Hi, Sam & Ralf Perhaps we also need to fix the following stuff: ... LD vmlinux SYSMAP System.map SYSMAP .tmp_System.map mips64el-unknown-linux-gnu-objcopy -O elf32-tradlittlemips --remove-section=.reginfo vmlinux vmlinux.32 AS arch/mips/boot/compressed/head.o CC arch/mips/boot/compressed/decompress.o CC arch/mips/boot/compressed/dbg.o ... The related Makefile is arch/mips/Makefile: > 721 # > 722 # Some machines like the Indy need 32-bit ELF binaries for booting purposes. > 723 # Other need ECOFF, so we build a 32-bit ELF binary for them which we then > 724 # convert to ECOFF using elf2ecoff. > 725 # > 726 vmlinux.32: vmlinux > 727 $(OBJCOPY) -O $(32bit-bfd) $(OBJCOPYFLAGS) $< $@ > 728 > 729 # > 730 # The 64-bit ELF tools are pretty broken so at this time we generate 64-bit > 731 # ELF files from 32-bit files by conversion. > 732 # > 733 vmlinux.64: vmlinux > 734 $(OBJCOPY) -O $(64bit-bfd) $(OBJCOPYFLAGS) $< $@ Best Regards, Wu Zhangjin On Sun, 2010-05-30 at 16:19 +0200, Sam Ravnborg wrote: > This patchset does the following: > - introduce arch/mips/Kbuild > - use -Werror on all core-y files of the mips kernel > - introduce a distributed way to specify platform definitions > - refactor a few Makefiles > - clean up cleaning > > Ralf asked in private mail if I could try to implement > a working varient of a suggestion I made some time ago. > The idea was to move platform specific definitions to > dedicated platfrom files. > > This is implmented in the third patch. > > The idea is to move the platform definitions from arch/mips/Makefile > to arch/mips/<platform>/Platfrom > > The content of this file is used in arch/mips/Makefile > and arch/mips/Kbuild. > > On top of this is a few patches that refactor the > boot and boot/compressed Makefiles so they are more > kbuild conformant. > This beautify the output when we build a kernel. > > Wu Zhangjin have pointed out a few bugs in the first > variants of the patches that hit the mailing list - thanks! > > > Patches will follow. > > Note: I tried to test a little with bigsur_defconfig > but get_user() is buggy.
