Subject: [PATCH v3 01/10] arm64: mark (__)cpus_have_const_cap as __always_inline
Date: Tue, 23 Apr 2019 12:20:57 +0900 [thread overview]
Message-ID: <20190423032106.11960-2-yamada.masahiro@socionext.com> (raw)
In-Reply-To: <20190423032106.11960-1-yamada.masahiro@socionext.com>
This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common
place. We need to eliminate potential issues beforehand.
If it is enabled for arm64, the following errors are reported:
