2008-08-18[IA64] Shrink shadow_flush_counts to a short array to save 8k of per_cpu area.Robin Holt1-4/+4
Making allmodconfig will break the current build. This patch shrinks the per_cpu__shadow_flush_counts from 16k to 8k which frees enough space to allow allmodconfig to successfully complete.

2008-06-26on_each_cpu(): kill unused 'retry' parameterJens Axboe1-2/+2
It's not even passed on to smp_call_function() anymore, since that was removed. So kill it. Acked-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Reviewed-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-06-26ia64: convert to generic helpers for IPI function callsJens Axboe1-237/+13
This converts ia64 to use the new helpers for smp_call_function() and friends, and adds support for smp_call_function_single(). Cc: Tony Luck <tony.luck@intel.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-05-01[IA64] smp.c coding style fixHidetoshi Seto1-33/+35
Fix indenting of switch statement to follow CodingStyle, and pull out handling of call_data into an inlined function. I confirmed that applying this fix doesn't affect assembled code. Signed-off-by: Hidetoshi Seto <seto.hidetoshi@jp.fujitsu.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2008-04-03[IA64] Implement smp_call_function_mask for ia64Xiantao Zhang1-0/+82
This interface provides more flexible functionality for smp infrastructure ... e.g. KVM frequently needs to operate on a subset of cpus. Signed-off-by: Xiantao Zhang <xiantao.zhang@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2007-07-30[IA64] Allow smp_call_function_single() to current cpuAvi Kivity1-3/+5
This removes the requirement for callers to get_cpu() to check in simple cases. i386 and x86_64 already received a similar treatment. Signed-off-by: Avi Kivity <avi@qumranet.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

2007-07-19use the new percpu interface for shared dataFenghua Yu1-1/+1
Currently most of the per cpu data, which is accessed by different cpus, has a ____cacheline_aligned_in_smp attribute. Move all this data to the new per cpu shared data section: .data.percpu.shared_aligned. This will seperate the percpu data which is referenced frequently by other cpus from the local only percpu data.

2006-12-12[IA64] CONFIG_KEXEC/CONFIG_CRASH_DUMP permutationsHorms1-2/+2
Actually, on reflection I think that there is a good case for keeping the options separate. I am thinking particularly of people who want a very small crashdump kernel and thus don't want to compile in kexec. The patch below should fix things up so that all valid combinations of KEXEC, CRASH_DUMP and VMCORE compile cleanly - VMCORE depends on CRASH_DUMP which is why I said valid combinations. In a nutshell it just untangles unrelated code and switches around a few defines. Please note that it creats a new file, arch/ia64/kernel/crash_dump.c This is in keeping with the i386 implementation.

2005-10-25[IA64] wider use of for_each_cpu_mask() in arch/ia64hawkes@sgi.com1-5/+5
In arch/ia64 change the explicit use of for-loops and NR_CPUS into the general for_each_cpu() or for_each_online_cpu() constructs, as appropriate. This widens the scope of potential future optimizations of the general constructs, as well as takes advantage of the existing optimizations of first_cpu() and next_cpu().

2005-06-28[IA64] Fix another IA64 preemption problemPeter Chubb1-0/+3
There's another problem shown up by Ingo's recent patch to make smp_processor_id() complain if it's called with preemption enabled. local_finish_flush_tlb_mm() calls activate_context() in a situation where it could be rescheduled to another processor. This patch disables preemption around the call. Signed-off-by: Peter Chubb <peterc@gelato.unsw.edu.au> Signed-off-by: Tony Luck <tony.luck@intel.com>

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+376
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!
