Hi,
Currently, there's no way to make a data part of both the init section
and the bss section. Therefore uninitialized init data consume useless
space in the vmlinux image.
Most of these data can be listed by:
$ git grep -E "__initdata([^=]*| ?= ?0);" -- *.c
This short patchset is an attempt to make these init data part of the
bss section (done by patch #1) and therefore decreases the size of the
vmlinux image.
For now, only MIPS architecture handles this new section, this is done
by patch #2. It's only a start and should be enough for discussion.
Please consider,
Franck
