From aaeca98456431a8d9382ecf48ac4843e252c07b3 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 7 Nov 2022 17:07:47 +0000 Subject: [PATCH] arm64/fpsimd: Make kernel_neon_ API _GPL Currently for reasons lost in the mists of time the kernel_neon_ APIs are EXPORT_SYMBOL() but the general policy for floating point usage is that it should be GPL only given the non-standard runtime environment that holds while it is in use and PCS impacts when code is compiled for FP usage. Given the limited existing deployment of non-GPL modules for arm64 and the fact that other architectures like x86 already make their equivalent functions GPL only this is not expected to be disruptive to existing users.
