| |
While reviewing arch/x86/configs/xen.config, I noticed the following note in this file:
'# depends on MEMORY_HOTPLUG, arm64 doesn't enable this yet, '# move to generic config if it ever does. CONFIG_XEN_BALLOON_MEMORY_HOTPLUG=y
Commit 6c6685055a28 ("kconfig: add xenconfig defconfig helper") in June 2015 adds this note. Fortunately, commit 4ab215061554 ("arm64: Add memory hotplug support") from December 2018 adds the memory hotplug in arm64, so the precondition of this note above is now met.
Move setting the config XEN_BALLOON_MEMORY_HOTPLUG into the generic xen.config now.
