On the 34K the redundant cache operations were causing excessive stalls
resulting in realtime code running on the second VPE missing its deadline.
For all other platforms this patch is just a significant performance
improvment as illustrated by below benchmark numbers.

Include the host architecture's ptrace-abi.h instead of ptrace.h.
There was some cpp mangling of names around the ptrace.h include to avoid
symbol clashes between UML and the host architecture. Most of these can go
away. The exception is struct pt_regs, which is convenient to have in
userspace, but must be renamed in order that UML can define its own.
ptrace-x86_64.h needed to have some now-obsolete cpp cruft and a declaration
removed.

The use of SEGMENT_RPL_MASK in the i386 ptrace.h introduced by
x86-allow-a-kernel-to-not-be-in-ring-0.patch broke the UML build, as UML
includes the underlying architecture's ptrace.h, but has no easy access to the
x86 segment definitions.
Rather than kludging around this, as in the past, this patch splits the
userspace-usable parts, which are the bits that UML needs, of ptrace.h into
ptrace-abi.h, which is included back into ptrace.h. Thus, there is no net
effect on i386.
As a side-effect, this creates a ptrace header which is close to being usable
in /usr/include.
x86_64 is also treated in this way for consistency. There was some trailing
whitespace there, which is cleaned up.

The KSTK_* macros used an inordinate amount of stack. In order to overcome
an impedance mismatch between their interface, which just returns a single
register value, and the interface of get_thread_regs, which took a full
pt_regs, the implementation created an on-stack pt_regs, filled it in, and
returned one field. do_task_stat calls KSTK_* twice, resulting in two
local pt_regs, blowing out the stack.
This patch changes the interface (and name) of get_thread_regs to just
return a single register from a jmp_buf.
The include of archsetjmp.h" in registers.h to get the definition of
jmp_buf exposed a bogus include of <setjmp.h> in start_up.c. <setjmp.h>
shouldn't be used anywhere any more since UML uses the klibc
setjmp/longjmp.

Make swsusp use memory bitmaps to store its internal information during the
resume phase of the suspend-resume cycle.
If the pfns of saveable pages are saved during the suspend phase instead of
the kernel virtual addresses of these pages, we can use them during the resume
phase directly to set the corresponding bits in a memory bitmap. Then, this
bitmap is used to mark the page frames corresponding to the pages that were
saveable before the suspend (aka "unsafe" page frames).
Next, we allocate as many page frames as needed to store the entire suspend
image and make sure that there will be some extra free "safe" page frames for
the list of PBEs constructed later. Subsequently, the image is loaded and, if
possible, the data loaded from it are written into their "original" page
frames (ie. the ones they had occupied before the suspend).
The image data that cannot be written into their "original" page frames are
loaded into "safe" page frames and their "original" kernel virtual addresses,
as well as the addresses of the "safe" pages containing their copies, are
stored in a list of PBEs. Finally, the list of PBEs is used to copy the
remaining image data into their "original" page frames (this is done
atomically, by the architecture-dependent parts of swsusp).

The current suspend code has to be run on one CPU, so we use the CPU
hotplug to take the non-boot CPUs offline on SMP machines. However, we
should also make sure that these CPUs will not be enabled by someone else
after we have disabled them.
The functions disable_nonboot_cpus() and enable_nonboot_cpus() are moved to
kernel/cpu.c, because they now refer to some stuff in there that should
better be static. Also it's better if disable_nonboot_cpus() returns an
error instead of panicking if something goes wrong, and
enable_nonboot_cpus() has no reason to panic(), because the CPUs may have
been enabled by the userland before it tries to take them online.

On x86_64 machines with more than 2 GB of RAM there are large memory gaps
(with no corresponding kernel virtual addresses) and reserved memory
regions between areas of usable physical RAM. Moreover, if CONFIG_FLATMEM
is set, they appear within the normal zone. swsusp should not try to save
them, so the corresponding page structs have to be marked as 'nosave'.

Implement async reads for swsusp resuming.
Crufty old PIII testbox:
15.7 MB/s -> 20.3 MB/s
Sony Vaio:
14.6 MB/s -> 33.3 MB/s
I didn't implement the post-resume bio_set_pages_dirty(). I don't really
understand why resume needs to run set_page_dirty() against these pages.
It might be a worry that this code modifies PG_Uptodate, PG_Error and
PG_Locked against the image pages. Can this possibly affect the resumed-into
kernel? Hopefully not, if we're atomically restoring its mem_map?

