There were no critical objections so this patch has been merged to the 2.6.21 uprev branch. The i386.patch has been removed, and replaced by i386-hw_breakpoints.patch and x86_64-hw_breakpoints.patch. The HW breakpoints work on SMP and UP systems at this point if you use gdb 6.6 or a gdb which supports the Z packets correctly for HW breakpoints. The HW breakpoint code was cleaned up in the core-lite.patch so as to use the kgdb_ops call backs if an arch implements hw breakpoints. At this point if someone would like to clean up the sw breakpoint references I'll gladly merge it, else this clean up will wait for the time being. Thanks, Jason.
