Most binaries don't actually depend on more than page alignment, but any binary can request it. Not honoring this was a bug.This became obvious when gdb reported Failed to read a valid object file image from memory when examining some vdso which are marked as needing more than page alignment.
Should we pick this one up for stable series too (and maybe a subsequent cleanup)? And/or maybe all the alignment reducing patches for vdsos? One or the other is apparently needed, but I'm not sure how really problematic this issue is. And you didn't Cc stable here for a reason, I guess :) For now I picked up the alignment change for arm vdso due to a subsequent change there (be8 & be32 split). What's left looks.. lonely :) What do you think? Thanks, /mjt
