From 7cd60e43a6def40ecb75deb8decc677995970d0b Mon Sep 17 00:00:00 2001 From: "Chang S. Bae" Date: Tue, 18 May 2021 13:03:15 -0700 Subject: [PATCH] uapi/auxvec: Define the aux vector AT_MINSIGSTKSZ Define AT_MINSIGSTKSZ in the generic uapi header. It is already used as generic ABI in glibc's generic elf.h, and this define will prevent future namespace conflicts. In particular, x86 is also using this generic definition. Signed-off-by: Chang S.
