x86, relocs: Refactor the relocs tool to merge 32- and 64-bit ELF Refactor the relocs tool so that the same tool can handle 32- and 64-bit ELF. Signed-off-by: H.

x86, relocs: Build separate 32/64-bit tools Since the ELF structures and access macros change size based on 32 vs 64 bits, build a separate 32-bit relocs tool (for handling realmode and 32-bit relocations), and a 64-bit relocs tool (for handling 64-bit kernel relocations).

x86, realmode: 16-bit real-mode code support for relocs tool A new option is added to the relocs tool called '--realmode'. This option causes the generation of 16-bit segment relocations and 32-bit linear relocations for the real-mode code. When the real-mode code is moved to the low-memory during kernel initialization, these relocation entries can be used to relocate the code properly. In the assembly code 16-bit segment relocations must be relative to the 'real_mode_seg' absolute symbol. Linear relocations must be relative to a symbol prefixed with 'pa_'. 16-bit segment relocation is used to load cs:ip in 16-bit code. Linear relocations are used in the 32-bit code for relocatable data references. They are declared in the linker script of the real-mode code. The relocs tool is moved to arch/x86/tools/relocs.c, and added new target archscripts that can be used to build scripts needed building an architecture. be compiled before building the arch/x86 tree. [ hpa: accelerating this because it detects invalid absolute relocations, a serious bug in binutils 2.22.52.0.x which currently produces bad kernels. ] Signed-off-by: H.
