Ingo Molnar spoke to changes for the x86 architecture, 'there are 763 commits in x86.git so far, from more than 90 contributors, so it would be difficult to mention and credit every contribution in this mail.'

"'Continued, intense arch/x86 unification and cleanup work by lots of people; FIFO ticket spinlocks for better spinlock scalability; 'regset' generalizations - the most important step towards utrace support (==next-gen ptrace); support for more than 255 CPUs [up to 4096 - in theory up to 65535]; almost complete 64-bit paravirt guest support; KGDB support on x86, finally...!'"
