The sed expression used at the moment in scripts/Makefile.headersinst
relies on the (handy) GNU extension where you can escape ERE's in an
otherwise BRE without using the GNU -r option. The following patch
replaces this "\+" usage with a functionally equivalent POSIX BRE compliant
"\{1,\}". Tested with `make headers_install` against blackfin/x86_64/i386
targets.

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

note:
- checks for documentation for new __setup calls
- clearer reporting where braces and parenthesis are involved
- reports for closing brace and semi-colon spacing
- reports on unwanted externs
This patch includes an update to the documentation on checkpatch.pl
itself to clarify when it should be used and to indicate that it
is not intended as the final arbitor of style.

A bug in headers_install for ARCH=x86_64 yields an asm/ directory full of
files all of which are using the same #ifdef guard, "__ASM_STUB_" with no
postfix. So the second and later asm files #included in the same C file
(often through standard headers like ioctl.h) yields no symbols.

Not all the world is an i386. Many architectures need 64-bit arguments to be
aligned in suitable pairs of registers, and the original
sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an
argument register for padding after the first integer. Since we don't
normally have more than 6 arguments for system calls, that left no room for
the final argument on some architectures.
Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which
all fits nicely. In fact, ARM already had that, but called it
sys_arm_sync_file_range. Move it to fs/sync.c and rename it, then implement
the needed compatibility routine. And stop the missing syscall check from
bitching about the absence of sys_sync_file_range() if we've implemented
sys_sync_file_range2() instead.
Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.

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.

Throughout the kernel there are a few legitimite references
to init or exit sections. Most of these are covered by the
patterns included in modpost but a few nees special attention.
To avoid hardcoding a lot of function names in modpost introduce
a marker so relevant function/data can be marked.
When modpost see a reference to a init/exit function from
a function/data marked no warning will be issued.

WARNING: mm/built-in.o - Section mismatch: reference to .init.text:set_up_list3s from .text between 'kmem_cache_create' (at offset 0x18a6b) and 'cache_reap'
Now modpost can detect "kernel_init" name (and whitelist it) and show
"set_up_list3s" name.

Change modpost section mismatch warnings to be less confusing;
model them on the binutils linker warnings which we all know how
to interpret.
Also, fix the wrong ordering of arguments for the final case -
fromsec and refsymname were reversed.

The check-lxdialog.sh script searches for "libFOO.so" which fails on OS X, due
to their special naming of libraries like "libfoo.dylib". This patch turns
the curses lib search into extensible loops and adds dylib as a valid
extension.

POSIX says limits.h defines PATH_MAX so we should include it (which fixes
compiling on some systems like OS X).

Since the devices may have multiple (or none) compatible properties,
the uevent generated internally by the kernel may have multiple
"C..." entries. So the MODALIAS stored in the module must have
wilcard before and after the compatible entry.
Also, if the 'compatible' field is not used for matching, there
will be no 'C' and that must handled as well.
The previous code handled all those case incorrectly and it
"mostly" worked ... but not always.
