Julien Grall 0b61f2c0f3 arm/xen: Enable user access to the kernel before issuing a privcmd call ... When Xen is copying data to/from the guest it will check if the kernel has the right to do the access. If not, the hypercall will return an error. After the commit a5e090acbf "ARM: software-based privileged-no-access support", the kernel can't access any longer the user space by default. This will result to fail on every hypercall made by the userspace (i.e via privcmd). We have to enable the userspace access and then restore the correct permission every time the privcmd is used to made an hypercall. I didn't find generic helpers to do a these operations, so the change is only arm32 specific.
