Herbert Xu f139cfa7cd crypto: tcrypt - Avoid using contiguous pages 
If tcrypt is to be used as a run-time integrity test, it needs to be
more resilient in a hostile environment.  For a start allocating 32K
of physically contiguous memory is definitely out.

This patch teaches it to use separate pages instead.
