Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! 2005-04-16 16:20:36 -06:00			`menu "Kernel hacking"`

[SPARC32]: Add irqflags.h to sparc32 and use it from generic code. Added asm-sparc/irqflags.h and moved irq related code from system.h to it. Renamed local_irq functions to raw_local_irq in irq.c. Modified system.h to include linux/irqflags.h which includes asm/irqflags.h. Added TRACE_IRQFLAGS_SUPPORT to Kconfig.debug. This is the first step in adding IRQ-flags state tracing as outlined in Documentation/irqflags-tracing.txt. These changes should be harmless because they just move things around and rename them. The next step is making the lowlevel entry code modifications which to be honest are beyond my capabilities at this point. Boot tested on an ss20 running an SMP kernel.

generic debug pagealloc CONFIG_DEBUG_PAGEALLOC is now supported by x86, powerpc, sparc64, and s390. This patch implements it for the rest of the architectures by filling the pages with poison byte patterns after free_pages() and verifying the poison patterns before alloc_pages(). This generic one cannot detect invalid page accesses immediately but invalid read access may cause invalid dereference by poisoned memory and invalid write access can be detected after a long delay.
