riscv: Fix crashes with large or frequent mmaps
This patch fixes a bug where increasing the mmap region too much causes it to run into already-allocated memory, which causes gem5 to fail an assertion. Previously, the stack was incorrectly set up such that the end of the mmap region and the top of the stack were the same address and both would grow downward. With this patch, the top of the stack has been separated from the end of mmap and moved up, and the mmap region now grows upward instead of downward. [Rebase to master branch and remove dependencies.] Change-Id: I7271ff478fff2994f918bc5003a6139b9ba6a520 Reviewed-on: https://gem5-review.googlesource.com/2680 Maintainer: Alec Roelke <ar4jc@virginia.edu> Reviewed-by: Jason Lowe-Power <jason@lowepower.com>