I've come across some problems with the assembly version of the ELFNOTE
macro currently in -mm. (in
x86-put-note-sections-into-a-pt_note-segment-in-vmlinux.patch)
The first is that older gas does not support :varargs in .macro
definitions (in my testing 2.17 does while 2.15 does not, I don't know
when it became supported). The Changes file says binutils >= 2.12 so I
think we need to avoid using it. There are no other uses in mainline or
-mm. Old gas appears to just ignore it so you get "too many arguments"
type errors.
Secondly it seems that passing strings as arguments to assembler macros
is broken without varargs. It looks like they get unquoted or each
character is treated as a separate argument or something and this causes
all manner of grief. I think this is because of the use of -traditional
when compiling assembly files.
Therefore I have translated the assembler macro into a pre-processor
macro.
I added the desctype as a separate argument instead of including it with
the descdata as the previous version did since -traditional means the
ELFNOTE definition after the #else needs to have the same number of
arguments (I think so anyway, the -traditional CPP semantics are pretty
fscking strange!).
With this patch I am able to define elfnotes in assembly like this with
both old and new assemblers.
ELFNOTE(Xen, XEN_ELFNOTE_GUEST_OS, .asciz, "linux")
ELFNOTE(Xen, XEN_ELFNOTE_GUEST_VERSION, .asciz, "2.6")
ELFNOTE(Xen, XEN_ELFNOTE_XEN_VERSION, .asciz, "xen-3.0")
ELFNOTE(Xen, XEN_ELFNOTE_VIRT_BASE, .long, __PAGE_OFFSET)
Which seems reasonable enough.

This patch will pack any .note.* section into a PT_NOTE segment in the output
file.
To do this, we tell ld that we need a PT_NOTE segment. This requires us to
start explicitly mapping sections to segments, so we also need to explicitly
create PT_LOAD segments for text and data, and map the sections to them
appropriately. Fortunately, each section will default to its previous
section's segment, so it doesn't take many changes to vmlinux.lds.S.
This only changes i386 for now, but I presume the corresponding changes for
other architectures will be as simple.
This change also adds <linux/elfnote.h>, which defines C and Assembler macros
for actually creating ELF notes.

This patchset adds the necessary drivers and infrastructure to access the
external flash on the ATSTK1000 board through the MTD subsystem. With this
stuff in place, it will be possible to use a jffs2 filesystem stored in the
external flash as a root filesystem. It might also be possible to update the
boot loader if you drop the write protection of partition 0.
As suggested by David Woodhouse, I reworked the patches to use the physmap
driver instead of introducing a separate mapping driver for the ATSTK1000.
I've also cleaned up the hsmc header by removing useless comments and
converting spaces to tabs (my headerfile generator needs some work.)
Unfortunately, I couldn't unlock the flash in fixup_use_atmel_lock because the
erase regions hadn't been set up yet, so I had to do it from cfi_amdstd_setup
instead.
This patch:
This adds a simple API for configuring the static memory controller along with

This adds support for the Atmel AVR32 architecture as well as the AT32AP7000
CPU and the AT32STK1000 development board.
AVR32 is a new high-performance 32-bit RISC microprocessor core, designed for
cost-sensitive embedded applications, with particular emphasis on low power
consumption and high code density. The AVR32 architecture is not binary
compatible with earlier 8-bit AVR architectures.
The AVR32 architecture, including the instruction set, is described by the
AVR32 Architecture Manual, available from
http://www.atmel.com/dyn/resources/prod_documents/doc32000.pdf
The Atmel AT32AP7000 is the first CPU implementing the AVR32 architecture. It
features a 7-stage pipeline, 16KB instruction and data caches and a full
Memory Management Unit. It also comes with a large set of integrated
peripherals, many of which are shared with the AT91 ARM-based controllers from
Atmel.
Full data sheet is available from
http://www.atmel.com/dyn/resources/prod_documents/doc32003.pdf
while the CPU core implementation including caches and MMU is documented by
the AVR32 AP Technical Reference, available from
http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf
Information about the AT32STK1000 development board can be found at
http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3918
including a BSP CD image with an earlier version of this patch, development
tools (binaries and source/patches) and a root filesystem image suitable for
booting from SD card.
Alternatively, there's a preliminary "getting started" guide available at
http://avr32linux.org/twiki/bin/view/Main/GettingStarted which provides links
to the sources and patches you will need in order to set up a cross-compiling
environment for avr32-linux.
This patch, as well as the other patches included with the BSP and the
toolchain patches, is actively supported by Atmel Corporation.

There are many places where we need to determine the node of a zone.
Currently we use a difficult to read sequence of pointer dereferencing.
Put that into an inline function and use throughout VM. Maybe we can find
a way to optimize the lookup in the future.
