[PATCH] powerpc: Kill ppcdebug
The ancient ppcdebug/PPCDBG mechanism is now only used in two places. First, in the hash setup code, one of the bits allows the size of the hash table to be reduced by a factor of 8 - which would be better accomplished with a command line option for that purpose. The other was a bunch of bus walking related messages in the iSeries code, which would seem to be insufficient reason to keep the mechanism. This patch removes the last traces of this mechanism. Built and booted on iSeries and pSeries POWER5 LPAR (ARCH=powerpc). Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
