On "normal" (defconfig) builds the warning does not show up because CONFIG_FRAME_POINTER is set. I've found the unused bp because CONFIG_FRAME_POINTER was not set in my configuration.
CC arch/um/kernel/sysrq.o arch/um/kernel/sysrq.c: In function ‘show_stack’: arch/um/kernel/sysrq.c:32:29: warning: unused variable ‘bp’ [-Wunused-variable]
It's reproducible on linus-tree (0429fbc0b) by make mrproper make tinyconfig ARCH=um SUBARCH=i386 make ARCH=um SUBARCH=i386
