From 72d3ebb929de339f991fc49b58942d2d5ecdb753 Mon Sep 17 00:00:00 2001 From: Mathias Krause Date: Sun, 30 Dec 2018 13:36:00 +0100 Subject: kallsyms: lower alignment on ARM As mentioned in the info pages of gas, the '.align' pseudo op's interpretation of the alignment value is architecture specific. It might either be a byte value or taken to the power of two. On ARM it's actually the latter which leads to unnecessary large alignments of 16 bytes for 32 bit builds or 256 bytes for 64 bit builds. Fix this by switching to '.balign' instead which is consistent across all architectures.
