My newly rebased changes. There is no actual difference in the code since Davide's changes did not affect me.
The following changes since commit 495a723da7db40d18c933c0d9b979058b0d8ffa4: Use core_id_early() in kprof trace buffer print code (2015-12-08 16:32:42 -0500) are available in the git repository at: [email protected]:GanShun/akaros.git c0c444f9646147a530672546d5cdbaf28e357e70 for you to fetch changes up to c0c444f9646147a530672546d5cdbaf28e357e70: Swapped IPI sending to a full 64-bit write and APIC writes to msr regs.
