Re: earm(v5) not working on RPi

Using ktrace(1), I can see that the last thing done before the crash for
8.1 applications is a call to _lwp_ctl(2). This looks to be in
pthread__init().

Doing ktrace on hpcarm 7.1, _lwp_ctl() never gets called.

Do we have some optimization for reading pthread private data that is
different for armv7 and armv4 ?

We would need the kernel to allow both methods to work in order to be
able to run armv4 applications on an armv7 kernel.
