Linus, please pull the for_linus which contains a compilation fix for
building without the kernel config option CONFIG_HW_CONSOLE.
git://git.kernel.org/pub/scm/linux/kernel/git/jwessel/linux-2.6-kgdb.git for_lin
us
There are some other fixes brewing, but this is the only known
compilation problem and I know we would like to keep the tree fully
bisectable.
Thanks,
Jason.

console: Fix compilation regression

A regression of building without CONFIG_HW_CONSOLE was introduced with
commit b45cfba4e9005d64d419718e7ff7f7cab44c1994 (vt,console,kdb:
implement atomic console enter/leave functions).
ERROR: "con_debug_enter" [drivers/serial/kgdboc.ko] undefined!
ERROR: "vc_cons" [drivers/serial/kgdboc.ko] undefined!
ERROR: "fg_console" [drivers/serial/kgdboc.ko] undefined!
ERROR: "con_debug_leave" [drivers/serial/kgdboc.ko] undefined!
When there is no HW console the con_debug_enter and con_debug_leave
functions should have no code.
