Message-ID: <20251121100044.282684-10-thuth@redhat.com>
Date: Fri, 21 Nov 2025 11:00:44 +0100

Subject: [PATCH v4 9/9] treewide: Stop defining __ASSEMBLY__ for assembler files
From: Thomas Huth <thuth@...hat.com>
All spots have been changed to __ASSEMBLER__ (i.e. the macro that
gets defined by the compiler), so we don't have to manually define
__ASSEMBLY__ now anymore.
Signed-off-by: Thomas Huth <thuth@...hat.com>
