7f33b09c65 RISC-V: Linux ABI 
Linux-specific code that is required for maintaining ABI compatibility.
This doesn't contain the actual system call interface, that is split out
in order to avoid having a patch that's too big.

d1c09b2471 RISC-V: Atomic and Locking Routines 
This patch implements various atomic and locking routines on RISC-V.  We
mandate the A extension on Linux-capable RISC-V systems, so this can
rely on always having the various atomic instructions availiable.
