From e43d24590329453a8fbf14850a3884b3919b74aa Mon Sep 17 00:00:00 2001 From: Alec Roelke Date: Wed, 13 Dec 2017 19:00:11 -0500 Subject: [PATCH] arch-riscv: Increase maximum stack size This patch increases the maximum stack size of RISC-V, which should help to reduce problems with programs that allocate large amounts of data on the stack or do many small allocations.
