[ Upstream commit 169d1a4a2adb2c246396c56aa2f9eec3868546f1 ]
The extru instruction leaves the most significant 32 bits of the target register in an undefined state on PA 2.0 systems. Provide a macro to safely use extru on 32- and 64-bit machines.
As the macro is not used by subsequent 4.4 patches,
That's basically true, but in case we backport some patches later on, it's handy if it's already in.
I don't believe this is suitable for -stable.
Please note that I didn't added a backport-request in my original commit. I'm fine with any decision if it's either dropped or kept.
