6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: John Ogness <john.ogness@xxxxxxxxxxxxx> [ Upstream commit 0ab7cdd00491b532591ef065be706301de7e448f ] Currently @suppress_panic_printk is checked along with non-matching @panic_cpu and current CPU. This works because @suppress_panic_printk is only set when panic_in_progress() is true. Rather than relying on the @suppress_panic_printk semantics, use the concise helper function other_cpu_in_progress(). The helper function exists to avoid open coding such tests.
