Evaluated every variable that lives in .data (and globals in .rodata) in the kernel modules, and constified/eliminated/localised them appropriately. This means that all read-only data is now actually read-only data, and, if possible, at file scope. A lot of previously- global-symbols became inlinable (and inlined!) constants. Probably not in a big Wowee Performance Moment, but hey. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Ahelenia Ziemiańska <nabijaczleweli@nabijaczleweli.xyz> Closes #12899
