Subject: [PATCH v2 2/3] compiler_attributes.h: cleanups for GCC 4.9+
Date: Mon, 21 Jun 2021 16:18:21 -0700	[thread overview]
Message-ID: <20210621231822.2848305-3-ndesaulniers@google.com> (raw)
In-Reply-To: <20210621231822.2848305-1-ndesaulniers@google.com>

Since
commit 6ec4476ac825 ("Raise gcc version requirement to 4.9")
we no longer support building the kernel with GCC 4.8; drop the
preprocess checks for __GNUC_MINOR__ version. It's implied that if
__GNUC_MAJOR__ is 4, then the only supported version of __GNUC_MINOR__
left is 9.
