Ok, a grep shows that possible culprits (i.e. giving success to grep GENERIC_HARDIRQS arch/*/Kconfig, and using 0x4000000 as PREEMPT_ACTIVE, as given by grep PREEMPT_ACTIVE include/asm-*/thread_info.h) are (at a first glance): frv, sh, sh64.
After a bit of checking, I also verified if they had overriden the value of HARDIRQ_BITS. Which they haven't (it seems it's defined exactly where CONFIG_HARDIRQS is not used, i.e. nobody is using the ability to override it currently). This was not a very deep investigation, however, so feel free to verify this better. -- Paolo Giarrusso, aka Blaisorblade Skype user "PaoloGiarrusso" Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ___________________________________ Yahoo!
