But let's keep some code quality standards here, and not # accept outrageously bad code. # # Link: https://lore.kernel.org/lkml/CAHk-=wgV9toS7GU3KmNpj8hCS9SeF+A0voHS8F275_mgLhL4Lw@mail.gmail.com/ # Cc: Andy Lutomirski <luto@kernel.org> # Cc: Thomas Gleixner <tglx@linutronix.de> # Cc: Peter Zijlstra (Intel) <peterz@infradead.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 bb5a93aaf25261321db0c499cde7da6ee9d8b164 # < make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- allyesconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- olddefconfig # make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- /kisskb/src/drivers/scsi/dc395x.c: In function '__dc395x_eh_bus_reset': /kisskb/src/drivers/scsi/dc395x.c:155:36: warning: value computed is not used [-Wunused-value] #define DC395x_read8(acb,address) (u8)(inb(acb->io_port_base + (address))) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/scsi/dc395x.c:1197:2: note: in expansion of macro 'DC395x_read8' DC395x_read8(acb, TRM_S1040_SCSI_INTSTATUS); ^~~~~~~~~~~~ /kisskb/src/drivers/scsi/dc395x.c: In function 'set_basic_config': /kisskb/src/drivers/scsi/dc395x.c:155:36: warning: value computed is not used [-Wunused-value] #define DC395x_read8(acb,address) (u8)(inb(acb->io_port_base + (address))) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/scsi/dc395x.c:3489:2: note: in expansion of macro 'DC395x_read8' DC395x_read8(acb, TRM_S1040_SCSI_INTSTATUS); ^~~~~~~~~~~~ /kisskb/src/drivers/scsi/dc395x.c: In function 'adapter_uninit_chip': /kisskb/src/drivers/scsi/dc395x.c:155:36: warning: value computed is not used [-Wunused-value] #define DC395x_read8(acb,address) (u8)(inb(acb->io_port_base + (address))) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/scsi/dc395x.c:4435:2: note: in expansion of macro 'DC395x_read8' DC395x_read8(acb, TRM_S1040_SCSI_INTSTATUS); ^~~~~~~~~~~~ /kisskb/src/drivers/input/joystick/analog.c:160:2: warning: #warning Precise timer not defined for this architecture.
