 Log Message:
 Compute real/protected %sp/%esp offset in 'gdt_fixup' using all 32-bits.
 Allows the case of %ss being less than %cs to work.
 Also, completely save and restore the general-purpose registers we use.

It ought to be possible to initialise the gdt (etc) as compile time.
The addresses are always fixed.

  src/sys/kern: vfs_lookup.c
 
 Log Message:
 - lookup_once: when crossing a mount point, don't keep the parent vnode 
 locked.
   ie. don't lock a vnode while holding another vnode which belongs to a
   different filesystem.  otherwise we propagate slowness (or deadness) of a
   filesystem to another via vnode lock chain.
 - lookup_parsepath: don't alter vnode states.  let the caller do it instead.
 - add comments and assertions.
 
 Hi, this breaks the state-dp != ndp-ni_dvp invariant in at least 3
 places in vfs_lookup.c:

 Can you have a look?

i'll take a look later.  thanks.
