Subject: [PATCH v2 1/2] include/linux/unaligned.h: remove deprecated __get_unaligned_cpuX() helpers
Date: Thu, 29 Oct 2026 10:17:35 +0100	[thread overview]
Message-ID: <20261029091736.28742-2-julian@outer-limits.org> (raw)
In-Reply-To: <20261029091736.28742-1-julian@outer-limits.org>

The __get_unaligned_cpu16/32/64() and __put_unaligned_cpu16/32/64()
helpers are deprecated and all users have been converted to the more
generic get_unaligned() and put_unaligned(). So, remove
linux/unaligned/packed_struct.h, and drop its inclusion from
linux/unaligned.h.
