Add a DEBUG config setting which turns on all (most) of the debugging under platforms/pseries. To have this take effect we need to remove all the #undef DEBUG's, in various files. We leave the #undef DEBUG in platforms/pseries/lpar.c, as this enables debugging printks from the low-level hash table routines, and tends to make your system unusable. If you want those enabled you still have to turn them on by hand. Also some of the RAS code has a DEBUG block which causes a functional change, so I've keyed this off a different (non-existant) debug #define. This is only enabled if you have PPC_EARLY_DEBUG enabled also. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
