ftrace: fix merge buglet
-tip testing found a bootup hang here: initcall anon_inode_init+0x0/0x130 returned 0 after 0 msecs calling acpi_event_init+0x0/0x57 the bootup should have continued with: initcall acpi_event_init+0x0/0x57 returned 0 after 45 msecs but it hung hard there instead. bisection led to this commit: | commit 5806b81ac1c0c52665b91723fd4146a4f86e386b | Merge: d14c8a6... 6712e29... | Author: Ingo Molnar <mingo@elte.hu> | Date: Mon Jul 14 16:11:52 2008 +0200 | Merge branch 'auto-ftrace-next' into tracing/for-linus turns out that i made this mistake in the merge: ifdef CONFIG_FTRACE # Do not profile debug utilities CFLAGS_REMOVE_tsc_64.o = -pg CFLAGS_REMOVE_tsc_32.o = -pg those two files got unified meanwhile - so the dont-profile annotation got lost. The proper rule is: CFLAGS_REMOVE_tsc.o = -pg i guess this could have been caught sooner if the CFLAGS_REMOVE* kbuild rule aborted the build if it met a target that does not exist anymore?
