- Subject: [PATCH roland/arm-dl-machine-clear-cache] Move Linuxism out of sysdeps/arm/dl-machine.h
A sysdeps/MACHINE file should not have anything that is OS-specific in it.
Ok? (Just merge my branch if you like, or I can do it on approval.)
Thanks,
Roland

* sysdeps/arm/dl-machine.h (CLEAR_CACHE): Don't define it.
Instead, #error if it's not defined.
* sysdeps/unix/sysv/linux/arm/dl-machine.h: New file.
