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
precious blocks on an embedded system.

From eee16330c9de9adf7880cce9f1d32e13f89706bb Mon Sep 17 00:00:00 2001

Subject: MIPS: Add crash and kdump support
From: http://patchwork.linux-mips.org/patch/1025/
Hello folks,
Please find here MIPS crash and kdump patches.
This is patch set of 3 patches:
1. generic MIPS changes (kernel);
2. MIPS Cavium Octeon board kexec/kdump code (kernel);
3. Kexec user space MIPS changes.
Patches were tested on the latest linux-mips@ git kernel and the latest
kexec-tools git on Cavium Octeon 50xx board.
I also made the same code working on RMI XLR/XLS boards for both
mips32 and mips64 kernels.
Best regards,
Maxim Uvarov.
------
[ Zhangjin: Several trivial building failure has been fixed.
Note: the 2nd patch can not be cleanly applied, but may be a good
reference for the other board development:
+ MIPS Cavium Octeon board kexec,kdump support
http://patchwork.linux-mips.org/patch/1026/
And the 3rd patch has already been merged into the mainline kexec-tools:
+ some kexec MIPS improvements
http://patchwork.linux-mips.org/patch/1027/
kexec-tools is available here:
+ http://horms.net/projects/kexec/
git://git.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git

Subject: MIPS: Kexec: Enhance the support
Changes:
o Print more information in machine_kexec() for debugging
E.g. with this information, the kexec_start_address has been found
it was wrong with 64bit kernel / o32 kexec-tools. Which must be
fixed later.
o Link relocate_kernel.S to a section for future extension
This allows more functions can be added for the kexec relocation
part even written in C. to add code into that section, you just need
to mark your function or data with __kexec or
__attribute__((__section__(".__kexec.relocate")))
TODO:
1. Make 64bit kernel / o32|n32|64 kexec-tools works
Fix the user-space kexec-tools, seems the tool only work for 32bit
machine. So, we need to add 64bit support for it. The address of the
entry point(kexec_start_address) is wrong and make the "kexec -e" fail.
the real entry point must be read from the new kernel image by the
user-space kexec-tools, otherwise, it will not work. The above 64bit
support tested is 64bit kernel with o32 user-space kexec-tools. The root
cause may be the different definition of virt_to_phys() and
phys_to_virt() in the kexec-tools and kernel space for 64bit system /
o32 kernel.
Ref: http://www.linux-mips.org/archives/linux-mips/2009-08/msg00149.html
2. Pass the arguments from kexec-tools to the new kernel image
Please refer to: "MIPS: Loongson: Kexec: Pass parameters to new kernel"

Subject: MIPS: Get kernel parameters from kexec-tools
Before, we simply use the command lines from the original bootloader,
but it is not convenient. Now, we accept the kernel parameters from the
--command-line or --append option of the kexec-tools. But If not
--command-line or --apend option indicated, will fall back to use the
ones from the original bootloader.
