From 9a5d2cbe6a1623dadfd93007382b0d12d6bac894 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Tue, 5 May 2015 13:20:03 -0400 Subject: tile: set up initial stack top to honor STACK_TOP_DELTA For some reason this was never changed to match the rest of the code where we always initialize the kernel sp 64 bytes below the top of the page. This is generally harmless, but it does mean that if you do a dump_stack() early on in kernel boot you see a bogus warning about stack overrun.
