Hmm.
SUBARCH is used by arch/x86/um/Kconfig
to choose 64BIT.

Maybe, do we need $(SUBSRCARCH) ?


(In hindsight, HOST_ARCH and HOST_SRCARCH
might be clearer, though...)

Looks like it.  I'll give it a spin and will resend (including the
folded PREEMPT_CODE fix).

What do you think of the patch below?  This reuses the HEADER_ARCH
variable that uml already needs to setup anyway:
