Subject: [PATCH] KVM: x86: remove ignored type attribute
Date: Thu, 22 Jun 2017 21:41:19 -0700 [thread overview]
Message-ID: <20170623044120.6296-1-nick.desaulniers@gmail.com> (raw)
The macro insn_fetch marks the 'type' argument as having a specified
alignment. Type attributes can only be applied to structs, unions, or
enums, but insn_fetch is only ever invoked with integral types, so Clang
produces 19 -Wignored-attributes warnings for this source file.
