We initialize boot-time pagesets with setup_pageset(), which sets high and

We can remove this wrapper if we just set these values for all pagesets in
pageset_init(). Non-boot pagesets then subsequently update them to the proper
values.
No functional change.

Thanks!
Btw. where do we initialize pcp->count? I thought that pcp allocator
zeroes out the allocated memory but alloc_percpu is GFP_KERNEL like.
pageset_init() does:
memset(p, 0, sizeof(*p))
