Subject: allow page size to vary on arm
X-Git-Tag: v1.1.17~104
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=0a4a16d11cc263c3f32325f985b9ed94b04af79f;p=oweals%2Fmusl.git

allow page size to vary on arm

the ABI for arm was silently changed at some point to allow page sizes
other than 4k; traditional binaries built with only 4k-aligned offsets
between load segments cannot run on such systems, but newer binutils
versions use 64k offset alignment.

while larger page size is undesirable for various reasons, users have
encountered hardware and/or kernels that lock the page size to a
larger value, so follow the new ABI and allow it to vary.
