[PATCH] tvec_bases too large for per-cpu data
With internal Xen-enabled kernels we see the kernel's static per-cpu data area exceed the limit of 32k on x86-64, and even native x86-64 kernels get fairly close to that limit. I generally question whether it is reasonable to have data structures several kb in size allocated as per-cpu data when the space there is rather limited. The biggest arch-independent consumer is tvec_bases (over 4k on 32-bit archs, over 8k on 64-bit ones), which now gets converted to use dynamically allocated memory instead.
