* i2c: Kill struct i2c_device_idJean Delvare2007-10-131-11/+0
| | | | | | | | | | I2C devices do not have any form of ID as PCI or USB devices have. No driver uses "MODULE_DEVICE_TABLE(i2c, ...)" because it doesn't make sense. So we can get rid of struct i2c_device_id and the associated support code. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Greg KH <greg@kroah.com>

| * [NETNS]: Move some code into __init section when CONFIG_NET_NS=nPavel Emelyanov2007-10-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the net namespaces many code leaved the __init section, thus making the kernel occupy more memory than it did before. Since we have a config option that prohibits the namespace creation, the functions that initialize/finalize some netns stuff are simply not needed and can be freed after the boot. Currently, this is almost not noticeable, since few calls are no longer in __init, but when the namespaces will be merged it will be possible to free more code. I propose to use the __net_init, __net_exit and __net_initdata "attributes" for functions/variables that are not used if the CONFIG_NET_NS is not set to save more space in memory. The exiting functions cannot just reside in the __exit section, as noticed by David, since the init section will have references on it and the compilation will fail due to modpost checks. These references can exist, since the init namespace never dies and the exit callbacks are never called. So I introduce the __exit_refok attribute just like it is already done with the __init_refok.

| * [SSB]: add Sonics Silicon Backplane bus supportMichael Buesch2007-10-101-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | SSB is an SoC bus used in a number of embedded devices. The most well-known of these devices is probably the Linksys WRT54G, but there are others as well. The bus is also used internally on the BCM43xx and BCM44xx devices from Broadcom. This patch also includes support for SSB ID tables in modules, so that SSB drivers can be loaded automatically. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W.

* kbuild: fix modpost warnings for xtensaSam Ravnborg2007-07-251-6/+24
| | | | | | | | | | | | | | | | | | | The Xtensa architecture places literal pools in sections separate from the instructions. The corresponsing text sections, therefore, reference the .literal section, and we have to suppress those warnings. The naming convention defines the name for a literal section as .SECTION.literal, unless .SECTION is .text. In that case the name is only .literal. Using strncmp() instead of strcmp() to compare the from-section with .SECTION.init.refok in pattern 0 should not cause any regressions for other architectures. We also need to suppress warnings for two informational sections (.xt.lit and .xt.prop) used by the Xtensa architecture.

* kbuild: do section mismatch check on full vmlinuxSam Ravnborg2007-07-171-1/+2
| | | | | | | | | | | | | | | Previously we did do the check on the .o files used to link vmlinux but that failed to find questionable references across the .o files. Create a dedicated vmlinux.o file used only for section mismatch checks that uses the defualt linker script so section does not get renamed. The vmlinux.o may later be used as part of the the final link of vmlinux but for now it is used fo section mismatch only.

* kbuild: fix sh64 section mismatch problemsSam Ravnborg2007-06-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a special .cranges section that is almost always generated, with data being moved to the appropriate section by the linker at a later stage. To give a bit of background, sh64 has both a native SHmedia instruction set (32-bit instructions) and SHcompact (which is compatability with normal SH -- 16-bit, a massively reduced register set, etc.). code ranges are emitted when we're using the 32-bit ABI, but not the 64-bit one. It is a special staging section used solely by binutils where code with different flags get placed (more specifically differing flags for input and output sections), before being lazily merged by the linker. The closest I've been able to find to documentation is: http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/ld/emultempl/sh64elf.em?rev=1.10&content-type=text/x-cvsweb-markup&cvsroot=src It's an array of 8-byte Elf32_CRange structure given in http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/bfd/elf32-sh64.h?rev=1.4&content-type=text/x-cvsweb-markup&cvsroot=src that describes for which ISA a range is used. Silence the warnings by allowing references from .init.text to .cranges.

