From 020667d661f9be65167174d28a6eda7102f7293f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Cl=C3=A9ment=20L=C3=A9ger?= Date: Mon, 2 Jun 2025 21:39:15 +0200 Subject: [PATCH] riscv: process: use unsigned int instead of unsigned long for put_user() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The specification of prctl() for GET_UNALIGN_CTL states that the value is returned in an unsigned int * address passed as an unsigned long. Change the type to match that and avoid an unaligned access as well.
