Subject: [PATCH AUTOSEL 4.14 7/7] hyperv/vmbus: include linux/bitops.h
Date: Mon, 25 Oct 2021 13:01:20 -0400 [thread overview]
Message-ID: <20211025170120.1394792-7-sashal@kernel.org> (raw)
In-Reply-To: <20211025170120.1394792-1-sashal@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
[ Upstream commit 8017c99680fa65e1e8d999df1583de476a187830 ]
On arm64 randconfig builds, hyperv sometimes fails with this
error:
In file included from drivers/hv/hv_trace.c:3:
In file included from drivers/hv/hyperv_vmbus.h:16:
In file included from arch/arm64/include/asm/sync_bitops.h:5:
arch/arm64/include/asm/bitops.h:11:2: error: only <linux/bitops.h> can be included directly
In file included from include/asm-generic/bitops/hweight.h:5:
include/asm-generic/bitops/arch_hweight.h:9:9: error: implicit declaration of function '__sw_hweight32' [-Werror,-Wimplicit-function-declaration]
include/asm-generic/bitops/atomic.h:17:7: error: implicit declaration of function 'BIT_WORD' [-Werror,-Wimplicit-function-declaration]
Include the correct header first.
