Subject: x86/devicetable: Move x86 specific macro out of generic code
To: stable@xxxxxxxxxxxxxxx
Cc: x86@xxxxxxxxxx, kvm@xxxxxxxxxxxxxxx, bp@xxxxxxxxx, pbonzini@xxxxxxxxxx, peterz@xxxxxxxxxxxxx, jpoimboe@xxxxxxxxxx
Message-ID: <20221003131038.12645-4-cascardo@xxxxxxxxxxxxx>
From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>
commit ba5bade4cc0d2013cdf5634dae554693c968a090 upstream.
There is no reason that this gunk is in a generic header file. The wildcard
defines need to stay as they are required by file2alias.
