      x86-32: Start out cr0 clean, disable paging before modifying cr3/4 · 021ef050

        5a5a51db x86-32: Start out eflags and cr4 clean
      
      ... made x86-32 match x86-64 in that we initialize %eflags and %cr4
      from scratch.  This broke OLPC XO-1.5, because the XO enters the
      kernel with paging enabled, which the kernel doesn't expect.
      
      Since we no longer support 386 (the source of most of the variability
      in %cr0 configuration), we can simply match further x86-64 and
      initialize %cr0 to a fixed value -- the one variable part remaining in
      %cr0 is for FPU control, but all that is handled later on in
      initialization; in particular, configuring %cr0 as if the FPU is
      present until proven otherwise is correct and necessary for the probe
      to work.
      
      To deal with the XO case sanely, explicitly disable paging in %cr0
      before we muck with %cr3, %cr4 or EFER -- those operations are
      inherently unsafe with paging enabled.
      
      NOTE: There is still a lot of 386-related junk in head_32.S which we
      can and should get rid of, however, this is intended as a minimal fix
      whereas the cleanup can be deferred to the next merge window.
