[PATCH 01/31] x86/asm-offsets: Move TSS_sp0 and TSS_sp1 to asm-offsets.c
From: Joerg Roedel
Date: Fri Feb 09 2018 - 04:26:04 EST
From: Joerg Roedel <jroedel@xxxxxxx>
These offsets will be used in 32 bit assembly code as well,
so make them available for all of x86 code.
Signed-off-by: Joerg Roedel <jroedel@xxxxxxx>
