drochner ef8848c74a Introduce a UVM_KMF_EXEC flag for uvm_km_alloc() which enforces an
executable mapping. Up to now, only R+W was requested from pmap_kenter_pa.
On most CPUs, we get an executable mapping anyway, due to lack of
hardware support or due to lazyness in the pmap implementation. Only
alpha does obey VM_PROT_EXECUTE, afaics.
