kbuild, modpost: fix unexpected non-allocatable warning with mips

2009-05-04T11:05:26Z

mips emit the following debug sections: .mdebug* and .pdr They were included in the check for non-allocatable section and caused modpost to warn. Manuel Lauss suggested to fix this by adding the relevant sections to the list of sections we do not check. Signed-off-by: Sam Ravnborg Reported-by: Manuel Lauss

kbuild, modpost: fix "unexpected non-allocatable" warning with SUSE gcc

2009-05-04T11:05:06Z

Jean reported that he saw one warning for each module like the one below: WARNING: arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.o (.comment.SUSE.OPTs): unexpected non-allocatable section. The warning appeared with the improved version of the check of the flags in the sections. That check already ignored sections named ".comment" - but SUSE store additional info in the comment section and has named it in a SUSE specific way. Therefore modpost failed to ignore the section. The fix is to extend the pattern so we ignore all sections that start with the name ".comment.". Signed-off-by: Sam Ravnborg Reported-by: Jean Delvare Tested-by: Jean Delvare

kbuild, modpost: fix unexpected non-allocatable section when cross compiling

2009-05-04T11:05:03Z

The missing TO_NATIVE(sechdrs[i].sh_flags) was causing many unexpected non-allocatable section warnings when cross-compiling for an architecture with a different endianness. Fix endianness of all the fields in the ELF header and section headers, not just some of them so we are not hit by this anohter time.

Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtc

2009-05-02T23:52:26Z

The powerpc kernel always requires an Open Firmware like device tree to supply device information. On systems without OF, this comes from a flattened device tree blob. This blob is usually generated by dtc, a tool which compiles a text description of the device tree into the flattened format used by the kernel. Sometimes, the bootwrapper makes small changes to the pre-compiled device tree blob (e.g. filling in the size of RAM). To do this it uses the libfdt library. Because these are only used on powerpc, the code for both these tools is included under arch/powerpc/boot (these were imported and are periodically updated from the upstream dtc tree). However, the microblaze architecture, currently being prepared for merging to mainline also uses dtc to produce device tree blobs. A few other archs have also mentioned some interest in using dtc. Therefore, this patch moves dtc and libfdt from arch/powerpc into scripts, where it can be used by any architecture. The vast bulk of this patch is a literal move, the rest is adjusting the various Makefiles to use dtc and libfdt correctly from their new locations.

kernel-doc: restrict syntax for private: and public:

2009-05-02T22:36:10Z

scripts/kernel-doc can (incorrectly) delete struct members that are surrounded by /* ... */ /* ... */ if there is a /* private: */ comment in there somewhere also. Fix that by making the "/* private:" only allow whitespace between /* and "private:", not anything/everything in the world. This fixes some erroneous kernel-doc warnings that popped up while processing include/linux/usb/composite.h. Signed-off-by: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kbuild, modpost: Check the section flags, to catch missing "ax"/"aw"

2009-05-01T08:54:05Z

When you put .section ".foo" in an assembly file instead of .section "foo", "ax" , one of the possible symptoms is that modpost will see an ld-generated section name ".foo.1" in section_rel() or section_rela(). But this heuristic has two problems: it will miss a bad section that has no relocations, and it will incorrectly flag many gcc-generated sections as bad when compiling with -ffunction-sections -fdata-sections. On mips it fixes a lot of bogus warnings with gcc 4.4.0 lije this one: WARNING: crypto/cryptd.o (.text.T.349): unexpected section name. So instead of checking whether the section name matches a particular pattern, we directly check for a missing SHF_ALLOC in the section flags.

kbuild: fix scripts/setlocalversion with git

2009-05-01T08:54:04Z

When using trees like wireless-testing, which have untagged tags, scripts/setlocalversion does not display any git indication for localversion. This patch fixes it: If git is available, but no usable tag is found, it uses -g${head}. It skips the detection of unanottated tags via git name-rev.
