Subject: [PULL] KVM/ARM updates for Linux 4.8, take #1
Date: Fri, 22 Jul 2016 18:28:17 +0100 [thread overview]
Message-ID: <1469208552-4155-1-git-send-email-marc.zyngier@arm.com> (raw)
Paolo, Radim,
Please find below the first batch of 4.8 updates for KVM/ARM. Biggest
feature is the long awaited GICv3 ITS emulation, allowing MSIs to be
delivered into guests running on GICv3 HW. The other big feature is
the removal of the old vgic implementation. Less visible is the revamp
of the way we deal with the HYP initialization (by keeping an idmap
around), and making HYP page tables honor the kernel's own protection.
This may generate a few conflicts, all of which have been seen in
-next. 3 which are KVM specific (and pretty easy to resolve), and
another one in include/irqchip/arm-gic-v3.h. They should be resolved
as in -next.
Please pull!
M.
