[PATCH 0/5] Add and use sizeof_member macro to bring uniformity

[Pankaj Bharadiya]

This topic has been discussed on the kernel hardening mailing list [1]
few months back. Thanks to Shyam for initiating work on this.

Its been concluded on how the patch series should be but there was
no further progress and this work is still pending (Pardon me if I 
missed something here).

At present, we have 3 different macros which serve the same purpose
of finding the size of a member of a structure:
  - SIZEOF_FIELD
  - FIELD_SIZEOF
  - sizeof_field

To bring uniformity in entire kernel source tree, this patch series -
  - adds the new sizeof_member macro
  - does scripted replacement of above 3 macros where used with newly
    introduced sizeof_member macro
  - removes definitions of SIZEOF_FIELD, FIELD_SIZEOF, sizeof_field

This series aims to fix the issue based on given comments in [1].

  linux/kernel.h: Add sizeof_member macro
  treewide: Use sizeof_member macro
  MIPS: OCTEON: use sizeof_member macro instead of SIZEOF_FIELD
  linux/kernel.h: Remove FIELD_SIZEOF macro
  stddef.h: Remove sizeof_field macro
