[-- Attachment #1: x86-unify-page_h.patch --]
[-- Type: text/plain, Size: 23674 bytes --]
Unify common definitions in page*.h. To simplify other code, I added
typedefs for the value of pte/pmd/pud/pgd values, so they can be used
symbolically elsewhere without needing to have lots of 32/64/PAE
tests.
Also, add PAGETABLE_LEVELS define so that other definitions can test
for it directly rather than using indirect 32/64/PAE tests.

[-- Attachment #1: x86-unify-pgtable_h.patch --]
[-- Type: text/plain, Size: 40902 bytes --]
All x86 modes and architectures have very similar pagetable
structures: the page flags, the accessors for testing/setting them,
and the combinations of page flags used for kernel and usermode
mappings are all the same. The main difference is between 32 and
64-bit pagetable entries, with the latter supporting the NX bit.
The most significant difference between the modes/architectures is the
number of levels in the pagetable (4 for 64-bit, 3 for 32-bit/PAE, 2
for non-PAE 32-bit). This accounts for the remaining code in the
various mode-specific headers.
I've tried to avoid changing formatting as much as possible, so that
the code motion is more obvious. A subsequent patch will clean things
up in place.

Is set_pte() really supposed to be used here? pte_val() and __pte()
are already hooked by paravirt_ops if needed, and it looks like we
don't want to call paravirt_ops set_pte() here.
I don't know if I understood fully the semantics of set_pte(), but
it seems that the paravirt_ops implementations expect set_pte() to be
called for PTEs that are actually inside existing pagetables (and not
for short-lived stack variables, like on this case).
Was this tested under Xen and/or VMI?

No, you're right. That looks pretty stupid. It will work, but it's
clearly sub-optimal.

Yes, Xen. It's always OK to use set_pte on something that isn't
actually part of a pagetable, since it can be used on pagetables which
are under construction. But it may end up doing too much work.

[-- Attachment #1: x86-normalize-pgtable-formatting.patch --]
[-- Type: text/plain, Size: 11500 bytes --]
Fix up various pieces of unconventional formatting in
asm-x86/pgtable*.h. In some cases, the old formatting was arguablly
clearer with a wide enough terminal, but this patch gives the option
of using a more standard form.

[-- Type: text/plain, Size: 28848 bytes --]
Make pte_t have the same basic structure for all pagetable formats so
that it can be accessed in a uniform way.
This allows a number of follow-on opportunities for sharing code.

i've done a dozen random tests too and it's looking good so far. Nice
work!
pgtable_32.h and pgtable_64.h still look a tiny bit messy from the
include file dependencies POV. For example pgtable_32.h:
#include <asm/processor.h>
#include <asm/fixmap.h>
#include <linux/threads.h>
#include <asm/paravirt.h>
#include <linux/bitops.h>
#include <linux/slab.h>
#include <linux/list.h>
#include <linux/spinlock.h>
that asm/paravirt.h include is already present in pgtable.h, in a
somewhat quirky way:
#ifdef CONFIG_PARAVIRT
#include <asm/paravirt.h>
#else /* !CONFIG_PARAVIRT */
also, most of the:
scripts/checkpatch.pl --file include/asm-x86/pgtable*.h
complaints are real ones and should be fixed.
would you be interested in cleaning up that stuff once and forever? It
would be a fine approach if you just tried to quickly push for a "high
quality" end result in a series of patches and sent that series to me,
without having tested it fully through - i can figure out whatever build
breakages and dependencies there still are. So there would be no
expectation of getting such a cleanup series right in the first (or
second, or third) attempt, this is spaghetti code that has been
accumulated up for years. The important thing would be to be careful to
not introduce runtime breakages accidentally - build breakages due to
some include file dependency we can sort out just fine. Hm?

found a couple of bugs.
firstly, 64-bit wasnt so lucky, you broke iounmap()/change_page_attr()
:-)

secondly, as i tried to bisect it, it would build and boot at this
patch:
Subject: x86: clean up asm-x86/page*.h
but wouldnt build at this patch:
Subject: x86: unify pgtable*.h
nor at this patch:
Subject: x86: fix up formatting in pgtable*.h
it finally built at:
Subject: x86: use a uniform structure for pte_t
but crashed. So the bug is in one of those 3 patches. Please make them
bisect-friendly.
full bootlog and config attached. (The crash happens reliably here - if
you cannot reproduce it then i can try any fix from you. I've removed
the 5 patches of yours for now from x86.git.)

OK. Will beat on this some more. Unfortunately I can only test 64-bit
stuff under kvm, and I'm a little bit skeptical of how solid it is,
since i get sporadic random oopses even with base x86.git. But a nice
simple repeatable BUG_ON should be easy to fix regardless.

well, there's an easy solution for unification patches: the resulting
object files must have _exactly the same_ content as without the
unification patches. (Modulo strings as WARN_ON()s referring to
include-file names.)
If they differ then the unification did something wrong. With your
patchset and the config i sent, the difference is visible in the image
size already:
text data bss dec hex filename
7763766 967330 5812328 14543424 ddea40 vmlinux.after
7763811 967330 5812328 14543469 ddea6d vmlinux.before
also, reducing the size and scope of changes helps as well - because
that way it can be bisected down to specific changes. Mistakes
inevitably happen, especially if you do not enforce a rigid
byte-for-byte correctness along the way. You did 5 rather large patches,
and it's not testable because your unification steps were too coarse.
In other words: you were asking for trouble and you got it :-)

But byte-for-byte identity isn't (necessarily) possible when actually
unifying. If the same function exists in different forms on 32- and
64-bit, then unifying requires I pick one of them (or perhaps a new
superset) to use in the unified form. That function may generate
different code compared to the one that it replaced...
But you're right, I can do the patches in a more piecemeal form. I'll
see if I can rework them.

it's still possible: you can do preparatory patches that bring one
architecture in sync with the other one, in small, per function steps.
Then the actual unification is still an identity transformation. (and
all the preparatory patches are small and bisectable)
it's also a lot less frustrating and a lot more enjoyable that way IMO.
If it's 50 small patches, then so be it ... 50 patches only take ~2
seconds more for me to apply to x86.git (which time is immediately saved
by the vastly improved reviewability and testability of a 50 patches
set), so dont worry about any overhead on the maintainers side. And
you'll end up moving up on the v2.6.25 contributors top-list on LWN as
well ;-) The worst aspect of it is writing up the 50 changelogs (i use
pre-created templates for that) and figuring out how to script a
patch-bomb to lkml. In every other aspect it's a win-win scenario for
everyone involved.

Well, testing for bisectability requires compiling each patch as its
applied, which gets painful for something like this where any change
will rebuild the world. And dealing with patch conflicts caused by
changing early patches in the series is never fun.
But I'm refactoring the series into smaller pieces now. Knowing what
the outcome should look like, and there the pitfalls are, makes it
fairly easy.

that's true. The 'rej' tool helps alot though. ( Plus a distcc cluster
that builds a distro kernel in 45-50 seconds from scratch ;)
