Subject: [ARM] Arrange asm-arm/elf.h so it can be included by assembly
X-Git-Tag: v2.6.20-rc1~15^2~2^2~7^2^3~35
X-Git-Url: http://git.rot13.org/?a=commitdiff_plain;h=4a5222ca435c2af7466e5d262389609978a8e576;p=powerpc.git

[ARM] Arrange asm-arm/elf.h so it can be included by assembly

Prepare elf.h so that assembly code can include this file.
