8484baaa50 kernel-doc: code reorganization
Move 'main' code vs. subroutines around so that they are not so
intermixed, for better readability/understanding (relative to Perl).
It was messy to follow the primary flow of code execution with the
code being mixed.  Now the code begins with data initialization,
followed by all subroutines, then ends with the main code execution.

This is almost totally source code movement, with a few changes as
needed for forward declarations.

7ad1227818 kconfig: fix undesirable side effect of adding "visible" menu attribute
This lead to non-selected, non-user-selectable options to be written
out to .config. This is not only pointless, but also preventing the
user to be prompted should any of those options eventually become
visible (e.g. by de-selecting the *_AUTO options the "visible"
attribute was added for.

Furthermore it is quite logical for the "visible" attribute of a menu
to control the visibility of all contained prompts, which is what the
patch does.

731ece41fb modpost: Fix address calculation in reloc_location()
This patch fixes a segfault in modpost that is observed when the gold
linker is used to link the input objects.

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.

aab94339cd of: Add support for linking device tree blobs into vmlinux
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

1137c56b74 kconfig: simplify select-with-unmet-direct-dependency warning
This is an attempt to simplify the expressing printed by kconfig when a
symbol is selected but still has direct unmet dependency.

First, the symbol reverse dependency is split in sub-expression. Then,
each sub-expression is checked to ensure that it does not contains the
unmet dependency. This removes the false-positive symbols and fixed symbol
which already have the correct dependency. Finally, only the symbol
responsible of the "select" is printed, instead of its full dependency tree.

Usefull if building for sparc64 userland, because the

making it impossible to always select the correct userland

Might also be usefull, if you want a i386 userland with a amd64 kernel.

Example usage:
	make KBUILD_DEBARCH=i386 deb-pkg

de323f22a8 headers_check: better search for functions in headers
Some headers don't bother with "extern" in function prototypes, which
results in said prototypes being unnoticed and exported to userland.

This patch slightly improves detection of such cases by checking for C
type names as well in the beginning of a line.

2979076fbf headers_install: check exit status of unifdef
If unifdef fails for any reason (like segfaulting), we should be aborting
the install steps.  So check its exit status in this unlikely scenario.

a1087ef6ab scripts/coccinelle: update for compatability with Coccinelle 0.2.4
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.

e63233f75a ftrace: Have recordmcount honor endianness in fn_ELF_R_INFO
It looks to me like the change which introduced "virtual functions"
forgot about cross-platform endianness.

Thank you to Arnaud for supplying before+after data files do_mounts*.o.

This fixes a MIPS build failure triggered by recordmcount.

0a18a9386c tags: put function prototypes back!
Commit 7db86dc (ctags: usability fix) removed function prototypes from
tags file claiming "It makes no real sense to include function
prototypes".
But it is useful for quickly determining which header file developer
needs to include to fix compilation.

Now if someone wants to remove forward declarations (which I agree are
baggage), write a postprocessing script.
