Date: Sat, 29 Aug 2015 11:20:21 -0400 From: Brian Gerst <brgerst@...il.com> To: x86@...nel.org, linux-kernel@...r.kernel.org Cc: Ingo Molnar <mingo@...nel.org>, "H. Peter Anvin" <hpa@...or.com>, Denys Vlasenko <dvlasenk@...hat.com>, Andy Lutomirski <luto@...capital.net>, Linus Torvalds <torvalds@...ux-foundation.org> Subject: [PATCH 2/7] x86/vdso32: Remove VDSO32_vsyscall_eh_frame_size This symbol and the padding are unnecessary since we no longer rely on the symbols being exactly the same in each variant of the vdso32.
