We have a patch for that in our repository.
Martin will send that fix with the next bunch of fixes.
Subject: [PATCH] Fix compile error on 31bit without preemption
From: Christian Borntraeger <[email protected]>
Commit b8e7a54cd06b0b0174029ef3a7f5a1415a2c28f2 introduced a compile
error if CONFIG_PREEMPT is not set:
arch/s390/kernel/built-in.o: In function `cleanup_io_leave_insn':
/space/kvm/arch/s390/kernel/entry.S:(.text+0xbfce): undefined reference to `preempt_schedule_irq'
This patch hides preempt_schedule_irq if CONFIG_PREEMPT is not set.
