Date: Mon, 1 Apr 2024 20:47:04 -0500 From: Haris Okanovic <harisokn@...zon.com> To: <linux-kernel@...r.kernel.org>, <linux-pm@...r.kernel.org>, <linux-assembly@...r.kernel.org> CC: <peterz@...radead.org>, Haris Okanovic <harisokn@...zon.com> Subject: [PATCH 1/3] arm64: Add TIF_POLLING_NRFLAG TIF_POLLING_NRFLAG was removed from arm64 as there were no polling idle states. Add back TIF_POLLING_NRFLAG in preparation for an arm64 cpuidle driver which supports polling.
