2007-07-21[SPARC32]: clean include/asm-sparc/irq.hAl Viro
Move stuff used only by arch/sparc/kernel/* into arch/sparc/kernel/irq.h and into individual files in there (e.g. macros internal to sun4m_irq.c, etc.) Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-05-08header cleaning: don't include smp_lock.h when not usedRandy Dunlap
Remove includes of <linux/smp_lock.h> where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs).

2006-03-23[SPARC]: Try to start getting SMP back into shape.Bob Breuer
Todo items: - IRQ_INPROGRESS flag - use sparc64 irq buckets, or generic irq_desc? - sun4d - re-indent large chunks of sun4m_smp.c - some places assume sequential cpu numbering (i.e. 0,1 instead of 0,2) Last I checked (with 2.6.14), random programs segfault with dual HyperSPARC. And with SuperSPARC II's, it seems stable but will eventually die from a write lock error (wrong lock owner or something). I haven't tried the HyperSPARC + highmem combination recently, so that may still be a problem. Signed-off-by: David S. Miller <davem@davemloft.net>
2006-03-23[PATCH] more for_each_cpu() conversionsAndrew Morton
When we stop allocating percpu memory for not-possible CPUs we must not touch the percpu data for not-possible CPUs at all. The correct way of doing this is to test cpu_possible() or to use for_each_cpu(). This patch is a kernel-wide sweep of all instances of NR_CPUS. I found very few instances of this bug, if any. But the patch converts lots of open-coded test to use the preferred helper macros.

2006-03-22[PATCH] remove set_page_count() outside mm/Nick Piggin
set_page_count usage outside mm/ is limited to setting the refcount to 1. Remove set_page_count from outside mm/, and replace those users with init_page_count() and set_page_refcounted(). This allows more debug checking, and tighter control on how code is allowed to play around with page->_count.

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!
