bk bug? 3.0 in 2.0

[David Becker <becker@cs.duke.edu>]

I did cold clone just now of 2.0
   bk clone bk://xen.bkbits.net/xen-2.0.bk

and the xen/Makefile says:
    # This is the correct place to edit the build version.
    # All other places this is stored (eg. compile.h) should be
    # autogenerated.
    export XEN_VERSION       = 3
    export XEN_SUBVERSION    = 0
    export XEN_EXTRAVERSION  = "-devel"

That seems .. wrong?


Also 2.4.28-xen0 did not build.  Many files fail with this error:
xen-2.0.bk/linux-2.4.28-xen0/include/asm/timex.h:10:21: asm/msr.h: No such file or directory

The 2.6.9-xen0 kernel built fine.

Feature request:  add a help target to the top Makefile to print out the
list of valid targets (as is done in the main linux Makefile).



Here is a full error from the 2.4.28 build (its not just ebtables; other
files fail too):
