[Qemu-devel] [for-2.6 PATCH 2/3] target-i386: Use xsave structs for ext_save_area |

This doesn't introduce any change in the code, as the offsets and
struct sizes match what was present in the table. This can be
validated by the QEMU_BUILD_BUG_ON lines on target-i386/cpu.h,
which ensures the struct sizes and offsets match the existing
values in ext_save_area.
