Enable ALIGN #undef for drivers/net/defxx.c
PATCH 1/1 Enable ALIGN #undef for drivers/net/defxx.c
The following patch #undef's the variable ALIGN in include/linux/cache.h so that drivers/net/defxx.c can use the same variable. Patch has been tested and defxx.c compiles. Please apply.

The following patch #undef's the variable ALIGN in
include/linux/cache.hso thatdrivers/net/defxx.ccan use the same variable. Patch has been tested anddefxx.ccompiles. Please apply.
But they're identical. It would be better to formalise the kernel-wideness of ALIGN() and just use it in defxx?

I agree. At least the bug has a chance of getting fixed.
