Something is seriously wrong and should be fixed. for parisc:defconfig, FATAL: The relocation at __ex_table+0x634 references section "__ex_table" which is not executable, IOW the kernel will fault if it ever tries to jump to it. Something is seriously wrong and should be fixed. for score:allnoconfig, and FATAL: The relocation at __ex_table+0x8 references section "" which is not executable, IOW it is not possible for the kernel to fault at that address. Something is seriously wrong and should be fixed. for mn10300:defconfig. While I agree that those should get fixed (if they are real problems, especially the ones for parisc and mn10300), I don't think it is a good idea to fail the build because of it. Note that I did find the problem in the score build; that was a real bug. I don't know what may be wrong with the others.
