Date: Mon, 9 Nov 2015 17:31:09 -0800 From: Palmer Dabbelt <palmer@...belt.com> To: peterz@...radead.org Cc: Palmer Dabbelt <palmer@...belt.com> Subject: [PATCH 12/14] Remove AT_VECTOR_SIZE_ARCH on x86 It looks like there aren't actually users of this macro anywhere: * The kernel doesn't use it on x86 because we don't suppor ELF FDPIC. * The only Google results point to LMKL patches, both the one that wrote this (from 2010) and my patch to hide it behind __KERNEL__. * I grep'd through all the source tarballs on my machine, and the only packages that matched were the kernel and crui (which copied a PPC kernel header). Since I'm not sure how to actually provide the right answer (if I understand correctly, CONFIG_IA32_EMULATION is not __i386__), the only thing I can think of to do is to just remove the definition.
