*	elf coredump: replace ELF_CORE_EXTRA_* macros by functions	Daisuke HATAYAMA	2010-03-06	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	elf_core_dump() and elf_fdpic_core_dump() use #ifdef and the corresponding macro for hiding _multiline_ logics in functions. This patch removes #ifdef and replaces ELF_CORE_EXTRA_* by corresponding functions. For architectures not implemeonting ELF_CORE_EXTRA_*, we use weak functions in order to reduce a range of modification. This cleanup is for my next patches, but I think this cleanup itself is worth doing regardless of my firnal purpose.

*	x86: compat_binfmt_elf	Roland McGrath	2008-01-30	1	-0/+131
	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.
