* sparc: Provide NO_IRQ definition.David S. Miller2011-03-181-0/+2

* sparc64: rename virt_irq => irq - IISam Ravnborg2011-03-171-9/+9
| | | | | | | | | | | The generic irq support uses the term 'irq' for the allocated irq number. Fix it so sparc64 use the same term for an irq as the generic irq support does. For a naive reader this is less confusing. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* debug lockups: Improve lockup detection, fix generic arch fallbackIngo Molnar2009-08-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | As Andrew noted, my previous patch ("debug lockups: Improve lockup detection") broke/removed SysRq-L support from architecture that do not provide a __trigger_all_cpu_backtrace implementation. Restore a fallback path and clean up the SysRq-L machinery a bit: - Rename the arch method to arch_trigger_all_cpu_backtrace() - Simplify the define - Document the method a bit - in the hope of more architectures adding support for it. [ The patch touches Sparc code for the rename. ] Cc: Paul E.

* sparc, sparc64: use arch/sparc/includeSam Ravnborg2008-07-271-0/+93
The majority of this patch was created by the following script: *** ASM=arch/sparc/include/asm mkdir -p $ASM git mv include/asm-sparc64/ftrace.h $ASM git rm include/asm-sparc64/* git mv include/asm-sparc/* $ASM sed -ie 's/asm-sparc64/asm/g' $ASM/* sed -ie 's/asm-sparc/asm/g' $ASM/* *** The rest was an update of the top-level Makefile to use sparc for header files when sparc64 is being build. And a small fixlet to pick up the correct unistd.h from sparc64 code. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
