From a43b60cc78e25fddffec8b5401afab61f3dbd5c9 Mon Sep 17 00:00:00 2001 From: Simon Goldschmidt Date: Tue, 22 Oct 2019 21:29:48 +0200 Subject: [PATCH] arm: socfpga: gen5: fix ERR_PTR_OFFSET The default implementation of ERR_PTR/PTR_ERR maps errno values at the and of the address range (e.g. -EINVAL/-22 gets 0xFFFFFFEA). For socfpga gen5 SPL, this doesn't really work, as the heap is nearly at the end of the 32 bit address range. This patch adjusts the ERR_PTR_OFFSET to map errno values into the range of the Boot ROM, which should not be used for valid pointers.
