[PATCH 01/10 net-next v3] ipv6: convert CONFIG_IPV6 to built-in only and clean up Kconfigs

[PATCH 01/10 net-next v3] ipv6: convert CONFIG_IPV6 to built-in only and clean up Kconfigs

[Fernando Fernandez Mancera]

Maintaining a modular IPv6 stack offers image size savings for specific
setups, this benefit is outweighed by the architectural burden it
imposes on the subsystems on implementation and maintenance. Therefore,
drop it.

Change CONFIG_IPV6 from tristate to bool. Remove all Kconfig
dependencies across the tree that explicitly checked for IPV6=m. In
addition, remove MODULE_DESCRIPTION(), MODULE_ALIAS(), MODULE_AUTHOR()
and MODULE_LICENSE().

This is also replacing module_init() by device_initcall(). It is not
possible to use fs_initcall() as IPv4 does because that creates a race
condition on IPv6 addrconf.

Finally, modify the default configs from CONFIG_IPV6=m to CONFIG_IPV6=y
except for m68k as according to the bloat-o-meter the image is
increasing by 330KB~ and that isn't acceptable. Instead, disable IPv6 on
this architecture by default. This is aligned with m68k RAM requirements
and recommendations [1].

[PATCH 05/10 net-next v3] drivers: net: drop ipv6_stub usage and use direct function calls

[Fernando Fernandez Mancera]

As IPv6 is built-in only, the ipv6_stub infrastructure is no longer
necessary.

Convert all drivers currently utilizing ipv6_stub to make direct
function calls. The fallback functions introduced previously will
prevent linkage errors when CONFIG_IPV6 is disabled.

That's a Kconfig/defconfig only patch, so build system. You cannot test
it in a meaning of testing code. Building code is not testing.

You removed important parts of Ack. It was not provided like that.

I do not agree. This isn't a Kconfig/defconfig only patch. It is taking 
down some module logic like changing module_init() to device_initcall(). 
Indeed, on v1, this patch was introducing a regression as it was using 
fs_initcall().

Sorry about that. I will make sure to include the # arm64 on the next 
revision.

Fernando.

Indeed, hiding among Kconfigs there is one C file. I missed that, it's fine.
