2018-10-16lib: Fix ia64 bootloader linkageAlexander Shishkin
kbuild robot reports that since commit ce76d938dd98 ("lib: Add memcat_p(): paste 2 pointer arrays together") the ia64/hp/sim/boot fails to link: > LD arch/ia64/hp/sim/boot/bootloader > lib/string.o: In function `__memcat_p': > string.c:(.text+0x1f22): undefined reference to `__kmalloc' > string.c:(.text+0x1ff2): undefined reference to `__kmalloc' > make[1]: *** [arch/ia64/hp/sim/boot/Makefile:37: arch/ia64/hp/sim/boot/bootloader] Error 1 The reason is, the above commit, via __memcat_p(), adds a call to __kmalloc to string.o, which happens to be used in the bootloader, but there's no kmalloc or slab or anything. Since the linker would only pull in objects that contain referenced symbols, moving __memcat_p() to a different compilation unit solves the problem.
