2007-07-31kbuild: whitelist references from __dbe_table to .initRalf Baechle

2007-07-25kbuild: fix modpost warnings for xtensaSam Ravnborg
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.

2007-07-25kbuild: be more foregiving on init section namingSam Ravnborg
In the whitelist function of modpost now use the same check to identify init_section as in other places of modpost. This has the effect that we now recognize sections named .init.text.19 as init sections and we no longer warn when we see these. At the same time make surrounding code readable by dropping use of temporary flags. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2007-07-17kbuild: do section mismatch check on full vmlinuxSam Ravnborg
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. For a defconfig build this is instant but for an allyesconfig this add two minutes to a full build (that anyways takes ~2 hours). Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2007-06-11kbuild: fix sh64 section mismatch problemsSam Ravnborg
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>

2007-05-08Add white list into modpost.c for memory hotplug code and ia64's machvec sectionYasunori Goto
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.

2007-05-07blackfin architectureBryan Wu
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>

o Modpost generates warnings for i386 if compiled with CONFIG_RELOCATABLE=y WARNING: vmlinux - Section mismatch: reference to .init.text:find_unisys_acpi_oem_table from .text between 'acpi_madt_oem_check' (at offset 0xc0101eda) and 'enable_apic_mode' WARNING: vmlinux - Section mismatch: reference to .init.text:acpi_get_table_header_early from .text between 'acpi_madt_oem_check' (at offset 0xc0101ef0) and 'enable_apic_mode' WARNING: vmlinux - Section mismatch: reference to .init.text:parse_unisys_oem from .text between 'acpi_madt_oem_check' (at offset 0xc0101f2e) and 'enable_apic_mode' WARNING: vmlinux - Section mismatch: reference to .init.text:setup_unisys from .text between 'acpi_madt_oem_check' (at offset 0xc0101f37) and 'enable_apic_mode'WARNING: vmlinux - Section mismatch: reference to .init.text:parse_unisys_oem from .text between 'mps_oem_check' (at offset 0xc0101ec7) and 'acpi_madt_oem_check' WARNING: vmlinux - Section mismatch: reference to .init.text:es7000_sw_apic from .text between 'enable_apic_mode' (at offset 0xc0101f48) and 'check_apicid_present' o Some functions which are inline (acpi_madt_oem_check) are not inlined by compiler as these functions are accessed using function pointer. These functions are put in .text section and they in-turn access __init type functions hence modpost generates warnings. o Do not iniline acpi_madt_oem_check, instead make it __init.

2007-02-20[PATCH] remove modpost false warnings on ARMDavid Brownell
This patch stops "modpost" from issuing erroneous modpost warnings on ARM builds, which it's been doing since since maybe last summer. 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....
