Paolo, Radim,

Here's the KVM/ARM updates for 4.11-rc2. The usual bag of vgic
updates, making the memslot array large enough to handle guests with
tons of devices assigned to them, a tidying up of exception handling,
and a rather annoying TLB handling issue on VHE systems.

Please pull,

Thanks,

	M.

----------------------------------------------------------------
KVM/ARM updates for v4.11-rc2

vgic updates:
- Honour disabling the ITS
- Don't deadlock when deactivating own interrupts via MMIO

  many PCIe devices

General bug fixes:
- Gracefully handle exception generated with syndroms that
  the host doesn't understand
- Properly invalidate TLBs on VHE systems

Pulled, but what made you change the GPG key into a revoked one?

  # gpg: Signature made Thu 09 Mar 2017 10:36:07 AM CET
  # gpg:                using RSA key AB309C74B93B1EA1
  # gpg: Good signature from "Marc Zyngier <marc.zyngier@arm.com>"
  # gpg: WARNING: This key has been revoked by its owner!
  # gpg:          This could mean that the signature is forged.
  # gpg: reason for revocation: Key has been compromised
  # gpg: revocation comment: Revoked after kernel.org hacking
  # Primary key fingerprint: 6958 C9F2 233C 5E9D 6CCA  818A AB30 9C74 B93B 1EA1

Gahhh... New laptop, keyring restored from a backup containing the
revoked key, gpg-agent picking the revoked key as a default, idiot
sitting behind the keyboard not paying attention :-(. Now fixed.

Sorry about that.
