Subject: [RFC PATCH PoC 11/11] x86/boot: Get rid of the .head.text section
Date: Wed, 23 Apr 2025 13:10:00 +0200	[thread overview]
Message-ID: <20250423110948.1103030-24-ardb+git@google.com> (raw)
In-Reply-To: <20250423110948.1103030-13-ardb+git@google.com>

From: Ard Biesheuvel <ardb@kernel.org>

The .head.text section is now empty, so it can be dropped from the
linker script.
