Well this is awkward.

Your um-clean-up-vm-flagsh.patch deleted arch/um/sys-x86_64/mem.c.

There's not really any appropriate .c file in arch/um/sys-x86_64 for
these functions so I changed the patch to reinstate mem.c.

Then I changed my maind and dropped it ;) Hopefully none of the other
patches depended on this one.

Then I looked at um-implement-a-x86_64-vdso.patch, got nervous and
undropped um-set-__have_arch_gate_area-for-x86_64.patch.
