05d405dade Add support for more open flags that have a native equivalent 
(O_NONBLOCK, O_DIRECT and O_NOFOLLOW).
Translate native EFTYPE error (missing on Linux) to expected ELOOP;
when opening symlinks with flag O_NOFOLLOW.

a good idea; but not proven harmful.

c1cf2f47fb A specially-crafted binary could easily control a kernel array index. 
Add some checks to ensure that nothing will be read outside the allocated
area. Rewrite the code so that we don't need to allocate the whole section.

b9df3e93ac Remove all references to MDL_USEDFPU and deferred fpu initialisation. 
The cost of zeroing the save area on exec is minimal.
This stops the FP registers of a random process being used the first
  time an lwp uses the fpu.
sendsig_siginfo() and get_mcontext() now unconditionally copy the FP
registers.
I'll remove the double-copy for signal handlers soon.
get_mcontext() might have been leaking kernel memory to userspace - and
  may still do so if i386_use_fxsave is false (short copies).

519a61193d Convert the amd64 build to use x86/cpu_extended_state.h so that the fpu 
definitions match those of i386.
Mostly just structure and field renames, in addition:
1) process_xmm_to_s87() and process_s87_to_xmm() moved into
   x86/convert_xmm_s87.c so they can be used by amd64's netbsd32 code.
2) The linux signal code simplified to use a structure copy for ths fxsave
   data - it matches the hardware definition and won't change.
