From 0872098804b5f44bab91f80b6df55df32894fee3 Mon Sep 17 00:00:00 2001 From: Brian Gerst Date: Fri, 13 Mar 2020 15:51:34 -0400 Subject: x86/entry: Move max syscall number calculation to syscallhdr.sh Instead of using an array in asm-offsets to calculate the max syscall number, calculate it when writing out the syscall headers.
