+@li Linux "ISR" thread stack size not correct (Fixed by Till Straumann)
+@li Linux: Previous versions expected Linux kernel modules to leave gaps for un-mappable PCI BARs (I/O Ports).
+    However, most existing kernel modules don't do this.  Add a flag to devPCIToLocalAddr() to specify
+    how a device's kernel module does mapping.  The default is to map as in previous versions.
+    (New behavior by Till Straumann)
     See documentation of devPCIToLocalAddr().
