Module Name:    src
Committed By:   matt
Date:           Thu Feb 17 19:27:13 UTC 2011

Modified Files:
        src/sys/kern: kern_kthread.c
        src/sys/uvm: uvm_extern.h uvm_glue.c

Log Message:
Add support for cpu-specific uarea allocation routines.  Allows different
allocation for user and system lwps.  MIPS will use this to map uareas of
system lwp used direct-mapped addresses (to reduce the overhead of
switching to kernel threads).  ibm4xx could use to map uareas via direct
mapped addresses and avoid the problem of having the kernel stack not in
the TLB.
