CVS commit: src/sys/arch/amd64

["David Laight" <dsl%netbsd.org@localhost>]

Module Name:    src
Committed By:   dsl
Date:           Mon Dec 31 16:20:18 UTC 2012

Modified Files:
        src/sys/arch/amd64/amd64: fpu.c netbsd32_machdep.c
        src/sys/arch/amd64/include: fpu.h pcb.h

Log Message:
Move the two fields used to save some i387 state on the last fpu trap
  into their own sub-structure of the pcb (from 'struct savefpu').
They only (seem) to be used in some code that generates core dumps
  for 32bit processes (code that might be broken as well!).
'struct safefpu' is now identical to 'struct fxsave64'. One (or both)
  needs extending to support AVX - might need to be dynamically sized.
Removed all the __aligned(16) except for the one in struct pcb itself.
  Only the copy used for the fsave instruction need be aligned.
