From a00e9e4319c2a8a8b166da028292de83190e39a4 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Tue, 18 Apr 2023 23:47:38 +0200 Subject: [PATCH] KVM: arm64: Use the bitmap API to allocate bitmaps Use bitmap_zalloc()/bitmap_free() instead of hand-writing them. It is less verbose and it improves the semantic.
