+Subject: [PATCH] target-ppc: fix bit extraction for FPBF and FPL
+Date: Thu, 15 Aug 2013 13:32:38 +0200
+Message-Id: <1376566358-8989-1-git-send-email-aurelien@aurel32.net>
+X-Mailer: git-send-email 1.7.10.4
+
+Bit extraction for the FP BF and L field of the MTFSFI and MTFSF
+instructions is wrong and doesn't match the reference manual (which
+explain the bit number in big endian format). It has been broken in
+commit 7d08d85645def18eac2a9d672c1868a35e0bcf79.
+
+This patch fixes this, which in turn fixes the problem reported by
+Khem Raj about the floor() function of libm.

+I don't know if we still have time to get this into 1.6, hence the Cc:
+to stable. In anycase it also needs to be fixed in 1.5.
