[PATCHSET 0/5] BUILD_BUG_ON: error on none-const expressions

From: Boaz Harrosh

Submitted a patchset to fix BUILD_BUG_ON to no longer let through
none compile-time constant expressions. This was debated a few
times on LKML. The final solution is as proposed by Rusty Russell,
which produces all expected results in my tests.
[see: http://www.spinics.net/lists/kernel/msg772904.html]

[PATCH 1/5] debug, x86: move BUILD_BUG_ON() ARRAY_SIZE and __FUNCTION__
Ingo this is your patch. Please verify?

[PATCH 2/5] net/niu: Fix none-const BUILD_BUG_ON usage
[PATCH 3/5] virtio: Fix none-const BUILD_BUG_ON usage
[PATCH 4/5] rt2x00: Compiler warning unmasked by fix of BUILD_BUG_ON
These three need maintainers approval. I hope I did not forget
anyone

[PATCH 5/5] debug: BUILD_BUG_ON: error on none-const expressions
Finally after all call sites are fixed this can go in.
(Rusty this one is From: you)

I have only compiled ARCH=x86 (64/32) allmodconfig. So this might
break on other ARCHs. It should spend a night in Linux-Next to expose
these places.

Thanks
Boaz
