[Qemu-devel] [PATCH 0/5] tcg-arm: LPAE: fix and extend xn control

From: Andrew Jones
Subject: [Qemu-devel] [PATCH 0/5] tcg-arm: LPAE: fix and extend xn control
Date: Thu, 12 Feb 2015 16:05:02 +0100

This series fixes and extends the determination of whether or
not an address is executable for LPAE translations. The main
patch is 4/5, and describes the details in its commit message.
Patches 1-3 prepare for the main patch, and patch 5/5 is a
code cleanup made possible by introducing a new helper function
with the main patch.

This is actually a second version of [1], now based on Peter's
recent translation regime support. However, as the series
has changed substantially, I'm not calling this 'v2'. I believe
I've addressed all of Peter's comments on that first posting in
this refresh though.

Tested by booting Linux on mach-virt with cortex-a15 and cortex-a57
(just up to 'Unable to mount root fs'), and also with a kvm-unit-tests
test. The curious can check out the unit test here [2].

Thanks in advance for reviews!
