usercopy: Restrict non-usercopy caches to size 0
With all known usercopied cache whitelists now defined in the
kernel, switch the default usercopy region of kmem_cache_create()
to size 0. Any new caches with usercopy regions will now need to use
kmem_cache_create_usercopy() instead of kmem_cache_create().
This patch is modified from Brad Spengler/PaX Team's PAX_USERCOPY
whitelisting code in the last public patch of grsecurity/PaX based on my
understanding of the code. Changes or omissions from the original code are
mine and don't reflect the original grsecurity/PaX code.
