Subject: Fix determining PAGESIZE under Jython (#314)
X-Git-Tag: v0.27~29
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=478f61c3a590323144c9c1e0ef7b7254d9f82b6f;p=pyelftools.git

Fix determining PAGESIZE under Jython (#314)

Jython has neither `resource` nor `mmap`, therefore just use a
reasonable default.
