[PATCH] x86-64: Modpost whitelist reference to more symbols (pattern 3) o MODPOST generates warning on i386 if kernel is compiled with CONFIG_RELOCATABLE=y. WARNING: vmlinux - Section mismatch: reference to .init.text:__init_begin from .text between 'free_initmem' (at offset 0xc0114fd3) and 'do_test_wp_bit' WARNING: vmlinux - Section mismatch: reference to .init.text:_sinittext from .text between 'core_kernel_text' (at offset 0xc012aeae) and 'kernel_text_address' WARNING: vmlinux - Section mismatch: reference to .init.text:_einittext from .text between 'core_kernel_text' (at offset 0xc012aeb7) and 'kernel_text_address' WARNING: vmlinux - Section mismatch: reference to .init.text:_sinittext from .text between 'get_symbol_pos' (at offset 0xc0135776) and 'reset_iter' WARNING: vmlinux - Section mismatch: reference to .init.text:_einittext from .text between 'get_symbol_pos' (at offset 0xc013577d) and 'reset_iter' o These symbols (__init_begin, _sinittext, _einittext) belong to init section and generally represent a section boundary. These are special symbols in the sense that their size is zero and no memory is allocated for them in init section. Their addr and value are same. So even if we free the init section, it is ok to reference them. o Whitelist access to such select symbols in MODPOST.

kbuild: fix sh64 section mismatch problems There's a special .cranges section that is almost always generated, with data being moved to the appropriate section by the linker at a later stage. To give a bit of background, sh64 has both a native SHmedia instruction set (32-bit instructions) and SHcompact (which is compatability with normal SH -- 16-bit, a massively reduced register set, etc.). code ranges are emitted when we're using the 32-bit ABI, but not the 64-bit one. It is a special staging section used solely by binutils where code with different flags get placed (more specifically differing flags for input and output sections), before being lazily merged by the linker. The closest I've been able to find to documentation is: http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/ld/emultempl/sh64elf.em?rev=1.10&content-type=text/x-cvsweb-markup&cvsroot=src It's an array of 8-byte Elf32_CRange structure given in http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/bfd/elf32-sh64.h?rev=1.4&content-type=text/x-cvsweb-markup&cvsroot=src that describes for which ISA a range is used.
