kzalloc() allocates contiguous memory. There is no guarantee that a
large contiguous region will be available. Since kernel memory tends to
fragment after some time, have you considered to use vmalloc() instead?

In SAM I found the following spelling "Peripheral" instead of
"Peripherial" (two occurrences). Although everyone will understand the
intention of the above comment, using the same spelling as in SAM helps
people who search through the source code using grep.
