arch/powerpc/platforms/44x/warp-nand.c was added this year and updated quite recently. warp-nand.c is empty unless CONFIG_MTD_NAND_NDFC=y. MTD_NAND_NDFC depends on !PPC_MERGE. !PPC_MERGE can never be true on PPC now that arch/ppc/ got removed.

[2.6 patch] sata_fsl.c: fix 8315DS workaround

MPC8315DS link speed limit workaround to specific ifdef) aimed at
limiting the workaround only to the affected hardware, but since the
#ifdef used a nonexisting kconfig variable it actually killed

You already marked it as "Obsolete" more than 2 years ago, and due the kconfig dependencies most people anyway won't even see the option (since they have HVC_ISERIES enabled).

A grep through the tree and one test compile that covers sound/soc/soc-dapm.c should be enough testing. And having it then in -next once should be enough to discover if someone wrongly added a new user. I have removed many functions in the kernel, and there isn't much that can go wrong - even adding a PCI ID to a driver has a bigger risk of introducing a regression. > thanks, > > Takashi cu Adrian -- "Is there not promise of rain?"

My point is simply that compared to many other patches that weren't tested before the merge window, and that still get (for various reasons) into the tree, the removal of unused functions is extremely low-risk (assuming the patch creator knows what grep is and does a test compile of the changed code). > thanks, > > Takashi cu Adrian -- "Is there not promise of rain?"

This means it generates faster code with a current gcc for your platform.
But a future gcc might e.g. replace the whole loop with a division
(gcc SVN head (that will soon become gcc 4.3) already does
transformations like replacing loops with divisions [1]).
And your __builtin_expect() then might have unwanted effects on gcc.
Or the kernel code changes much but the likely/unlikely stays unchanged
although it becomes wrong.
If it is a real hotpath in the kernel where you have _measurable_
performance advantages from using likely/unlikely it's usage might be
justified, but otherwise it shouldn't be used.
> cheers

Adrian
[1] e.g. the while() loop in timespec_add_ns() in include/linux/time.h
gets replaced by a division and a modulo (whether this
transformation is correct in this specific case is a different
question, but that's the level of code transformation gcc already
does today)

That's a different issue. My point here is that we do not know how the latest gcc available in the year 2010 might transform this code, and how a likely/unlikely placed there might influence gcc's optimizations then. If this is in hotpath code with a measurable speedup when using likely/unlikely with a current gcc then it's worth it. But otherwise it brings no real advantage today and the longterm effects are not predictable. > With kind regards, > > Geert Uytterhoeven cu Adrian -- "Is there not promise of rain?"

After all the unlikely/likely is just a hint, if gcc > knows better it can always ignore it. It's the other way round, gcc assumes that you know better than gcc when you give it a __builtin_expect(). The example you gave had only a 1:3 ratio, which is far outside of the ratios where __builtin_expect() should be used. What if you gave this annotation for the 1:3 case and gcc generates code that performs better for ratios > 1:1000 but much worse for a 1:3 ratio since your hint did override a better estimate of gcc?

I'm a firm believer in the following: - it's the programmer's job to write clean and efficient C code - it's the compiler's job to convert C code into efficient assembler code The stable interface between the programmer and the compiler is C, and when the programmer starts manually messing with internals of the compiler that's a layering violation that requires a _good_ justification. With a "good justification" not consisting of some microbenchmark but of measurements of the actual annotations in the kernel code. > cheers cu Adrian -- "Is there not promise of rain?"

I start to understand the problem, and I'm currently wondering why powerpc uses CONFIG_NVRAM although the code CONFIG_NVRAM enables on other platforms is not enabled on powerpc.

Thanks for your report. I assume this is reproducible? If yes, what was the last kernel that worked for you?

Please don't do this kind of patches - it doesn't bring any advantage but can create tons of patch conflicts. The next time a defconfig gets updated it will anyway automatically be fixed, and for defconfigs that aren't updated it doesn't create any problems to keep them as they are today until they might one day get updated. cu Adrian -- "Is there not promise of rain?"

What about my patch [1] to eliminate this new trap in kconfig since we do not have to bother kconfig users with ATA_SFF at all? Besides some orthoginal discussion whether this stuff should actually be called SFF I am not aware of any reactions to my patch from the ATA people. I already sent this patch twice and I can update it to the latest tree if it's considered OK, but I'd like to get some ACK/NAK first. cu Adrian [1] http://lkml.org/lkml/2008/4/21/501 -- "Is there not promise of rain?"

Updated patch below.

<-- snip -->
This patch contains the following possible cleanups:
- make the following needlessly global code static:
- adb.c: adb_controller
- adb.c: adb_init()
- adbhid.c: adb_to_linux_keycodes[] (also make it const)
- via-pmu68k.c: backlight_level
- via-pmu68k.c: backlight_enabled
- remove the following unused code:
- via-pmu68k.c: sleep_notifier_list

[2.6 patch] asm/ptrace.h userspace headers cleanup
This patch contains the following cleanups for the asm/ptrace.h
userspace headers:
- include/asm-generic/Kbuild.asm already lists ptrace.h, remove
the superfluous listings in the Kbuild files of the following
architectures:
- cris
- frv
- powerpc
- x86
- don't expose function prototypes and macros to userspace:
- arm
- blackfin
- cris
- mn10300
- parisc
- remove #ifdef CONFIG_'s around #define's:
- blackfin
- m68knommu
- sh: AFAIK __SH5__ should work in both kernel and userspace,
no need to leak CONFIG_SUPERH64 to userspace
- xtensa: cosmetical change to remove empty
#ifndef __ASSEMBLY__ #else #endif
from the userspace headers
Signed-off-by: Adrian Bunk <[EMAIL PROTECTED]>
---
Not changed by this patch is the fact that the following architectures
have a different struct pt_regs depending on CONFIG_ variables:
- h8300
- m68knommu
- mips
This does not work in userspace.

Honestly, I do not completely like your approach of getting the microblaze port submitter to create the asm-generic files - I would personally prefer if the microblaze port would look exactly like all other ports and the (reasonable) changes you have in mind were not being discussed and done as part of the submission of a new port. After all, it won't matter whether we'll unify resp. remove 22 or 23 files. > Arnd <>< cu Adrian -- "Is there not promise of rain?" Ling Tan asked suddenly out of the darkness.

When microblaze is in, Discussions of the "big picture" should be in an own thread, not as part of a merge of a new architecture. I am not an architecture maintainer, but I do not like the way you want to couple the microblaze merge with the move of stuff to asm-generic. They both make sense, but they are clearly separate issues. > I can compile a list > with asm-generic files that can be used to replace the architecture > specific files, so the arch maintainers can decide on their own > whether to clean their own stuff up or not. >... We need either all architectures changed or none at all - we do need the arch headers to become more similar, not more different. And this is why we need an agreement _before_ an asm-generic header gets added, not after it. > Arnd <>< cu Adrian -- "Is there not promise of rain?" Ling Tan asked suddenly out of the darkness.

But if you move it to any header file gcc is able to figure out such errors itself instead of them being nasty runtime errors. Such prototypes in C files are really bad since (like in this case) they prevent the finding of bugs.

[2.6 patch] powerpc: proper defconfig for crosscompiles
The trick for finding the right defconfig is neat, but you forgot to provide an i686_defconfig. ;-) More seriously, cross compiling the defconfig is often useful, e.g. for testing the compilation of patches that touch multiple architectures, and this patch therefore chooses g5_defconfig if $(CROSS_COMPILE) is non-empty.
