x86: compat_binfmt_elf
This adds fs/compat_binfmt_elf.c, a wrapper around fs/binfmt_elf.c for 32-bit ELF support on 64-bit kernels. It can replace all the hand-rolled versions of this that each 32/64 arch has, which are all about the same. To use this, an arch's asm/elf.h has to define at least a few compat_* macros that parallel the various macros that fs/binfmt_elf.c uses for native support. There is no attempt to deal with compat macros for the core dump format support. To use this file, the arch has to define compat_gregset_t for linux/elfcore-compat.h and #define CORE_DUMP_USE_REGSET. The 32-bit compatible formats should come automatically from task_user_regset_view called on a 32-bit task.
