scripts/mod/modpost.c: permit '.cranges' secton for sh64 architecture.

2013-08-20T06:07:40Z

Need permit '.cranges' section for sh64 architecture, or modpost will report warning: LD init/built-in.o WARNING: init/built-in.o (.cranges): unexpected non-allocatable section. Did you forget to use "ax"/"aw" in a .S file? Note that for example contains section definitions for use in .S files. Signed-off-by: Chen Gang Signed-off-by: Rusty Russell

Merge branch 'cpuinit-delete' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux

2013-07-07T18:01:19Z

Pull first stage of __cpuinit removal from Paul Gortmaker: "The two commits here 1) dummy out all the __cpuinit macros so that we no longer generate such sections, and then 2) remove all the section processing that we used to do for those sections. This makes all the __cpuinit and friends no-ops, so that we can remove the use cases of it at our leisure. Expect stage 2, which does the tree wide removal sweep at the end of the merge window." * 'cpuinit-delete' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: modpost: remove all traces of cpuinit/cpuexit sections init.h: remove __cpuinit sections from the kernel

modpost: remove all traces of cpuinit/cpuexit sections

2013-06-26T16:17:06Z

Delete all audit rules that were checking how the .cpuXYZ related sections were inter-operating with other __init like sections, now that __cpuinit is gone. Update the linker script to not have any knowledge of .cpuinit sections. [lds.h update courtesy of Ralf Baechle ] Cc: Arnd Bergmann Cc: Rusty Russell Signed-off-by: Paul Gortmaker

modpost.c: Add .text.unlikely to TEXT_SECTIONS

2013-05-20T02:38:45Z

gcc's places cold functions into the .text.unlikely section and we need to check this section as well for section mismatches otherwise we may have false negatives for this test.

modpost: fix unwanted VMLINUX_SYMBOL_STR expansion

2013-04-29T02:11:42Z

Commit a4b6a77b77ba4f526392612c2365797fab956014 ("module: fix symbol versioning with symbol prefixes") broke the MODVERSIONS loading of any module using memcmp (e.g. ipv6) on x86_32, as it's defined to __builtin_memcmp which is expanded by VMLINUX_SYMBOL_STR. Use __VMLINUX_SYMBOL_STR instead which doesn't expand the argument. Reported-by: Tetsuo Handa Reported-by: Andy Shevchenko Signed-off-by: James Hogan Cc: H.

modpost: add -T option to read module names from file/stdin.

Because there are too many modules in the world. Signed-off-by: Rusty Russell

modpost: minor cleanup.

We want a strends() function next, so make one and use it appropriately, making new_module() arg const while we're at it. Signed-off-by: Rusty Russell

module: fix symbol versioning with symbol prefixes

2013-03-20T00:57:26Z

Fix symbol versioning on architectures with symbol prefixes. Although the build was free from warnings the actual modules still wouldn't load as the ____versions table contained unprefixed symbol names, which were being compared against the prefixed symbol names when checking the symbol versions. This is fixed by modifying modpost to add the symbol prefix to the ____versions table it outputs (Modules.symvers still contains unprefixed symbol names). The check_modstruct_version() function is also fixed as it checks the version of the unprefixed "module_layout" symbol which would no longer work.

CONFIG_SYMBOL_PREFIX: cleanup.

2013-03-15T04:39:43Z

We have CONFIG_SYMBOL_PREFIX, which three archs define to the string "_". But Al Viro broke this in "consolidate cond_syscall and SYSCALL_ALIAS declarations" (in linux-next), and he's not the first to do so. Using CONFIG_SYMBOL_PREFIX is awkward, since we usually just want to prefix it so something. So various places define helpers which are defined to nothing if CONFIG_SYMBOL_PREFIX isn't set: 1) include/asm-generic/unistd.h defines __SYMBOL_PREFIX. 2) include/asm-generic/vmlinux.lds.h defines VMLINUX_SYMBOL(sym) 3) include/linux/export.h defines MODULE_SYMBOL_PREFIX. 4) include/linux/kernel.h defines SYMBOL_PREFIX (which differs from #7) 5) kernel/modsign_certificate.S defines ASM_SYMBOL(sym) 6) scripts/modpost.c defines MODULE_SYMBOL_PREFIX 7) scripts/Makefile.lib defines SYMBOL_PREFIX on the commandline if CONFIG_SYMBOL_PREFIX is set, so that we have a non-string version for pasting. (arch/h8300/include/asm/linkage.h defines SYMBOL_NAME(), too). Let's solve this properly: 1) No more generic prefix, just CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX. 2) Make linux/export.h usable from asm. 3) Define VMLINUX_SYMBOL() and VMLINUX_SYMBOL_STR(). 4) Make everyone use them.

Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild

2013-02-27T20:25:47Z

Pull kbuild changes from Michal Marek: - Alias generation in modpost is cross-compile safe. - kernel/timeconst.h is now generated using a bc script instead of perl. - scripts/link-vmlinux.sh now works with an alternative $KCONFIG_CONFIG. - destination-y for exported headers is supported in Kbuild files again. - depmod is called with -P $CONFIG_SYMBOL_PREFIX on architectures that need it. - CONFIG_DEBUG_INFO_REDUCED disables var-tracking - scripts/setlocalversion works with too much translated locales ;) * 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: kbuild: Fix reading of .config in link-vmlinux.sh kbuild: Unset language specific variables in setlocalversion script Kbuild: Disable var tracking with CONFIG_DEBUG_INFO_REDUCED depmod: pass -P $CONFIG_SYMBOL_PREFIX kbuild: Fix destination-y for installed headers scripts/link-vmlinux.sh: source variables from KCONFIG_CONFIG kernel: Replace timeconst.pl with a bc script mod/file2alias: make modalias generation safe for cross compiling
