Alan Cox 49bfa624ac Eliminate the arena parameter to kmem_free(). Implicitly this corrects an ... error in the function hypercall_memfree(), where the wrong arena was being passed to kmem_free(). Introduce a per-page flag, VPO_KMEM_EXEC, to mark physical pages that are mapped in kmem with execute permissions. Use this flag to determine which arena the kmem virtual addresses are returned to. Eliminate UMA_SLAB_KRWX. The introduction of VPO_KMEM_EXEC makes it redundant. Update the nearby comment for UMA_SLAB_KERNEL.
