Just FYI if someone needs similar fix, backporting this: https://patchwork.kernel.org/patch/9170055/ fixed the issue for me, now I have successful kernel build. The failing code was always in put_user calls, e.g. kernel/exit.s was showing: @ 1581 "kernel-source/kernel/exit.c" 1 .ifnc r0,r0; .ifnc r0r0,fpr11; .ifnc r0r0,r11fp; .ifnc r0r0,ipr12; .ifnc r0r0,r12ip; .err; .endif; .endif; .endif; .endif; .endif .ifnc r5,r2; .ifnc r5r2,fpr11; .ifnc r5r2,r11fp; .ifnc r5r2,ipr12; .ifnc r5r2,r12ip; .err; .endif; .endif; .endif; .endif; .endif .ifnc r1,r1; .ifnc r1r1,fpr11; .ifnc r1r1,r11fp; .ifnc r1r1,ipr12; .ifnc r1r1,r12ip; .err; .endif; .endif; .endif; .endif; .endif bl __put_user_4 @ 0 "" 2 with the error triggered on the middle line. /tmp/ccHq8ugv.s: Assembler messages: /tmp/ccHq8ugv.s:1179: Error: .err encountered /tmp/ccHq8ugv.s:1331: Error: .err encountered /tmp/ccHq8ugv.s:4617: Error: .err encountered /tmp/ccHq8ugv.s:6222: Error: .err encountered /tmp/ccHq8ugv.s:8705: Error: .err encountered /tmp/ccHq8ugv.s:14486: Error: .err encountered /tmp/ccHq8ugv.s:14646: Error: .err encountered /tmp/ccHq8ugv.s:14806: Error: .err encountered /tmp/ccHq8ugv.s:14966: Error: .err encountered /tmp/ccHq8ugv.s:15126: Error: .err encountered /tmp/ccHq8ugv.s:15286: Error: .err encountered That leaves only few issues in our internal components and strange failure with perf which fails to include various header files: perf/1.0-r9/perf-1.0/tools/perf/util/include/asm/byteorder.h:2:10: fatal error: ../../../../include/uapi/linux/swab.h: No such file or directory perf/1.0-r9/perf-1.0/tools/perf/util/include/asm/byteorder.h:2:10: fatal error: ../../../../include/uapi/linux/swab.h: No such file or directory perf/1.0-r9/perf-1.0/tools/perf/util/include/asm/byteorder.h:2:10: fatal error: ../../../../include/uapi/linux/swab.h: No such file or directory perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:1:28: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:2:26: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:3:25: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:5:41: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/asm/byteorder.h:2:10: fatal error: ../../../../include/uapi/linux/swab.h: No such file or directory perf/1.0-r9/perf-1.0/tools/perf/util/include/asm/byteorder.h:2:10: fatal error: ../../../../include/uapi/linux/swab.h: No such file or directory perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:1:28: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:2:26: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:3:25: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:5:41: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:1:28: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:2:26: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:3:25: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:5:41: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/asm/byteorder.h:2:10: fatal error: ../../../../include/uapi/linux/swab.h: No such file or directory perf/1.0-r9/perf-1.0/tools/perf/util/include/asm/byteorder.h:2:10: fatal error: ../../../../include/uapi/linux/swab.h: No such file or directory perf/1.0-r9/perf-1.0/tools/perf/util/include/asm/byteorder.h:2:10: fatal error: ../../../../include/uapi/linux/swab.h: No such file or directory perf/1.0-r9/perf-1.0/tools/perf/util/include/asm/byteorder.h:2:10: fatal error: ../../../../include/uapi/linux/swab.h: No such file or directory perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:1:28: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:2:26: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:3:25: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/../../../include/linux/list.h:5:41: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/util/include/asm/byteorder.h:2:10: fatal error: ../../../../include/uapi/linux/swab.h: No such file or directory perf/1.0-r9/perf-1.0/tools/perf/arch/arm/include/../../../../include/asm-generic/bitops/fls.h:1:56: error: #include nested too deeply perf/1.0-r9/perf-1.0/tools/perf/arch/arm/include/../../../../include/asm-generic/bitops/fls.h:1:56: error: #include nested too deeply ...
