The VMSA field of MMFR0 (bottom 4 bits) is incremented for each added feature.??PXN is supported if the value is >= 4 and LPAE is supported if it is >= 5.
In case a kernel with
CONFIG_ARM_LPAEdisabled is used on a processor that supports LPAE, we can still use PXN in short descriptors.??So check for >= 4 not == 4.Quoted 7 lines

If it's not in mainline already, than it probably isn't handled.

CatalinHi, Ben
It looks still not submitted yet. Could you send it to Russell's patch system?
http://www.arm.linux.org.uk/developer/patches/
I've never needed to use a web-based system to submit kernel patches before, and I'm not going to start now. ?Someone else can re-submit this if they want it.
Ben.

You don't have to... I just quote Catalin's recipe [1]
Quoted 15 lines
You can send patches as usual to patches at arm.linux.org.uk, just add
KernelVersion: v3.?? after the --- line in your patch (maybe this could be automate as well but I didn't bother).For series, because the arrival order is not guaranteed, I use the git alias below to trick it into sleeping 60s between patches:
ksend-rmk-patch = !git send-email --annotate --no-thread --suppress-cc=all --to-cmd='sleep 60 && echo patches at arm.linux.org.uk "#"'
For stgit, I have a dedicated template:
From: %(sender)s
To: patches at arm.linux.org.uk
Subject: %(prefix)s%(shortdescr)s
Quoted 6 lines
%(longdescr)s
PATCH FOLLOWS
KernelVersion:%(version)s
%(diff)sAnd there is always git pull request that Russell is happy with.
Does it work for you?

Thanks. Jungseung Lee has already re-submitted this patch, though.
