* kbuild: whitelist references from variables named _timer to .init.textSam Ravnborg2007-07-16
| | | | | | | | | arm uses a lot of ops structures named *_timer that has legitimite references to .init.text. So let's add this variable to the list of variables that may reference .init.text without causing any warning. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kbuild: remove hardcoded _logo names from modpostSam Ravnborg2007-07-16
| | | | | | | | | | Replaced this with a __init_refok marker in front of fb_find_logo(). I think that the __initdata marker for the logo's are wrong but I have not justified this so I did not remove it. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

* kbuild: fix sh64 section mismatch problemsSam Ravnborg2007-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. The following warnings are fixed: WARNING: init/built-in.o(.cranges+0x0): Section mismatch: reference to .init.text: WARNING: init/built-in.o(.cranges+0xa): Section mismatch: reference to .init.text: WARNING: init/built-in.o(.cranges+0x14): Section mismatch: reference to .init.text: WARNING: init/built-in.o(.cranges+0x1e): Section mismatch: reference to .init.text: WARNING: init/built-in.o(.cranges+0x28): Section mismatch: reference to .init.text: WARNING: init/built-in.o(.cranges+0x32): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x50): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x5a): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x64): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0xfa): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x104): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x10e): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x14a): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x154): Section mismatch: reference to .init.text: WARNING: kernel/built-in.o(.cranges+0x15e): Section mismatch: reference to .init.text: WARNING: mm/built-in.o(.cranges+0x6e): Section mismatch: reference to .init.text: WARNING: mm/built-in.o(.cranges+0x78): Section mismatch: reference to .init.text: WARNING: mm/built-in.o(.cranges+0x82): Section mismatch: reference to .init.text: WARNING: mm/built-in.o(.cranges+0xaa): Section mismatch: reference to .init.text: WARNING: fs/built-in.o(.cranges+0x136): Section mismatch: reference to .init.text: WARNING: fs/built-in.o(.cranges+0x140): Section mismatch: reference to .init.text: WARNING: fs/built-in.o(.cranges+0x14a): Section mismatch: reference to .init.text: WARNING: fs/built-in.o(.cranges+0x168): Section mismatch: reference to .init.text: WARNING: fs/built-in.o(.cranges+0x1f4): Section mismatch: reference to .init.text: WARNING: fs/built-in.o(.cranges+0x1fe): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x302): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x30c): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x316): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x3a2): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x3ac): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x4ce): Section mismatch: reference to .init.text: WARNING: net/built-in.o(.cranges+0x4d8): Section mismatch: reference to .init.text: Signed-off-by: Paul Mundt <lethal@linux-sh.org> Cc: Kaz Kojima <kkojima@rr.iij4u.or.jp> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

| | | | | | | | | | | | | | | | | warnings Throughout the kernel there are a few legitimite references to init or exit sections. Most of these are covered by the patterns included in modpost but a few nees special attention.

When modpost see a reference to a init/exit function from a function/data marked no warning will be issued.

* powerpc: Fix the MODALIAS generation in modpost for of devicesSylvain Munaut2007-05-19
| | | | | | | | | | | | | | | | Since the devices may have multiple (or none) compatible properties, the uevent generated internally by the kernel may have multiple "C..." entries. So the MODALIAS stored in the module must have wilcard before and after the compatible entry. Also, if the 'compatible' field is not used for matching, there will be no 'C' and that must handled as well. The previous code handled all those case incorrectly and it "mostly" worked ... but not always.

* Add white list into modpost.c for memory hotplug code and ia64's machvec sectionYasunori Goto2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* blackfin architectureBryan Wu2007-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | | [PATCH] remove modpost false warnings on ARMDavid Brownell2007-02-20

A canonical example would be driver method table entries: WARNING: <path> - Section mismatch: reference to .exit.text:<name>_remove from .data after '$d' (at offset 0x4) That "$d" symbol is generated by tools conformant with ARM ABI specs; in this case it's a symbol **in the middle of** a "<name>_driver" struct. The erroneous warnings appear to be issued because "modpost" whitelists references from "<name>_driver" data into init and exit sections ... but doesn't know should also include those "$d" mapping symbols, which are not otherwise associated with "<name>_driver" symbols. This patch prevents the modpost symbol lookup code from ever returning those mapping symbols, so it will return a whitelisted symbol instead. Then things work as expected. Now to revert various code-bloating "fixes" that got merged because of this modpost bug....

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that the most called ops, by several orders of magnitude, are the interrupt manipulation ops. These are obvious candidates for patching, so mark them up and create infrastructure for it. The method used is that the ops structure has a patch function, which is called for each place which needs to be patched: this returns a number of instructions (the rest are NOP-padded). Usually we can spare a register (%eax) for the binary patched code to use, but in a couple of critical places in entry.S we can't: we make the clobbers explicit at the call site, and manually clobber the allowed registers in debug mode as an extra check.

* [PATCH] EISA bus MODALIAS attributes supportMichael Tokarev2006-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add modalias attribute support for the almost forgotten now EISA bus and (at least some) EISA-aware modules. The modalias entry looks like (for an 3c509 NIC): eisa:sTCM5093 and the in-module alias like: eisa:sTCM5093* The patch moves struct eisa_device_id declaration from include/linux/eisa.h to include/linux/mod_devicetable.h (so that the former now #includes the latter), adds proper MODULE_DEVICE_TABLE(eisa, ...) statements for all drivers with EISA IDs I found (some drivers already have that DEVICE_TABLE declared), and adds recognision of __mod_eisa_device_table to scripts/mod/file2alias.c so that proper modules.alias will be generated. There's no support for /lib/modules/$kver/modules.eisamap, as it's not used by any existing tools, and because with in-kernel modalias mechanism those maps are obsolete anyway. The rationale for this patch is: a) to make EISA bus to act as other busses with modalias support, to unify driver loading b) to foget about EISA finally - with this patch, kernel (who still supports EISA) will be the only one who knows how to choose the necessary drivers for this bus ;) [akpm@osdl.org: fix the kbuild bit] Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Randy Dunlap <rdunlap@xenotime.net> Acked-the-net-bits-by: Jeff Garzik <jeff@garzik.org> Acked-the-tulip-bit-by: Valerie Henson <val_henson@linux.intel.com> Cc: James Bottomley <James.Bottomley@steeleye.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* kbuild: fail kernel compilation in case of unresolved module symbolsKirill Korotaev2006-09-25
| | | | | | | | | | | | | | | | | | | At stage 2 modpost utility is used to check modules. In case of unresolved symbols modpost only prints warning. IMHO it is a good idea to fail compilation process in case of unresolved symbols (at least in modules coming with kernel), since usually such errors are left unnoticed, but kernel modules are broken. - new option '-w' is added to modpost: if option is specified, modpost only warns about unresolved symbols - modpost is called with '-w' for external modules in Makefile.modpost Signed-off-by: Andrey Mirkin <amirkin@sw.ru> Signed-off-by: Kirill Korotaev <dev@openvz.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
