pageflags: standardize comment inclusion in asm-offsets.h and fix MIPS

2008-04-28T15:58:21+00:00

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.

rename thread_info to stack

2007-05-09T19:30:56+00:00

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.

[MIPS] Add basic SMARTMIPS ASE support

2007-02-22T00:50:44+00:00

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.

[MIPS] signal32: no need to save c0_status register in setup_sigcontext32()

2007-02-10T22:38:47+00:00

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.
