Right, I split it up into two.

Sure, I just removed it now.

That was in no way my intention.
In contrary, I wanted to see if other platforms are affected by the same bug without knowing.
Do you by any chance know if it broke some of the existing platforms?
If yes, that would be valuable info...

Just in case people want to know what this is all about:
On parisc I found __ARCH_SI_PREAMBLE_SIZE to have a wrong value in 64bit kernel builds.
Patch which fixes it is here:
https://patchwork.kernel.org/patch/7994821/

To prevent other (existing and future) architectures to run into the same
problem I wanted to test this patch via linux-next and inform them:
http://git.kernel.org/cgit/linux/kernel/git/deller/parisc-linux.git/commit/?h=test__ARCH_SI_PREAMBLE_SIZE
