Subject: [PATCH 1/2] x86/sgx: Revert using BIT() to define ENCLS_FAULT_FLAG
Date: Mon, 7 Oct 2019 21:12:25 -0700 [thread overview]
Message-ID: <20191008041226.2974-2-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20191008041226.2974-1-sean.j.christopherson@intel.com>
ENCLS_FAULT_FLAG is run through __stringify() in the ENCLS asm helpers,
the build fails miserably if its defined via BIT().
