[PATCH] selftests: PAGE_SIZE may not be defined

[Thierry Fauck ( thierry @ linux.vnet.ibm.com )]

Hi Ben,

The following patch seems relevant for Ubuntu and Debian distro testing.
I know it's minor but I need to know if you do you care about it or sif
I should remove it from the bugs info.

Thanks

Best regards
Thierry

Subject: [PATCH] selftests: PAGE_SIZE may not be defined

Some systems have a dynamic PAGE_SIZE value and do not add a definition
for PAGE_SIZE. This value will have to be retrieved using getpagesize()
or sysconf().
