irq_work: Make irq_work_queue() NMI-safe again
Someone carelessly put NMI unsafe code in irq_work_queue(), breaking just about every single user. Also, someone has a terrible comment style. Fixes: e2b5bcf9f5ba ("irq_work: record irq_work_queue() call stack") Reported-by: Alexander Shishkin <alexander.shishkin@linux.intel.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lkml.kernel.org/r/YL+uBq8LzXXZsYVf@hirez.programming.kicks-ass.net
