Let's allow page-alignment in general for per-cpu data (wanted by Xen, and Ingo suggested KVM as well). Because larger alignments can use more room, we increase the max per-cpu memory to 64k rather than 32k: it's getting a little tight.

* It is VERY DANGEROUS to fiddle around with the symbols in this

|
|
* that are used are actually named here, otherwise the linker will
|
|
* put them at the end, where the init stuff is which is FREED after
|
|
* the kernel has booted.
