From 529e502f05359cb3b95857bc349289f714614ac2 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Tue, 20 Oct 2020 17:37:13 -0700 Subject: [PATCH] x86: Separate system call tables into their own files. These tables take up a lot of space and obscure what's going on in the file around them. This change moves them into their own files (one for 32 bit and one for 64 bit). It also moves the x86 local definitions of some system calls into their own file, and creates a SConscript file for the linux subdirectory.
