Date: Thu, 28 Jan 2016 11:32:11 +0000 From: Suzuki K Poulose <suzuki.poulose@....com> To: linux-arm-kernel@...ts.infradead.org Cc: will.deacon@....com, catalin.marinas@....com, mark.rutland@....com, ynorov@...iumnetworks.com, linux-kernel@...r.kernel.org, Suzuki K Poulose <suzuki.poulose@....com> Subject: [PATCH 0/6] Support for systems without AArch32 state This series add checks to make sure that the AArch32 state is supported before we process the 32bit ID registers. Also checks the same for COMPAT binary execution. This series applies on top of 4.5-rc1 + Early CPU feature verification [1] + Handle sign bit for CPU Features [2], even though review doesn't require going through [1] & [2].
