this should all be a single patch, because the cpus4096 tree does not build on these arhitectures right now.
in fact, i think i'll rebase the whole lineup (so no need to resend - i'll squash these fixes together), because this is how it looks like right now:
28e0886: xen: fix too early kmalloc call 92296c6: cpumask, irq: non-x86 build failures 542d865: kstat: modify kstat_irqs_legacy to be variable sized 9332fcc: irq: initialize nr_irqs based on nr_cpu_ids 0fa0ebb: irq: allocate irq_desc_ptrs array based on nr_irqs e2f4d06: irq: use WARN() instead of WARN_ON(). 9594949: irq: change references from NR_IRQS to nr_irqs c7a3589: Xen: reduce memory required for cpu_evtchn_mask d38b223: cpumask: reduce stack usage in find_lowest_rq c90e785: cpumask: use cpumask_var_t in dcdbas.c f9b9056: x86: reduce stack usage in init_intel_cacheinfo a1c33bb: x86: cleanup remaining cpumask_t code in mce_amd_64.c 0e21990: SGI UV cpumask: use static temp cpumask in flush_tlb 4595f96: x86: change flush_tlb_others to take a const struct cpumask 802bf93: cpumask: fix bug in use cpumask_var_t in irq_desc 651f811: cpumask: convert other misc kernel functions 2f8975f: cpumask: convert drivers/net/sfc f7df8ed: cpumask: convert misc driver functions fbd59a8: cpumask: Use topology_core_cpumask()/topology_thread_cpumask() 7f7ace0: cpumask: update irq_desc to use cpumask_var_t
those architectures break with the first patch: 7f7ace0. That's bisection breakage window of about 20 commits - too big and we want to avoid it if we can (and we still can).
