Subject: kvm: x86: increase user memory slots to 509
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1d4e7e3c0bca747d0fc54069a6ab8393349431c0;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

kvm: x86: increase user memory slots to 509

With the 3 private slots, this gives us 512 slots total.
Motivation for this is in addition to assigned devices
support more memory hotplug slots, where 1 slot is
used by a hotplugged memory stick.
It will allow to support upto 256 hotplug memory
slots and leave 253 slots for assigned devices and
other devices that use them.
