      [PATCH] i386: inline asm cleanup · 4bb0d3ec

      i386 Inline asm cleanup.  Use cr/dr accessor functions.
      
      Also, a potential bugfix.  Also, some CR accessors really should be volatile.
      Reads from CR0 (numeric state may change in an exception handler), writes to
      CR4 (flipping CR4.TSD) and reads from CR2 (page fault) prevent instruction
      re-ordering.  I did not add memory clobber to CR3 / CR4 / CR0 updates, as it
      was not there to begin with, and in no case should kernel memory be clobbered,
      except when doing a TLB flush, which already has memory clobber.
      
      I noticed that page invalidation does not have a memory clobber.  I can't find
      a bug as a result, but there is definitely a potential for a bug here:
      
      #define __flush_tlb_single(addr) \
      	__asm__ __volatile__("invlpg %0": :"m" (*(char *) addr))

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
