David van Moolenbroek 20054ae93f Kernel: separate userland ABI on kernel page
Currently, the userland ABI uses a single field ('user_sp') far
into the very large 'kinfo' structure on the shared kernel
information page.  This precludes us from modifying or getting
rid of 'kinfo' in the future without breaking userland.  This
patch adds a separate 'kuserinfo' structure to the kernel
information page, with only information that is part of the
userland ABI, in an extensible manner.  Userland now uses this
field if it is present, and falls back to the old field if not.
