This helps with plugging some race conditions with cpu hotplug (IPI-race) and other things. More details in the respective patches. Andrew: Please consider for -mm for some exposure The series has 2 patches. - Change bigsmp to use flat physical mode instead of logical cluster - If hotplug is enabled choose bigsmp mode by default. Both the above are default behaviour for x86_64 builds. I have tested on some dual core boxes, it will help more testing if people who use bigsmp can give feedback would be great. Cheers, ashok
