Patch pm-acpi-hibernation-utilize-hardware-signature.patch in the 07/11 mmotm
causes a link error:
LD .tmp_vmlinux1
arch/x86/kernel/built-in.o: In function `acpi_sleep_setup':
sleep.c:(.init.text+0x6854): undefined reference to `acpi_no_s4_hw_signature'
Not at all surprising, since the patch doesn't actually include a body
for the function, only references. Did a (hopefully) previous patch that
added the body get lost along the way?
