CVS commit: src/sys/uvm

[Matthias Drochner <drochner%netbsd.org@localhost>]

Module Name:    src
Committed By:   drochner
Date:           Wed Jul  5 14:26:42 UTC 2006

Modified Files:
        src/sys/uvm: uvm_extern.h uvm_km.c

Log Message:
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.
