From: Philippe Mathieu-Daudé Date: Tue, 21 Jan 2025 11:12:35 +0000 (+0100) Subject: cpus: Prefer cached CpuClass over CPU_GET_CLASS() macro X-Git-Tag: pull-xen-20250310~3^2~31 X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=30e76638eb35ffe88e95cca2b5af952c14dc336d;p=people%2Faperard%2Fqemu-dm.git cpus: Prefer cached CpuClass over CPU_GET_CLASS() macro CpuState caches its CPUClass since commit 6fbdff87062 ("cpu: cache CPUClass in CPUState for hot code paths"), use it.
