From 3f550096dede4430f83b16457da83bf429155ac2 Mon Sep 17 00:00:00 2001 From: Mathieu Desnoyers Date: Sat, 2 Feb 2008 15:10:35 -0500 Subject: Add HAVE_KPROBES Linus: On the per-architecture side, I do think it would be better to *not* have internal architecture knowledge in a generic file, and as such a line like depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32 really shouldn't exist in a file like kernel/Kconfig.instrumentation. It would be much better to do depends on ARCH_SUPPORTS_KPROBES in that generic file, and then architectures that do support it would just have a bool ARCH_SUPPORTS_KPROBES default y in *their* architecture files. That would seem to be much more logical, and is readable both for arch maintainers *and* for people who have no clue - and don't care - about which architecture is supposed to support which interface... Changelog: Actually, I know I gave this as the magic incantation, but now that I see it, I realize that I should have told you to just use config KPROBES_SUPPORT def_bool y instead, which is a bit denser. We seem to use both kinds of syntax for these things, but this is really what "def_bool" is there for... - Use HAVE_KPROBES - Use a select - Yet another update : Moving to HAVE_* now. - Update ARM for kprobes support.
