[PATCH v2 0/2] Consolidate redundant register/stack access code

[David Long]

From: "David A. Long" <dave.long@xxxxxxxxxx>

Move duplicate and functionally equivalent code for accessing registers
and stack (CONFIG_HAVE_REGS_AND_STACK_ACCESS_API) from arch subdirs into
common kernel files.

Changes since v1:
    Move the REG_OFFSET_NAME and REG_OFFSET_END macros to architecture-
    independent include file. Change their name from REG_* to REGS_* for
    consistency.

Note: Help regression testing s390, hexagon, and sh would be appreciated.
      Powerpc builds but I have not verified the functionality.

David A. Long (2):
  Move the pt_regs_offset struct definition from arch to common include
    file
  Consolidate redundant register/stack access code
