Hi Andrew,

[patch 1/3] Use DATA_DATA in CRIS

[Mathieu Desnoyers]

[-- Attachment #1: use-data-data-in-cris.patch --]
[-- Type: text/plain, Size: 1692 bytes --]

Newer asm-generic/vmlinux.lds.h provides a DATA_DATA macro which defines the
content of what is normally referred to by *(.data). It permits adding more
"subsections" (declared by gcc with the section attribute or in assembly), which
will be linked in the .data section.
