[PATCH 25/33] accel/tcg: Un-inline icount_exit_request() for clarity


From: Richard Henderson
Subject: [PATCH 25/33] accel/tcg: Un-inline icount_exit_request() for clarity
Date: Sun, 28 Jan 2024 14:42:05 +1000

From: Philippe Mathieu-Daudé <philmd@linaro.org>

Convert packed logic to dumb icount_exit_request() helper.
No functional change intended.
