Hi Rob,

sorry for the long delay. In general, the patch looks OK, I only have
two remarks:


> + -e 's/(^|[ \t])(inline|asm|volatile)([ \t(]|$)/\1__\2__\3/g' \

This regexp does not match the 'volatile' in

#define XVMCLOCKPTR(saPriv,lockNo) \
((volatile struct drm_hw_lock *)(((((unsigned long) (saPriv)->XvMCLockArea) + \
(VIA_MAX_CACHELINE_SIZE - 1)) & \
~(VIA_MAX_CACHELINE_SIZE - 1)) + \
VIA_MAX_CACHELINE_SIZE*(lockNo)))

in include/uapi/drm/via_drm.h.

You are not passing $(SRCARCH) to the shell script. This seems OK, as
the list of files changes if needed, but the change should be mentioned
in the changelog.

Thanks,
Michal
