2009-08-18sparc32: Kill trap table freeing code.David S. Miller
Normally, srmmu uses different trap table register values to allow determination of the cpu we're on. All of the trap tables have identical content, they just sit at different offsets from the first trap table, and the offset shifted down and masked out determines the cpu we are on. The code tries to free them up when they aren't actually used (don't have all 4 cpus, we're on sun4d, etc.) but that causes problems. For one thing it triggers false positives in the DMA debugging code. And fixing that up while preserving this relative offset thing isn't trivial. So just kill the freeing code, it costs us at most 3 pages, big deal... Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-16cpumask: prepare for iterators to only go to nr_cpu_ids/nr_cpumask_bits.: sparcRusty Russell
Impact: cleanup, futureproof In fact, all cpumask ops will only be valid (in general) for bit numbers < nr_cpu_ids. So use that instead of NR_CPUS in various places. This is always safe: no cpu number can be >= nr_cpu_ids, and nr_cpu_ids is initialized to NR_CPUS at boot.

2008-11-30sparc32 cpuinit flase positivesAl Viro
All noise since we don't have CPU hotplug there. However, they did expose something very odd-looking in there - poke_viking() does a bunch of identical btfixup each time it's called (i.e. for each CPU). That one is left alone for now; just the trivial misannotation fixes. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-09-08kernel/cpu.c: create a CPU_STARTING cpu_chain notifierManfred Spraul
Right now, there is no notifier that is called on a new cpu, before the new cpu begins processing interrupts/softirqs. Various kernel function would need that notification, e.g. kvm works around by calling smp_call_function_single(), rcu polls cpu_online_map. The patch adds a CPU_STARTING notification. It also adds a helper function that sends the message to all cpu_chain handlers. Tested on x86-64. All other archs are untested. Especially on sparc, I'm not sure if I got it right.

2008-02-06calibrate_delay() must be __cpuinitAdrian Bunk
calibrate_delay() must be __cpuinit, not __{dev,}init. I've verified that this is correct for all users. While doing the latter, I also did the following cleanups: - remove pointless additional prototypes in C files - ensure all users #include <linux/delay.h> This fixes the following section mismatches with CONFIG_HOTPLUG=n, CONFIG_HOTPLUG_CPU=y: WARNING: vmlinux.o(.text+0x1128d): Section mismatch: reference to .init.text.1:calibrate_delay (between 'check_cx686_slop' and 'set_cx86_reorder') WARNING: vmlinux.o(.text+0x25102): Section mismatch: reference to .init.text.1:calibrate_delay (between 'smp_callin' and 'cpu_coregroup_map') Signed-off-by: Adrian Bunk <bunk@kernel.org> Cc: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Cc: Richard Henderson <rth@twiddle.net> Cc: "Luck, Tony" <tony.luck@intel.com> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: "David S.

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.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
