From 4595f9620cda8a1e973588e743cf5f8436dd20c6 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Sat, 10 Jan 2009 21:58:09 -0800 Subject: x86: change flush_tlb_others to take a const struct cpumask Impact: reduce stack usage, use new cpumask API. This is made a little more tricky by uv_flush_tlb_others which actually alters its argument, for an IPI to be sent to the remaining cpus in the mask. I solve this by allocating a cpumask_var_t for this case and falling back to IPI should this fail. To eliminate temporaries in the caller, all flush_tlb_others implementations now do the this-cpu-elimination step themselves. Note also the curious "cpus_or(f->flush_cpumask, cpumask, f->flush_cpumask)" which has been there since pre-git and yet f->flush_cpumask is always zero at this point.

And CONFIG_PREEMPT is not enabled by default in the distribution that most UV owners will use. We could #ifdef CONFIG_PREEMPT the warning, but that is not good form. And there seems to be no suitable fix to in_atomic() when CONFIG_PREMPT is not on. As Ingo commented: > and we have no proper primitive to test for atomicity. (mainly > because we dont know about atomicity on a non-preempt kernel) So we drop the WARN_ON.
