Subject: s390/mm: remove unused tprot() function
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7190d84966b34de3892cd4eb8698a2229ceb8d82;p=linux.git

s390/mm: remove unused tprot() function

Since commit 461e0da7ddbb ("s390: remove broken hibernate / power
management support") there are no users of tprot() left. Remove
the function itself as well.
