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. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
