[PATCH 0/3] ASID allocator fixes

[Marc Zyngier]

This patch series fixes a number of ASID allocator issues that have
been found while running in a virtualized environment (KVM).

The first one is rather critical, as it is pretty easy to trigger and
leads to userspace dying randomly in a VM.
The second one is more unlikely but may lead to memory corruption.
The last one makes the handling of erratum 798181 more robust.

For these reasons, I've added the "Cc: stable" tag.

They have all been tested on TC2 with 3.10-rc5. The patches are also
available in my tree:
