Subject: [PATCH 2/2] compiler.h: Include asm/rwonce.h under ARM64 and ALPHA to fix build errors
Date: Wed, 13 Jan 2021 18:57:33 +0800	[thread overview]
Message-ID: <1610535453-2352-3-git-send-email-yangtiezhu@loongson.cn> (raw)
In-Reply-To: <1610535453-2352-1-git-send-email-yangtiezhu@loongson.cn>

When make M=samples/bpf on the Loongson 3A3000 platform which
belongs to MIPS arch, there exists many similar build errors
about 'asm/rwonce.h' file not found, so include it only under
CONFIG_ARM64 and CONFIG_ALPHA due to it exists only in arm64
and alpha arch.
