Hi, I see the following build error in -next when building sh:rts7751r2dplus_defconfig.
sh4-linux-ld: arch/sh/kernel/vsyscall/vsyscall-dummy.o: compiled for a big endian system and target is little endian sh4-linux-ld: arch/sh/kernel/vsyscall/vsyscall-dummy.o: uses instructions which are incompatible with instructions used in previous modules sh4-linux-ld: failed to merge target specific data of file arch/sh/kernel/vsyscall/vsyscall-dummy.o make[2]: *** [arch/sh/kernel/vsyscall/vsyscall-syms.o] Error 1 Bisect points to 'sh: thin archives fix linking' as the culprit. Bisect log is attached. I tried with gcc 4.8.3 and 6.3.0, both built with buildroot for sh4eb. After reverting the offending patch, I get the following error. arch/sh/kernel/signal_32.o: In function `do_signal': signal_32.c:(.text+0x5c4): undefined reference to `__kernel_sigreturn' signal_32.c:(.text+0x724): undefined reference to `__kernel_rt_sigreturn' Makefile:989: recipe for target 'vmlinux' failed Guenter --- # bad: [89a39f3c7086301342175c461c4db43c68d34cc7] Add linux-next specific files for 20170627 # good: [c0bc126f97fb929b3ae02c1c62322645d70eb408] Linux 4.12-rc7 git bisect start 'HEAD' 'v4.12-rc7' # bad: [32e240e33387e1c3dcf302518d4420e7f19d51e2] Merge remote-tracking branch 'crypto/master' git bisect bad 32e240e33387e1c3dcf302518d4420e7f19d51e2 # bad: [5fa6b60a63a80c0d1adc4a7d2478fc7d22593493] Merge remote-tracking branch 'printk/for-next' git bisect bad 5fa6b60a63a80c0d1adc4a7d2478fc7d22593493 # bad: [99f4c8ff2a80c7c39dfd5558bda9f125313fc7ef] Merge remote-tracking branch 'arm-soc/for-next' git bisect bad 99f4c8ff2a80c7c39dfd5558bda9f125313fc7ef # good: [fff3affce6cd166063a56528e42eaf16c6a901b8] Merge branch 'next/dt' into for-next git bisect good fff3affce6cd166063a56528e42eaf16c6a901b8 # good: [88ad71aab1a7931ac3d35c3acaa431c3dc05afd9] [media] vimc: sen: Support several image formats git bisect good 88ad71aab1a7931ac3d35c3acaa431c3dc05afd9 # bad: [2bbc45806045b005f6a0f6db22a341f52622aca8] Merge remote-tracking branch 'asm-generic/master' git bisect bad 2bbc45806045b005f6a0f6db22a341f52622aca8 # bad: [fd47ada97a68d8be20dbdc115343f9d51bdf3714] Merge remote-tracking branch 'kbuild/for-next' git bisect bad fd47ada97a68d8be20dbdc115343f9d51bdf3714 # good: [1887a40b8699a8bde4a0b2883a1381c0a6e119e6] Merge remote-tracking branch 'net/master' git bisect good 1887a40b8699a8bde4a0b2883a1381c0a6e119e6 # bad: [39be5eac380dabc761c47358cdf8036bb5090f6b] Merge branches 'misc', 'kbuild' and 'thin-ar' into for-next git bisect bad 39be5eac380dabc761c47358cdf8036bb5090f6b # bad: [e7238f4fac14967bba823ef4b4b77ee928a4860a] kbuild: thin archives make default for all archs git bisect bad e7238f4fac14967bba823ef4b4b77ee928a4860a # good: [9fc5b7bc3c905ad207f21e8478659f4b935407c4] kbuild: handle libs-y archives separately from built-in.o archives git bisect good 9fc5b7bc3c905ad207f21e8478659f4b935407c4 # bad: [11690a748f62365890a9a9f9abf56ada9b7d5c40] ia64: thin archives fix linking git bisect bad 11690a748f62365890a9a9f9abf56ada9b7d5c40 # bad: [e2c99c9125c39eb43960da79f5691126b55d4b6c] sh: thin archives fix linking git bisect bad e2c99c9125c39eb43960da79f5691126b55d4b6c # first bad commit: [e2c99c9125c39eb43960da79f5691126b55d4b6c] sh: thin archives fix linking
