The vmlinux.lds.h knobs to emit the __jump_table section in the main kernel image takes care to align the section, but this doesn't help for the __jump_table section that gets emitted into modules. Fix the resulting lack of section alignment by explicitly specifying it in the assembler. Signed-off-by: David S.
