From: Chuck Lever <chuck.lever@oracle.com>

This series implements the generation of "maxsize" values for each
XDR data type defined in a specification. These are emitted as C
pre-processor macros, following the lead of existing XDR functions
in the kernel. The macros are added to the header file containing
C type definitions.

This facility takes xdrgen a step closer to the generation of all
XDR code needed for each RPC protocol implementation in the kernel.

Changes since v1:
- Resend including all 16 patches (d'oh)

Chuck Lever (16):
  xdrgen: Refactor transformer arms
  xdrgen: Track constant values
  xdrgen: Keep track of on-the-wire data type widths
  xdrgen: XDR widths for enum types
  xdrgen: XDR width for fixed-length opaque
  xdrgen: XDR width for variable-length opaque
  xdrgen: XDR width for a string
  xdrgen: XDR width for fixed-length array
  xdrgen: XDR width for variable-length array
  xdrgen: XDR width for optional_data type
  xdrgen: XDR width for typedef
  xdrgen: XDR width for struct types
  xdrgen: XDR width for pointer types
  xdrgen: XDR width for union types
  xdrgen: Add generator code for XDR width macros
  xdrgen: emit maxsize macros
