful by doing dmesg.... except that I get the message: PVR_K:(Warning): PVRSRVFreeDeviceMemBW: mappings are open in other processes, deferring free! [571, drviers/gpu/pvr/bridged_pvr_bridge.c] It still kept displaying even after turning phone on and off.
