Subject: hw/arm/virt: Update comment about Multiprocessor Affinity Register
X-Git-Tag: v10.1.0-rc0~102^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ecb0cfb8a2b09fb0352b7adb83f18888be47a1cf;p=thirdparty%2Fqemu.git

hw/arm/virt: Update comment about Multiprocessor Affinity Register

Support on ARMv7 has been dropped in commit 82bf7ae84ce
("target/arm: Remove KVM support for 32-bit Arm hosts").
Update the comment in virt_cpu_mp_affinity() to avoid
mentioning it.
