Those are left presumably from aborted ccache(1) compilations:
arch/x86/kernel/.tmp_io_apic_64.o.T5veul
arch/x86/kvm/.tmp_x86.o.SZWn69
arch/x86/mm/.tmp_pgtable.o.sL1LTf
drivers/ieee1394/.tmp_ieee1394_transactions.o.bUj6o1
drivers/infiniband/hw/mlx4/.tmp_main.o.vy0ep6
BTW, with git there is nice way to check for such nuisainces:
make mrproper
git-ls-files -o
should give empty output.
