MIPS: Implement __read_mostly

2011-01-18T18:30:28Z

Just do what everyone else is doing by placing __read_mostly things in the .data.read_mostly section. mips_io_port_base can not be read-only (const) and writable (__read_mostly) at the same time. One of them has to go, so I chose to eliminate the __read_mostly. It will still get stuck in a portion of memory that is not adjacent to things that are written, and thus not be on a dirty cache line, for whatever that is worth.

MIPS: nofpu and nodsp only affect CPU0

2010-05-21T20:31:17Z

The "nofpu" and "nodsp" kernel command line options currently do not affect CPUs that are brought online later in the boot process or hotplugged at runtime. It is desirable to apply the nofpu/nodsp options to all CPUs in the system, so that surprising results are not seen when a process migrates from one CPU to another. [Ralf: Moved definitions of mips_fpu_disabled, fpu_disable, mips_dsp_disabled and dsp_disable from setup.c to cpu-probe.c to allow making mips_fpu_disabled and mips_dsp_disabled static.] Signed-off-by: Kevin Cernekee Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: http://patchwork.linux-mips.org/patch/1169/ Signed-off-by: Ralf Baechle

MIPS: Fix and enhance built-in kernel command line

2009-12-17T01:57:35Z

Currently, MIPS kernels silently overwrite kernel command-line parameters hardcoded in CONFIG_CMDLINE by the ones received from firmware. Therefore, using firmware remains the only reliable method to transfer the command-line parameters, which is not always desirable or convenient, and the CONFIG_CMDLINE option is thereby effectively rendered useless. This patch fixes the problem described above and introduces a more flexible scheme of handling the kernel command line, in a manner identical to what is currently used for x86. The default behavior, i.e. when CONFIG_CMDLINE_BOOL is not defined, retains the existing semantics, and firmware command-line arguments override the hardcoded ones. [Ralf: I fixed up all the defconfig files so the stay unaffected by this change.] Signed-off-by: Dmitri Vorobiev Cc: linux-mips@linux-mips.org Patchwork: http://patchwork.linux-mips.org/patch/689/ Signed-off-by: Ralf Baechle

Addinitrd has been superseded by initramfs ages ago. Signed-off-by: Ralf Baechle

MIPS: Replace all usages of CL_SIZE by COMMAND_LINE_SIZE

2009-12-17T01:56:56Z

The MIPS-specific macro CL_SIZE is merely aliasing the macro COMMAND_LINE_SIZE. Other architectures use the latter; also, COMMAND_LINE_SIZE is documented in kernel-parameters.txt, so let's use it, and remove the alias. Signed-off-by: Dmitri Vorobiev Signed-off-by: Ralf Baechle
