From e0eeb4a21a3ca4b296220ce4449d8acef9de9049 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Benn=C3=A9e?= Date: Tue, 2 Aug 2016 18:27:33 +0100 Subject: cpus: pass CPUState to run_on_cpu helpers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CPUState is a fairly common pointer to pass to these helpers. This means if you need other arguments for the async_run_on_cpu case you end up having to do a g_malloc to stuff additional data into the routine. For the current users this isn't a massive deal but for MTTCG this gets cumbersome when the only other parameter is often an address. This adds the typedef run_on_cpu_func for helper functions which has an explicit CPUState * passed as the first parameter. All the users of run_on_cpu and async_run_on_cpu have had their helpers updated to use CPUState where available.
