Use a processor-specific interrupt frame during context switches in case the executing thread is longer executes on the processor and the heir thread is about to start execution. During this period we must not use a thread stack for interrupt processing. Update #2809.
This is the README file for libcpu. This directory contains reusable libraries which are CPU dependent but not target board dependent. For example, the PowerPC has an on CPU decrementer register which may be used by all PowerPC BSP's for the Clock and Timer Drivers. Other examples include the caching support for the m68k CPU models and MIPS CPU model exception vectoring routines. This level of support will make it easier for others developing embedded applications on a given CPU.
