Is this exactly true?  What about generating SFrame data in the linker
from the existing DWARF EH data?

This would not work automatically for kernel modules because generating
SFrame data should not be the default for relocatable links.  Maybe an
--sframe-index option for ld or objcopy would be acceptable?  Kernel
modules do not have the usual post-processing problems because they are
relocatable, and their build is typically controlled by the kernel's
build system.

Thanks,
Florian
