into a common file for each OS.
The merge is performed in the following steps:
-1. Construct the set of common code that is idential in all architecture-specific files.
+1. Construct the set of common code that is identical in all architecture-specific files.
2. Write this common code to the merged file.
3. Remove the common code from all architecture-specific files.

+// RISC-V extension discovery code for Linux. The approach here is to first try the riscv_hwprobe
+// syscall falling back to HWCAP to check for the C extension if riscv_hwprobe is not available.
+//
+// A note on detection of the Vector extension using HWCAP.
+//
+// Support for the Vector extension version 1.0 was added to the Linux kernel in release 6.5.
+// Support for the riscv_hwprobe syscall was added in 6.4. It follows that if the riscv_hwprobe
+// syscall is not available then neither is the Vector extension (which needs kernel support).
+// The riscv_hwprobe syscall should then be all we need to detect the Vector extension.
+// However, some RISC-V board manufacturers ship boards with an older kernel on top of which
+// they have back-ported various versions of the Vector extension patches but not the riscv_hwprobe
+// patches. These kernels advertise support for the Vector extension using HWCAP. Falling
+// back to HWCAP to detect the Vector extension, if riscv_hwprobe is not available, or simply not
+// bothering with riscv_hwprobe at all and just using HWCAP may then seem like an attractive option.
+//
+// Unfortunately, simply checking the 'V' bit in AT_HWCAP will not work as this bit is used by
+// RISC-V board and cloud instance providers to mean different things. The Lichee Pi 4A board
+// and the Scaleway RV1 cloud instances use the 'V' bit to advertise their support for the unratified
+// 0.7.1 version of the Vector Specification. The Banana Pi BPI-F3 and the CanMV-K230 board use
+// it to advertise support for 1.0 of the Vector extension. Versions 0.7.1 and 1.0 of the Vector
+// extension are binary incompatible. HWCAP can then not be used in isolation to populate the
+// HasV field as this field indicates that the underlying CPU is compatible with RVV 1.0.
+//
+// There is a way at runtime to distinguish between versions 0.7.1 and 1.0 of the Vector
+// specification by issuing a RVV 1.0 vsetvli instruction and checking the vill bit of the vtype
+// register. This check would allow us to safely detect version 1.0 of the Vector extension
+// with HWCAP, if riscv_hwprobe were not available. However, the check cannot
+// be added until the assembler supports the Vector instructions.
+//
+// Note the riscv_hwprobe syscall does not suffer from these ambiguities by design as all of the
+// extensions it advertises support for are explicitly versioned. It's also worth noting that
+// the riscv_hwprobe syscall is the only way to detect multi-letter RISC-V extensions, e.g., Zba.
+// These cannot be detected using HWCAP and so riscv_hwprobe must be used to detect the majority
+// of RISC-V extensions.
+//
+// Please see https://docs.kernel.org/arch/riscv/hwprobe.html for more information.
