From bedf142b8bba4331ed93161292a4ce4f8cde7308 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Mon, 7 Nov 2005 21:12:08 +0000 Subject: [ARM] 3118/1: fix and reenable nwfpe extended precision emulation for big-endian Patch from Lennert Buytenhek nwfpe extended precision emulation used to be broken on big-endian and was therefore disabled. This patch fixes nwfpe so that it copies extended precision floats to/from userspace in the proper word order (similar to patch #2046, see the description of that patch for an explanation) and reenables the Kconfig option.
