This patch cleans up the ELF headers and their users. It does several
related things:
1. split linux/elf.h into pieces
This splits linux/elf.h into several pieces:
linux/elf.h - still the common elf header,
functionally unchanged
linux/elf-const.h - ELF constants, includable by asm code
linux/elf-decl.h - ELF type declarations, without definitions
linux/elf-defn.h - ELF type definitions
This makes it easier to use the ELF headers in various contexts such
as assembler and boot code, without pulling in a lot of other unneeded
headers.
2. add asm-*/elf-defines.h, and asm-generic/elf(32|64)-defines.h
Architectures define some arch-specific ELF definitions.
The most basic of these is whether they want to use a 32 or 64 bit ELF
class, and their associated types. These common definitions have been
put into asm-generic/elf(32|64)-defines.h, so that a simple
architecture can simply include the appropriate generic header in its
asm/elf-defines.h.
The effect of including asm/elf-defines.h in any code is that you get
the architecture's preferred ELF_CLASS defined, and the generic types
(Elf_Ehdr, Elf_Phdr, etc) are defined to the appropriate class types
(Elf32_Ehdr, etc).
For most architectures this transition was straightforward, but some
need special handling:
mips, powerpc, s390 allow both 32 and 64 bit operation. powerpc's
logic for this was particularly complex, so I just copied the code
outright into asm-powerpc/elf-defines.h and hope that it's right.
powerpc also appears to have its own duplicate copy of elf.h in
arch/powerpc/boot/elf.h; presumably because the standard elf.h
brings in too much. Update it to just linux/elf-defn.h, which
should be fine.
x86-64 does some mucking about with ELF_CLASS in order to make
fs/binfmt_elf also handle 32-bit binaries. This is why
asm-generic/elf(32|64)_defines.h only conditionally define
ELF_CLASS.
3. Narrow elf.h includes.
Some headers, such as linux/modules.h, are included by a large
proportion of the kernel code, and end up including linux/elf.h which
in turn includes a lot of other headers. In practice, linux/modules.h
only wants a couple of ELF type declarations, and so can make do with
asm/elf-defines.h, which includes very little.
A side effect of this is that some files were depending on
linux/elf.h's implicit includes, and so needed to have some extra
headers for the definitions they require.
Unfortunately I don't have the means to cross-build all the
architectures, but I did an cross builds of i386, x86-64, sparc64 and
powerpc and fixed up what I found.
