Subject: [PATCH v5 14/34] vdso/datapage: Remove inclusion of gettimeofday.h
Date: Thu, 06 Nov 2025 11:02:07 +0100	[thread overview]
Message-ID: <20251106-vdso-sparc64-generic-2-v5-14-97ff2b6542f7@linutronix.de> (raw)
In-Reply-To: <20251106-vdso-sparc64-generic-2-v5-0-97ff2b6542f7@linutronix.de>

vdso/datapage.h is useful without pulling in the architecture-specific
gettimeofday() helpers.

Move the include to the only users which needs it.
