2008-12-04sparc: prepare kernel/ for unificationSam Ravnborg
o sparc32 files with identical names to sparc64 renamed to <name>_32.S o introduced a few Kconfig helpers to simplify Makefile logic o refactored Makefile to prepare for unification - use obj-$(CONFIG_SPARC32) for sparc32 specific files - use <name>_$(BITS) for files where sparc64 has a _64 variant - sparc64 directly include a few files where sparc32 builds them, refer to these files directly (no BITS) - sneaked in -Werror as used by sparc64 o modified sparc/Makefile to use the new names for head/init_task Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

2007-10-23[SPARC, XEN, NET/CXGB3] use irq_handler_t where appropriateJeff Garzik

2007-10-13[SPARC32]: Add irqflags.h to sparc32 and use it from generic code.Robert Reif
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.

2006-12-13[PATCH] getting rid of all casts of k[cmz]alloc() callsRobert P. J. Day
Run this: #!/bin/sh for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do echo "De-casting $f..." perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f done And then go through and reinstate those cases where code is casting pointers to non-pointers. And then drop a few hunks which conflicted with outstanding work.

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.

2005-04-16Linux-2.6.12-rc2v2.6.12-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!
