Esteemed kernel hackers, To follow is my fifth pass at MIPS watch register support. The differences from the previous version: http://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=48C8ADEF.9020305%40avtrex.com * Respun against linux-queue. * Clear the WP bit in cause register on watch exception. The corresponding GDB patch is here: http://sourceware.org/ml/gdb-patches/2008-09/msg00230.html Six patches to follow. Thanks David Daney
