Commit f9afbd45b0d0 broke mips r4k.
My aboriginal linux project builds tiny linux systems to run under qemu, producing as close to the same system as possible across a bunch of different architectures. The above change broke the mips r4k build I've been running under qemu. Here's a toolchain and reproduction sequence: wget http://landley.net/aboriginal/bin/cross-compiler-mips.tar.bz2 tar xvjf cross-compiler-mips.tar.bz2 export PATH=$PWD/cross-compiler-mips/bin:$PATH make ARCH=mips allnoconfig KCONFIG_ALLCONFIG=miniconfig.mips make CROSS_COMPILE=mips- ARCH=mips (The file miniconfig.mips is attached.) It ends: CC init/version.o LD init/built-in.o arch/mips/built-in.o: In function `local_r4k_flush_cache_page': c-r4k.c:(.text+0xe278): undefined reference to `kvm_local_flush_tlb_all' c-r4k.c:(.text+0xe278): relocation truncated to fit: R_MIPS_26 against `kvm_local_flush_tlb_all' arch/mips/built-in.o: In function `local_flush_tlb_range': (.text+0xe938): undefined reference to `kvm_local_flush_tlb_all' arch/mips/built-in.o: In function `local_flush_tlb_range': (.text+0xe938): relocation truncated to fit: R_MIPS_26 against `kvm_local_flush_tlb_all' arch/mips/built-in.o: In function `local_flush_tlb_mm': (.text+0xed38): undefined reference to `kvm_local_flush_tlb_all' arch/mips/built-in.o: In function `local_flush_tlb_mm': (.text+0xed38): relocation truncated to fit: R_MIPS_26 against `kvm_local_flush_tlb_all' kernel/built-in.o: In function `__schedule': core.c:(.sched.text+0x16a0): undefined reference to `kvm_local_flush_tlb_all' core.c:(.sched.text+0x16a0): relocation truncated to fit: R_MIPS_26 against `kvm_local_flush_tlb_all' mm/built-in.o: In function `use_mm': (.text+0x182c8): undefined reference to `kvm_local_flush_tlb_all' mm/built-in.o: In function `use_mm': (.text+0x182c8): relocation truncated to fit: R_MIPS_26 against `kvm_local_flush_tlb_all' fs/built-in.o:(.text+0x7b50): more undefined references to `kvm_local_flush_tlb_all' follow fs/built-in.o: In function `flush_old_exec': (.text+0x7b50): relocation truncated to fit: R_MIPS_26 against `kvm_local_flush_tlb_all' Revert the above commit and it builds to the end.
