Yes. My version is v0.5.2-853-g06a4545 I only see './include/linux/slab.h:332:43: warning: dubious: x & !y' in linux-next. The warning in slab.h is already on the way in mm subsystem. masahiro@pug:~/ref/linux-next$ git log --oneline -1 9d52999 Add linux-next specific files for 20181127 masahiro@pug:~/ref/linux-next$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- C=2 defconfig drivers/dma/uniphier-mdmac.o *** Default configuration is based on 'defconfig' # # configuration written to .config # scripts/kconfig/conf --syncconfig Kconfig CHECK scripts/mod/empty.c CC scripts/mod/empty.o MKELF scripts/mod/elfconfig.h HOSTCC scripts/mod/modpost.o CC scripts/mod/devicetable-offsets.s HOSTCC scripts/mod/file2alias.o HOSTCC scripts/mod/sumversion.o HOSTLD scripts/mod/modpost CC kernel/bounds.s UPD include/generated/bounds.h UPD include/generated/timeconst.h CC arch/arm64/kernel/asm-offsets.s UPD include/generated/asm-offsets.h CALL scripts/checksyscalls.sh <stdin>:1338:2: warning: #warning syscall open_tree not implemented [-Wcpp] <stdin>:1341:2: warning: #warning syscall move_mount not implemented [-Wcpp] <stdin>:1344:2: warning: #warning syscall fsopen not implemented [-Wcpp] <stdin>:1347:2: warning: #warning syscall fsconfig not implemented [-Wcpp] <stdin>:1350:2: warning: #warning syscall fsmount not implemented [-Wcpp] <stdin>:1353:2: warning: #warning syscall fspick not implemented [-Wcpp] <stdin>:1356:2: warning: #warning syscall fsinfo not implemented [-Wcpp] CALL scripts/atomic/check-atomics.sh LDS arch/arm64/kernel/vdso/vdso.lds VDSOA arch/arm64/kernel/vdso/gettimeofday.o VDSOA arch/arm64/kernel/vdso/sigreturn.o VDSOL arch/arm64/kernel/vdso/vdso.so.dbg VDSOSYM include/generated/vdso-offsets.h CHECK drivers/dma/uniphier-mdmac.c ./include/linux/slab.h:332:43: warning: dubious: x & !y CC drivers/dma/uniphier-mdmac.o > > ./include/linux/overflow.h:285:13: error: undefined identifier > > '__builtin_mul_overflow' > > ./include/linux/overflow.h:285:13: error: incorrect type in conditional > > ./include/linux/overflow.h:285:13: got void > > ./include/linux/overflow.h:287:13: error: undefined identifier > > '__builtin_add_overflow' > > ./include/linux/overflow.h:287:13: error: incorrect type in conditional > > ./include/linux/overflow.h:287:13: got void > > ./include/linux/overflow.h:285:13: warning: call with no type! > > ./include/linux/overflow.h:287:13: warning: call with no type! > > and I was also talking about: > > arch/arm64/include/asm/sysreg.h:471:42: warning: constant 0xffffffffffffffff is so big it is unsigned long > arch/arm64/include/asm/sysreg.h:512:42: warning: constant 0xffffffffffffffff is so big it is unsigned long > include/linux/slab.h:332:43: warning: dubious: x & !y > > -- > ~Vinod -- Best Regards Masahiro Yamada
