-MIPS: allow disabling the kernel FPU emulator

-This patch allows turning off the in-kernel Algorithmics
-FPU emulator support, which allows one to save a couple of

+Subject: [RFC PATCH v4 2/2] MIPS: make FPU emulator optional\r
+Date: Mon, 7 Apr 2014 12:57:04 +0200\r
+Message-Id: <1396868224-252888-2-git-send-email-manuel.lauss@gmail.com>\r
+\r
+This small patch makes the MIPS FPU emulator optional. The kernel\r
+kills float-users on systems without a hardware FPU by sending a SIGILL.\r
+\r
+Disabling the emulator shrinks vmlinux by about 54kBytes (32bit,\r
+optimizing for size).\r
+\r
+Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com>\r
+---\r
+v4: rediffed because of patch 1/2, should now work with micromips as well\r
+v3: updated patch description with size savings.\r
+v2: incorporated changes suggested by Jonas Gorski\r
+ force the fpu emulator on for micromips: relocating the parts\r
+ of the mmips code in the emulator to other areas would be a\r
+ much larger change; I went the cheap route instead with this.\r

-+ This option allows building a kernel with or without the Algorithmics

++ This option lets you disable the built-in MIPS FPU (Coprocessor 1)
++ emulator, which handles floating-point instructions on processors
++ without a hardware FPU. It is generally a good idea to keep the
++ emulator built-in, unless you are perfectly sure you have a
++ complete soft-float environment. With the emulator disabled, all

-Subject: UBIFS: respect MS_SILENT mount flag
-
-When attempting to mount a non-ubifs formatted volume, lots of error
-messages (including a stack dump) are thrown to the kernel log even if
-the MS_SILENT mount flag is set.
-Fix this by introducing adding an additional state-variable in
-struct ubifs_info and suppress error messages in ubifs_read_node if
-MS_SILENT is set.
