2009-06-17MIPS: Add hibernation supportWu Zhangjin
[Ralf: SMP support requires CPU hotplugging which MIPS currently doesn't support. As implemented in this patch cache and tlb flushing will also be invoked with interrupts disabled so smp_call_function() will blow up in charming ways. So limit to !SMP.] Reviewed-by: Pavel Machek <pavel@ucw.cz> Reviewed-by: Yan Hua <yanh@lemote.com> Reviewed-by: Arnaud Patard <apatard@mandriva.com> Reviewed-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Wu Zhangjin <wuzj@lemote.com> Signed-off-by: Hu Hongbing <huhb@lemote.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2008-04-28pageflags: standardize comment inclusion in asm-offsets.h and fix MIPSChristoph Lameter
Add the ability to pass comments into asm-offsets.h by generating asm output like -># comment line Mips needs this feature to preserve the comments that are in asm-mips/asm-offsets.h right now. Then remove the special handling for mips from Kbuild and convert mips to use the new string to include the comments.

2007-05-09rename thread_info to stackRoman Zippel
This finally renames the thread_info field in task structure to stack, so that the assumptions about this field are gone and archs have more freedom about placing the thread_info structure. Nonbroken archs which have a proper thread pointer can do the access to both current thread and task structure via a single pointer. It'll allow for a few more cleanups of the fork code, from which e.g. ia64 could benefit.

2007-02-22[MIPS] Add basic SMARTMIPS ASE supportFranck Bui-Huu
This patch adds trivial support for SMARTMIPS extension. This extension is currently implemented by 4KS[CD] CPUs. Basically it saves/restores ACX register, which is part of the SMARTMIPS ASE, when needed. This patch does *not* add any support for Smartmips MMU features. Futhermore this patch does not add explicit support for 4KS[CD] CPUs since they are respectively mips32 and mips32r2 compliant. So with the current processor configuration, a platform that has such CPUs needs to select both configs: CPU_HAS_SMARTMIPS SYS_HAS_CPU_MIPS32_R[12] This is due to the processor configuration which is mixing up all the architecture variants and the processor types. The drawback of this, is that we currently pass '-march=mips32' option to gcc when building a kernel instead of '-march=4ksc' for 4KSC case. This can lead to a kernel image a little bit bigger than required. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-02-10[MIPS] signal32: no need to save c0_status register in setup_sigcontext32()Franck Bui-Huu
All the information in the MIPS c0_status register is priviledged. Nothing that would constitute part of the thread context. The one flag one could possibly argument about might be c0_status.fr but none of the ABIs or tools or application software can make use of it. So for consistency with restore_sigcontext32(), which does not restore c0_status register, this patch remove the saving part.
