* scripts/get_maintainer.pl: use --git-fallback more oftenJoe Perches2011-01-131-1/+37

The MAINTAINERS entry for mm is: MEMORY MANAGEMENT L: linux-mm@kvack.org W: http://www.linux-mm.org S: Maintained F: include/linux/mm.h F: mm/ There's a maintainer entry, but no named individual, so the script doesn't use git history via --git-fallback. This is also a defect for MAINTAINERS with status entries marked "Orphan" or "Odd fixes". The script now checks a section for any "M:" entry and that an "S:" entry is supported or maintained. If both those conditions are not satisified, use --git-fallback as appropriate.

* scripts/get_maintainer.pl: make --rolestats the defaultJoe Perches2011-01-131-3/+4
| | | | | | | | | | | | | | This script now requires a user to add --norolestats to the command line so it's harder to feed the output of this script to programs that send mass emails. Update --help to correct command line defaults. Change version to 0.26.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Pull in recent changes from the main dtc repository. These changes primarily allow multiple device trees to be declared which are merged by dtc. This feature allows us to include a basic dts file and then provide more information for the specific system through the merging functionality.

| * of: Add support for linking device tree blobs into vmlinuxDirk Brandewie2010-12-231-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for linking device tree blob(s) into vmlinux. Modifies asm-generic/vmlinux.lds.h to add linking .dtb sections into vmlinux. To maintain compatiblity with the of/fdt driver code platforms MUST copy the blob to a non-init memory location before the kernel frees the .init.* sections in the image. Modifies scripts/Makefile.lib to add a kbuild command to compile DTS files to device tree blobs and a rule to create objects to wrap the blobs for linking. STRUCT_ALIGNMENT is defined in vmlinux.lds.h for use in the rule to create wrapper objects for the dtb in Makefile.lib. The STRUCT_ALIGN() macro in vmlinux.lds.h is modified to use the STRUCT_ALIGNMENT definition. The DTB's are placed on 32 byte boundries to allow parsing the blob with driver/of/fdt.c during early boot without having to copy the blob to get the structure alignment GCC expects. A DTB is linked in by adding the DTB object to the list of objects to be linked into vmlinux in the archtecture specific Makefile using obj-y += foo.dtb.o Signed-off-by: Dirk Brandewie <dirk.brandewie@gmail.com> Acked-by: Michal Marek <mmarek@suse.cz> [grant.likely@secretlab.ca: cleaned up whitespace inconsistencies] Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For doubleinit.cocci, Coccinelle 0.2.4 requires a comma after ... in a field list. Coccinelle also now behaves gracefully when a definition is provided for a virtual that doesn't exist, so there is no need for the semantic patch code to check for this case. Updated the documentation to reflect the fact that the best results will now be obtained with Coccinelle version 0.2.4 or later. Signed-off-by: Julia Lawall <julia@diku.dk>

But it is useful for quickly determining which header file developer needs to include to fix compilation.

If it can't find a proper Debian userspace it displays a warning, and fallback to let deb-gencontrol use the host's userspace arch. Eg. with this patch the following make command: make ARCH=i386 deb-pkg will output an i386 Debian package instead of an amd64 one, when run on an amd64 machine.

The problem is that reloc_location (modpost.c) is computing the address of the relocation target incorrectly. Here, elf->hdr points to the beginning of the ELF file in memory, sechdr points to the relocation section header, section is the index of the section being relocated, and sechdrs[section].sh_offset would be the offset of that section, relative to the beginning of the ELF file. Adding elf->hdr + sechdrs[section].sh_offset gives you the address of the beginning of the section, and adding r->r_offset to that gives you the address of the location to be relocated. You do not need to subtract sechdrs[section].sh_addr from that -- the result of this is an address outside the file, and causes the segfault when addend_386_rel tries to dereference it. This bug is not observed when GNU ld is used to link the inputs. The object file ubuntu/omnibook/omnibook.o is the result of an ld -r of several other files. When GNU ld does an ld -r, it sets the vaddr field for each section to 0, but gold lays out the section addresses sequentially instead: Section Headers: [Nr] Name Type Addr Off Size ES Flg Lk Inf Al [ 0] NULL 00000000 000000 000000 00 0 0 0 [ 1] .text PROGBITS 00000000 000034 004794 00 AX 0 0 4 [ 2] .data PROGBITS 0000b9d0 0047c8 0009c0 00 WA 0 0 4 [ 3] .bss NOBITS 000162f8 005188 00013c 00 WA 0 0 4 [ 4] .rodata.str1.1 PROGBITS 00004f2d 0052c4 001b1a 01 AMS 0 0 1 [ 5] .init.text PROGBITS 00004794 006dde 0005fa 00 AX 0 0 1 [ 6] .exit.text PROGBITS 00004d8e 0073d8 00018a 00 AX 0 0 1 ... So the bug in the tool remained undiscovered because the section's vaddr always happened to be 0.
