Subject: [PATCH 11/23] MIPS: ptrace: Use USER_REGSET_NOTE_TYPE() to specify regset note names
Date: Tue, 1 Jul 2025 14:56:04 +0100 [thread overview]
Message-ID: <20250701135616.29630-12-Dave.Martin@arm.com> (raw)
In-Reply-To: <20250701135616.29630-1-Dave.Martin@arm.com>
Instead of having the core code guess the note name for each regset,
use USER_REGSET_NOTE_TYPE() to pick the correct name from elf.h.
