Subject: [PATCH -tip 3/4] x86/idle: Remove unneeded delimiters from asm templates
Date: Wed, 2 Apr 2025 20:08:07 +0200 [thread overview]
Message-ID: <20250402180827.3762-3-ubizjak@gmail.com> (raw)
In-Reply-To: <20250402180827.3762-1-ubizjak@gmail.com>
Delimiters at the end of asm templates are not needed. Remove
them to make asm instruction length calculations more accurate.
