Out of date warning?

Out of date warning?

[Gary Thomas]

Poky just presented me with this warning (on a new machine), when building for
an ARM (OMAP/3530) platform:

===================================================================================
$ bitbake omap-installer-image
Pseudo is not present but is required, building this first before the main build
ERROR:  Poky's config sanity checker detected a potential misconfiguration.
     Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
     Following is the list of potential problems / advisories:

     /proc/sys/vm/mmap_min_addr is not 0. This will cause problems with qemu so please fix the value (as root).

To fix this in later reboots, set vm.mmap_min_addr = 0 in /etc/sysctl.conf.
===================================================================================

I know this warning was in place because Qemu was used to run some
tasks, e.g. locale generation.  My impression is that this is no longer
the case, so do we still need this warning?

We have a bug tracking the issue:
http://bugzilla.pokylinux.org/show_bug.cgi?id=543

Most recent update indicates that there are still edge cases which
require this check to be in place, though possibly only when running
qemu for arm images?

Cheers,

Gary,

Most of this check has already removed except for ARM.
In theory, check for ARM should also be removed. But there is some 
corner case need to be tested, and I'll try them.

Pls. see