* Add white list into modpost.c for memory hotplug code and ia64's machvec sectionYasunori Goto2007-05-081-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | This patch is add white list into modpost.c for some functions and ia64's section to fix section mismatchs. sparse_index_alloc() and zone_wait_table_init() calls bootmem allocator at boot time, and kmalloc/vmalloc at hotplug time. If config memory hotplug is on, there are references of bootmem allocater(init text) from them (normal text). This is cause of section mismatch. Bootmem is called by many functions and it must be used only at boot time. I think __init of them should keep for section mismatch check. So, I would like to register sparse_index_alloc() and zone_wait_table_init() into white list. In addition, ia64's .machvec section is function table of some platform dependent code. It is mixture of .init.text and normal text. These reference of __init functions are valid too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the Analog Devices Blackfin processor architecture, and currently supports the BF533, BF532, BF531, BF537, BF536, BF534, and BF561 (Dual Core) devices, with a variety of development platforms including those avaliable from Analog Devices (BF533-EZKit, BF533-STAMP, BF537-STAMP, BF561-EZKIT), and Bluetechnix! Tinyboards. The Blackfin architecture was jointly developed by Intel and Analog Devices Inc. (ADI) as the Micro Signal Architecture (MSA) core and introduced it in December of 2000. Since then ADI has put this core into its Blackfin processor family of devices. The Blackfin core has the advantages of a clean, orthogonal,RISC-like microprocessor instruction set. It combines a dual-MAC (Multiply/Accumulate), state-of-the-art signal processing engine and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture. The Blackfin architecture, including the instruction set, is described by the ADSP-BF53x/BF56x Blackfin Processor Programming Reference http://blackfin.uclinux.org/gf/download/frsrelease/29/2549/Blackfin_PRM.pdf The Blackfin processor is already supported by major releases of gcc, and there are binary and source rpms/tarballs for many architectures at: http://blackfin.uclinux.org/gf/project/toolchain/frs There is complete documentation, including "getting started" guides available at: http://docs.blackfin.uclinux.org/ which provides links to the sources and patches you will need in order to set up a cross-compiling environment for bfin-linux-uclibc This patch, as well as the other patches (toolchain, distribution, uClibc) are actively supported by Analog Devices Inc, at: http://blackfin.uclinux.org/ We have tested this on LTP, and our test plan (including pass/fails) can be found at: http://docs.blackfin.uclinux.org/doku.php?id=testing_the_linux_kernel [m.kozlowski@tuxland.pl: balance parenthesis in blackfin header files] Signed-off-by: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Mariusz Kozlowski <m.kozlowski@tuxland.pl> Signed-off-by: Aubrey Li <aubrey.li@analog.com> Signed-off-by: Jie Zhang <jie.zhang@analog.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * kbuild: do not emit src version warning for non-modulesSam Ravnborg2007-05-021-3/+2
| | | | | | | | | | | | | | | | modpost is now called with .o files that are not modules. So do not warn if there is no corresponding .mod file listing .o files (in .tmp_versions/). Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
| * kbuild: distinguish between errors and warnings in modpostMatthew Wilcox2007-05-022-3/+20
| | | | | | | | | | | | | | | | | | | | Some of modpost's warnings are fatal, and some are not. Adopt the compiler distinction between errors and warnings by calling merror() for fatal diagnostics and warn() for non-fatal ones. merror() was used as replacemtn for error() to avoid clash with glibc Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

| * kbuild: whitelist logo references from .text to .init.dataSam Ravnborg2007-05-021-0/+15
| | | | | | | | | | | | | | | | | | drivers/video/logo has references from .text to .init.data but function is only used during early init. So reference is OK and we do not want to warn about them => whitelist the reference. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
| * kbuild: fix segmentation fault in modpostSam Ravnborg2007-05-021-2/+6
| | | | | | | | | | | | | | If modpost was called manually with filenames without '/' then modpost would segfault. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
| * kbuild: fix warnings from .pci_fixup sectionSam Ravnborg2007-05-021-19/+25
| | | | | | | | | | | | | | | | | | Now where we do not pass vmlinux to modpost we started to see section mismatch warnings from .pci_fixup. Refactored code a little to include these in the whitelist again. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
| * kbuild: whitelist section mismatch in init/main.cSam Ravnborg2007-05-021-1/+14
| | | | | | | | | | | | | | | | | | In init/main.c we have a reference from rest_init() to .init.text which is intentional. Rename the function 'init' to 'kernel_init' to make it a kernel wide unique symbol and whitelist the reference. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
| * kbuild: fix section mismatch check for vmlinuxSam Ravnborg2007-05-021-12/+21
| | | | | | | | | | | | | | | | | | | | | | | | vmlinux does not contain relocation entries which is used by the section mismatch checks. Reported by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Use the individual objects as inputs to overcome this limitation. In modpost check the .o files and skip non-ELF files.
