MIPS: Remove unused task_struct.trap_no field.

2010-08-05T12:26:30+00:00

It is initialized to zero and only ever read.  Remove it, and pass zero in
its place.

MIPS: Two-level pagetables for 64-bit kernels with 64KB pages.

2010-02-27T11:53:03+00:00

For 64-bit kernels with 64KB pages and two level page tables, there are
42 bits worth of virtual address space This is larger than the 40 bits of
virtual address space obtained with the default 4KB Page size and three
levels, so there are no draw backs for using two level tables with this
configuration.

MIPS: Use PAGE_SIZE in assembly instead of _PAGE_SIZE.

2009-09-17T18:07:48+00:00

Now that PAGE_SIZE is available to assembly directly, there is no need
to separately expose it as _PAGE_SIZE through asm-offsets.

In addition, remove _PAGE_SHIFT from asm-offsets, since it was never
needed, and is not used anywhere.

MIPS: Add hibernation support

2009-06-17T10:06:31+00:00

[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.]

mips: use kbuild.h instead of macros in asm-offsets.c

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.
