Subject: [PATCH 4/5] parisc: Fix default stack size when COMPAT=n
Date: Wed, 8 Apr 2026 00:27:13 +0200 [thread overview]
Message-ID: <20260407222714.178861-4-deller@kernel.org> (raw)
In-Reply-To: <20260407222714.178861-1-deller@kernel.org>
From: Helge Deller <deller@gmx.de>
The CONFIG_STACK_MAX_DEFAULT_SIZE_MB config option does not exist
when CONFIG_COMPAT is disabled. Use default 1GB stack in this case.
