4.1-stable review patch. If anyone has any objections, please let me know.
------------------ From: Lukas Wunner <[email protected]> commit 75e84ab906ef8935cff3df3d8929f1bafea81599 upstream. Invoking Makefile.perf with prefix= breaks the build since Makefile.perf hands that variable down to Makefile.build where it overrides prefix := $(subst ./,,$(OUTPUT)$(dir)/) leading to errors like this: No rule to make target '/usrabspath.o', needed by '/usrlibperf-in.o' Signed-off-by: Lukas Wunner <[email protected]> Acked-by: Jiri Olsa <[email protected]> Cc: David Ahern <[email protected]> Fixes: c819e2cf2eb6f65d3208d195d7a0edef6108d5 Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> --- tools/build/Makefile.build | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) --- a/tools/build/Makefile.build +++ b/tools/build/Makefile.build @@ -94,12 +94,12 @@ obj-y := $(patsubst %/, %/$(obj)- subdir-obj-y := $(filter %/$(obj)-in.o, $(obj-y)) # '$(OUTPUT)/dir' prefix to all objects -prefix := $(subst ./,,$(OUTPUT)$(dir)/) -obj-y := $(addprefix $(prefix),$(obj-y)) -subdir-obj-y := $(addprefix $(prefix),$(subdir-obj-y)) +objprefix := $(subst ./,,$(OUTPUT)$(dir)/) +obj-y := $(addprefix $(objprefix),$(obj-y)) +subdir-obj-y := $(addprefix $(objprefix),$(subdir-obj-y)) # Final '$(obj)-in.o' object -in-target := $(prefix)$(obj)-in.o +in-target := $(objprefix)$(obj)-in.o PHONY += $(subdir-y) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
