Subject: [RFC PATCH 1/5] powerpc: Add bitmasks for D-form instruction fields
Date: Mon,  4 Feb 2019 09:48:35 +0530	[thread overview]
Message-ID: <b07666d48fb89f80a86a18e498c7e1eac9a64aa1.1549253769.git.sandipan@linux.ibm.com> (raw)
In-Reply-To: <cover.1549253769.git.sandipan@linux.ibm.com>

This adds the bitmask definitions of D, SI and UI fields
found in D-form instructions.
