Subject: KVM: x86: remove ignored type attribute
Patch-mainline: v4.13-rc1
Git-commit: 8616abc253793345a245d026c7a0cc11fbc3abd8
References: bsc#1077761
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.
