The Linux kernel is having to remove support for NWFPE and VFP emulation code due to a licensing conflict. Removing NWFPE and VFP from the kernel will effectively render older ARM hardware on Linux useless until a solution is determined.
Russell King, the maintainer of the ARM code for the Linux kernel, announced this removal on the linux-arm-kernel mailing list. The NWFPE (NetWinder Floating Point Emulator) and VFP (Vector Floating Point) code is for emulating floating-point operations within the kernel. While this code is critical to ARM hardware without hardware floating-point support, the code needs to be dropped due to a licensing conflict.
