Subject: utils: don't depend on PAGE_SIZE
X-Git-Tag: 0.8.4~61
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b6b10b1cbcf9f7d42a3c4b73dadbd645deca7a62;p=thirdparty%2Fplymouth.git

utils: don't depend on PAGE_SIZE

It's not defined for all architectures.

We don't really need the page size anyway, we just need a reasonably
large value.
