And on 64-bit architectures it causes warnings. # # Admittedly, 64-bit architectures with ISA are basically dead - I think # the only example of this is alpha, and nobody would ever use the dmascc # driver there. But hey, the fix is easy enough, the end result is # cleaner, and it's yet another configuration that now builds without # warnings. # # If somebody actually uses this driver on an alpha and this fixes it for # you, please email me. Because that is just incredibly bizarre. # # Signed-off-by: Linus Torvalds # < /opt/cross/kisskb/korg/gcc-10.1.0-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-10.1.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 bc1abb9e55cedaeac4602426f8fc83fb3a5b1c35 # < make -s -j 48 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc10 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-10.1.0-nolibc/sh4-linux/bin/sh4-linux- se7619_defconfig # < make -s -j 48 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc10 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-10.1.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 48 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc10 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-10.1.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 48 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc10 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-10.1.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h :1515:2: warning: #warning syscall clone3 not implemented [-Wcpp] In file included from /kisskb/src/arch/sh/include/asm/hw_irq.h:6, from /kisskb/src/include/linux/irq.h:593, from /kisskb/src/include/asm-generic/hardirq.h:17, from /kisskb/src/arch/sh/include/asm/hardirq.h:9, from /kisskb/src/include/linux/hardirq.h:11, from /kisskb/src/include/linux/interrupt.h:11, from /kisskb/src/include/linux/serial_core.h:13, from /kisskb/src/include/linux/serial_sci.h:6, from /kisskb/src/arch/sh/kernel/cpu/sh2/setup-sh7619.c:11: /kisskb/src/include/linux/sh_intc.h:100:63: warning: division 'sizeof (void *) / sizeof (void)' does not compute the number of array elements [-Wsizeof-pointer-div] 100 | #define _INTC_ARRAY(a) a, __same_type(a, NULL) ? 0 : sizeof(a)/sizeof(*a) | ^ /kisskb/src/include/linux/sh_intc.h:105:24: note: in expansion of macro '_INTC_ARRAY' 105 | _INTC_ARRAY(vectors), _INTC_ARRAY(groups), \ | ^~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:124:8: note: in expansion of macro 'INTC_HW_DESC' 124 | .hw = INTC_HW_DESC(vectors, groups, mask_regs, \ | ^~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/sh2/setup-sh7619.c:58:8: note: in expansion of macro 'DECLARE_INTC_DESC' 58 | static DECLARE_INTC_DESC(intc_desc, "sh7619", vectors, NULL, | ^~~~~~~~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:100:63: warning: division 'sizeof (void *) / sizeof (void)' does not compute the number of array elements [-Wsizeof-pointer-div] 100 | #define _INTC_ARRAY(a) a, __same_type(a, NULL) ? 0 : sizeof(a)/sizeof(*a) | ^ /kisskb/src/include/linux/sh_intc.h:106:2: note: in expansion of macro '_INTC_ARRAY' 106 | _INTC_ARRAY(mask_regs), _INTC_ARRAY(prio_regs), \ | ^~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:124:8: note: in expansion of macro 'INTC_HW_DESC' 124 | .hw = INTC_HW_DESC(vectors, groups, mask_regs, \ | ^~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/sh2/setup-sh7619.c:58:8: note: in expansion of macro 'DECLARE_INTC_DESC' 58 | static DECLARE_INTC_DESC(intc_desc, "sh7619", vectors, NULL, | ^~~~~~~~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:100:63: warning: division 'sizeof (void *) / sizeof (void)' does not compute the number of array elements [-Wsizeof-pointer-div] 100 | #define _INTC_ARRAY(a) a, __same_type(a, NULL) ? 0 : sizeof(a)/sizeof(*a) | ^ /kisskb/src/include/linux/sh_intc.h:107:2: note: in expansion of macro '_INTC_ARRAY' 107 | _INTC_ARRAY(sense_regs), _INTC_ARRAY(ack_regs), \ | ^~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:124:8: note: in expansion of macro 'INTC_HW_DESC' 124 | .hw = INTC_HW_DESC(vectors, groups, mask_regs, \ | ^~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/sh2/setup-sh7619.c:58:8: note: in expansion of macro 'DECLARE_INTC_DESC' 58 | static DECLARE_INTC_DESC(intc_desc, "sh7619", vectors, NULL, | ^~~~~~~~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:100:63: warning: division 'sizeof (void *) / sizeof (void)' does not compute the number of array elements [-Wsizeof-pointer-div] 100 | #define _INTC_ARRAY(a) a, __same_type(a, NULL) ? 0 : sizeof(a)/sizeof(*a) | ^ /kisskb/src/include/linux/sh_intc.h:107:27: note: in expansion of macro '_INTC_ARRAY' 107 | _INTC_ARRAY(sense_regs), _INTC_ARRAY(ack_regs), \ | ^~~~~~~~~~~ /kisskb/src/include/linux/sh_intc.h:124:8: note: in expansion of macro 'INTC_HW_DESC' 124 | .hw = INTC_HW_DESC(vectors, groups, mask_regs, \ | ^~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/sh2/setup-sh7619.c:58:8: note: in expansion of macro 'DECLARE_INTC_DESC' 58 | static DECLARE_INTC_DESC(intc_desc, "sh7619", vectors, NULL, | ^~~~~~~~~~~~~~~~~ /kisskb/src/drivers/tty/serial/sh-sci.c: In function 'sci_remap_port': /kisskb/src/drivers/tty/serial/sh-sci.c:2662:19: warning: unused variable 'sport' [-Wunused-variable] 2662 | struct sci_port *sport = to_sci_port(port); | ^~~~~ Completed OK # rm -rf /kisskb/build/linus_se7619_defconfig_sh4-gcc10 # Build took: 0:00:27.882513
