Subject: [PATCH 1/2] memblock tests: fix warning: "__ALIGN_KERNEL" redefined
Date: Thu, 14 Sep 2023 10:56:31 +0300	[thread overview]
Message-ID: <20230914075632.9515-2-rppt@kernel.org> (raw)
In-Reply-To: <20230914075632.9515-1-rppt@kernel.org>

From: "Mike Rapoport (IBM)" <rppt@kernel.org>

Building memblock tests produces the following warning:

cc -I. -I../../include -Wall -O2 -fsanitize=address -fsanitize=undefined -D CONFIG_PHYS_ADDR_T_64BIT   -c -o main.o main.c

Remove definitions of __ALIGN_KERNEL and __ALIGN_KERNEL_MASK from
tools/include/linux/mm.h to fix it.
