The good news is that I have a 2.6.37 kernel + your patches booting and it has been running for about an hour on sparc64/Sun Fire V120. I did a bit of poking around in /debug and turned on/off a bit of tracing and nothing broke. I did have a few problems applying your patch series. Your diffs have semicolons at the end of a couple of the macros that don't appear in the mainline 2.6.37. One was circa line 174 of include/linux/tracepoint.h but I don't have the other to hand at the moment and I don't have much time before I need to go out. I'm also getting a lot of Kernel unaligned access errors from the kernel. I don't know if they are related to this or not and this is the first time that I personally have got 2.6.37 to boot on sparc64. The messages that I am getting seem to be repeats of [ 4376.807811] Kernel unaligned access at TPC[456e94] try_to_wake_up+0x58/0xec [ 4376.807908] Kernel unaligned access at TPC[75541c] schedule+0x454/0x660 [ 4376.808044] Kernel unaligned access at TPC[75541c] schedule+0x454/0x660 [ 4376.808871] Kernel unaligned access at TPC[456e94] try_to_wake_up+0x58/0xec [ 4376.808965] Kernel unaligned access at TPC[75541c] schedule+0x454/0x660 [ 4381.813354] log_unaligned: 337 callbacks suppressed I have to go out now but will be around later/over the weekend.
