Subject: [PATCH] linux/export: Ensure natural alignment of kcrctab array
Date: Thu, 28 Dec 2023 11:36:03 +0100	[thread overview]
Message-ID: <ZY1Pk61PP5HvLDag@p100> (raw)

The ___kcrctab section holds an array of 32-bit CRC values.
Add a .balign 4 to tell the linker the correct memory alignment.

Signed-off-by: Helge Deller <deller@gmx.de>
Fixes: f3304ecd7f06 ("linux/export: use inline assembler to populate symbol CRCs")
