> Build fix for sparc below, I'm playing with this now. I get various assertion failures and crashes during make -j128 kernel builds on my sparc64 box: ==================== perf: Segmentation fault -------- backtrace -------- /lib/sparc-linux-gnu/libc.so.6(+0x38918)[0xf7264918] ./perf(thread__set_namespaces+0x30)[0x10b2f0] ./perf(machine__process_namespaces_event+0x134)[0xfad54] ./perf[0x517b8] ./perf(queued_events__flush+0xc8)[0x109288] ./perf[0x5133c] /lib/sparc-linux-gnu/libpthread.so.0(+0x6714)[0xf7c7e714] /lib/sparc-linux-gnu/libc.so.6(+0xf70b4)[0xf73230b4] /lib/sparc-linux-gnu/libpthread.so.0(+0x6a84)[0xf7c7ea84] davem@patience:~/src/GIT/sparc/tools/perf$ ==================== and: ==================== perf: /home/davem/src/GIT/sparc/tools/include/linux/refcount.h:131: refcount_sub_and_test: Assertion `!(new > val)' failed. ==================== I don't have a lot of time to try and debug this, but let me know if you want any fixes tested. I did look at the changes and I like what you're trying to do.
