From 53d7854beaf2dd11c793ffadd571488e6772b6da Mon Sep 17 00:00:00 2001 From: maximilian attems Date: Wed, 30 Jul 2008 11:46:32 +0200 Subject: [PATCH] use getpagesize() getpagesize() is said to be more portable than sysconf(_SC_PAGESIZE) to anything Linux. this patch helps klibc porting effort as the sysconf multiplex API is not supported there. also remove comment of the switch to sysconf in mkswap.c.
