Hello everyone, Since the "reporting bugs" FAQ told me to post here in case I can't identify the right person to ask, and have not found any mention of this problem on the list and anywhere else yet, I do. Problem description: Compiling 2.6.18-git19 (gcc-3.3 and 4.1) fails for processor family i386 (when CONFIG_RWSEM_GENERIC_SPINLOCK=y) is set, with arch/i386/lib/lib.a(semaphore.o): In function `call_rwsem_down_read_failed': arch/i386/lib/semaphore.S:(.sched.text+0x5f): undefined reference to `rwsem_down_read_failed' arch/i386/lib/lib.a(semaphore.o): In function `call_rwsem_down_write_failed': arch/i386/lib/semaphore.S:(.sched.text+0x6a): undefined reference to `rwsem_down_write_failed' arch/i386/lib/lib.a(semaphore.o): In function `call_rwsem_wake': arch/i386/lib/semaphore.S:(.sched.text+0x76): undefined reference to `rwsem_wake' arch/i386/lib/lib.a(semaphore.o): In function `call_rwsem_downgrade_wake': arch/i386/lib/semaphore.S:(.sched.text+0x7f): undefined reference to `rwsem_downgrade_wake' This option is present in .config when setting processor family to plain "i386" in make menuconfig. Using CONFIG_RWSEM_XCHGADD_ALGORITHM=y INSTEAD of CONFIG_RWSEM_GENERIC_SPINLOCK=y (i486 and up) kind of "fixes" the compile error, but I'm not sure if the resulting code would still run on a real i386. This problem also exists for ealier gits, but I can't tell exactly when it started.
