Description:
Arch user Graysky has a rather useful patch that allows for easy cpu optimizations for the linux kernel 3.15+;
considering the default linux PKGBUILD seems to encourage customization of your kernel this seems a very valid
addition to the default setup. Applying this patch to the testing/linux folder changes the config, config.x86_64,
and PKGBUILD files but makes no changes to the normal build process without setting a value to _cpu_type; as such
it would make no changes to the default repo linux package without user intervention.


Additional info:
* package version(s): 4.2-4
   cpu_optimizations.patch (5 KiB)
This task depends upon

Does't seem like anyone wants to do this... and I can understand why, because we don't patch the kernel to make it easier for users to customize -- we merely arrange what *we* do, to make it easier to modify.

It is simple enough for anyone who actually wants it, to simply add it to source=() and let make olddefconfig or nconfig if you modify that in, guide you through setting the relevant options.

I don't see how this gcc patch makes it any easier for people to do that. Less time-consuming, yes. But not even by that much. And it is something that would have to be tracked and kept up-to-date even though it would definitively never ever be used by the kernel packagers.
