Date: Mon, 16 Mar 2015 17:32:21 +0100 From: Alexander Graf <agraf@...e.de> To: linux-arm-kernel@...ts.infradead.org Cc: schwab@...e.de, arnd@...db.de, will.deacon@....com, Catalin.Marinas@....com, matz@...e.de, linux-kernel@...r.kernel.org, dmueller@...e.com Subject: [PATCH 0/2] arm64: Allow AArch32 on arm64 with 64k PAGE_SIZE With binutils 2.25 the default alignment for 32bit arm sections changed to have everything 64k aligned. Armv7 binaries built with this binutils version run successfully on an arm64 system with this patch set applied. This provides the best of both worlds for some users. You get less page faults, but can still run legacy broken code that might not be 64bit safe yet. If you want to give this a try, you obviously need user space that was compiled with 64k constraints fulfilled.
