2008-10-16genirq: revert dynarrayThomas Gleixner
Revert the dynarray changes. They need more thought and polishing. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-10-16x86: move kstat_irqs from kstat to irq_descYinghai Lu
based on Eric's patch ... together mold it with dyn_array for irq_desc, will allcate kstat_irqs for nr_irq_desc alltogether if needed. -- at that point nr_cpus is known already. v2: make sure system without generic_hardirqs works they don't have irq_desc v3: fix merging v4: [mingo@elte.hu] fix typo [ mingo@elte.hu ] irq: build fix fix: arch/x86/xen/spinlock.c: In function 'xen_spin_lock_slow': arch/x86/xen/spinlock.c:90: error: 'struct kernel_stat' has no member named 'irqs' Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-16generic: sparse irqs: use irq_desc() together with dyn_array, instead of ↵Yinghai Lu
irq_desc[] add CONFIG_HAVE_SPARSE_IRQ to for use condensed array. Get rid of irq_desc[] array assumptions. Preallocate 32 irq_desc, and irq_desc() will try to get more. ( No change in functionality is expected anywhere, except the odd build failure where we missed a code site or where a crossing commit itroduces new irq_desc[] usage. ) v2: according to Eric, change get_irq_desc() to irq_desc() Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-08-14x86: resurrect proper handling of maxcpus= kernel option (v2)Max Krasnyansky
For some reason we had two parsers registered for maxcpus=. One in init/main.c and another in arch/x86/smpboot.c. So I nuked the one in arch/x86. Also 64-bit kernels used to handle maxcpus= as documented in Documentation/cpu-hotplug.txt. CPUs with 'id > maxcpus' are initialized but not booted. 32-bit version for some reason ignored them even though all the infrastructure for booting them later is there. In the current mainline both 64 and 32 bit versions are broken. This patch restores the correct behaviour. I've tested x86_64 version on 4- and 8- way Core2 and 2-way Opteron based machines. Various config combinations SMP, !SMP, CPU_HOTPLUG, !CPU_HOTPLUG. Booted with maxcpus=1 and maxcpus=4, etc. Everything is working as expected. So far we've received two reports from different people confirming that 32-bit version also works fine, both on dual core laptops and 16way server machines.
