These macros skip the type checking, # and as such need to be very sparingly used only for obvious cases that # have active issues like this. # # Reported-by: Lorenzo Stoakes <lorenzo.stoakes@oracle.com> # Link: https://lore.kernel.org/all/36aa2cad-1db1-4abf-8dd2-fb20484aabc3@lucifer.local/ # Cc: David Laight <David.Laight@aculab.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 3a7e02c040b130b5545e4b115aada7bacd80a2b6 # make -s -j 160 ARCH=sh O=/kisskb/build/linus_defconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- defconfig # < make -s -j 160 ARCH=sh O=/kisskb/build/linus_defconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 160 ARCH=sh O=/kisskb/build/linus_defconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 160 ARCH=sh O=/kisskb/build/linus_defconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/kernel/locking/spinlock.c:68:17: warning: no previous prototype for '__raw_spin_lock' [-Wmissing-prototypes] 68 \| void __lockfunc __raw_##op##_lock(locktype##_t lock) \ \| ^~~~~~ /kisskb/src/kernel/locking/spinlock.c:126:1: note: in expansion of macro 'BUILD_LOCK_OPS' 126 \| BUILD_LOCK_OPS(spin, raw_spinlock);
