[Xen-devel] [PATCH v2 1/7] build: add debug menu to Kconfig

[Doug Goldstein <cardoe@xxxxxxxxxx>]

There are a number of debugging options for Xen so the idea is to have a
menu to group them all together. Enabling this menu item will also
disable NDEBUG which will result in more debug prints. This was
previously wired into the 'debug=y' command line option.
