Commit 3ab83521378268044a448113c6aa9a9e245f4d2f (kexec jump)
causes the following build error on sh:
<-- snip -->
...
CC kernel/kexec.o
{standard input}: Assembler messages:
{standard input}:1518: Error: offset to unaligned destination
make[2]: *** [kernel/kexec.o] Error 1
<-- snip -->
If I understand the assembler correctly it fails at
include/asm-sh/kexec.h:59
