Functions used for PCI fixups (like DECLARE_PCI_FIXUP_HEADER) are often
marked __init. This is okay as long as nobody is using PCI hotplug.
However if one does execute
| echo 1 > /sys/bus/pci/rescan
and we hit a module which is marked __init istead of __devinit then we
go boom because the code is removed after the kernel booted. This patch
help to see those section mismatches.

Currently, scripts/config removes the leading double-quote from
string options, but leaves the trailing double-quote.
Also, double-quotes in a string are escaped, but scripts/config
does not unescape those when printing
Finally, scripts/config does not escape double-quotes when setting
string options.
Eg. the current behavior:
$ grep -E '^CONFIG_FOO=' .config
CONFIG_FOO="Bar \"Buz\" Meh"
$ ./scripts/config -s FOO
Bar \"Buz\" Meh"
$ ./scripts/config --set-str FOO 'Alpha "Bravo" Charlie'
$ grep -E '^CONFIG_FOO=' .config
CONFIG_FOO="Alpha "Bravo" Charlie"
Fix those three, giving this new behavior:
$ grep -E '^CONFIG_FOO=' .config
CONFIG_FOO="Bar \"Buz\" Meh"
$ ./scripts/config -s FOO
Bar "Buz" Meh
$ ./scripts/config --set-str FOO 'Alpha "Bravo" Charlie'
$ grep -E '^CONFIG_FOO=' .config
CONFIG_FOO="Alpha \"Bravo\" Charlie"

Prevent subtle surprises to both people working on the kconfig code
and people using make allnoconfig allyesconfig allmoconfig and
randconfig by only attempting to read a config file if
KCONFIG_ALLCONFIG is set.
Common sense suggests attempting to read the extra config files does
not make sense unless requested. The documentation says the code
won't attempt to read the extra config files unless requested.
Current usage does not appear to include people depending on the code
reading the config files without the variable being set So do the
simple thing and stop reading config files when passed
all{no,yes,mod,def,rand}config unless KCONFIG_ALLCONFIG environment
variable is set.

- Only try to read the file specified if KCONFIG_ALL_CONFIG is set to
something other than the empty string or "1".
- Don't use stat to check the name passed to conf_read_simple so that
zconf_fopen can find the file in the current directory or in SRCTREE
removing a extremely source of confusing failure, where KCONFIG_ALL_CONFIG
was not interpreted with respect to the directory make was called in.
- If conf_read_simple fails complain clearly and stop processing.
Allowing the simple debugging of typos.
- Clearly document the behavior so it is clear to users which
values are treated as flags and which values are treated as
filenames.

Move the final link of vmlinux to a script to improve
readability and maintainability of the code.
The Makefile fragments used to link vmlinux has over the
years seen far too many changes and the logic had become
hard to follow.
As the process by nature is serialized there was
nothing gained including this in the Makefile.
"um" has special link requirments - and the
only way to handle this was to hard-code the linking
of "um" in the script.
This was better than trying to modularize it only for the
benefit of "um" anyway.
The shell script has been improved after input from:

Pull the MCA deletion branch from Paul Gortmaker:
"It was good that we could support MCA machines back in the day, but
realistically, nobody is using them anymore. They were mostly limited
to 386-sx 16MHz CPU and some 486 class machines and never more than
64MB of RAM. Even the enthusiast hobbyist community seems to have
dried up close to ten years ago, based on what you can find searching
various websites dedicated to the relatively short lived hardware.
So lets remove the support relating to CONFIG_MCA. There is no point
carrying this forward, wasting cycles doing routine maintenance on it;
wasting allyesconfig build time on validating it, wasting I/O on git
grep'ping over it, and so on."
Let's see if anybody screams. It generally has compiled, and James
Bottomley pointed out that there was a MCA extension from NCR that
allowed for up to 4GB of memory and PPro-class machines. So in *theory*
there may be users out there.
But even James (technically listed as a maintainer) doesn't actually
have a system, and while Alan Cox claims to have a machine in his cellar
that he offered to anybody who wants to take it off his hands, he didn't
argue for keeping MCA support either.
So we could bring it back. But somebody had better speak up and talk
about how they have actually been using said MCA hardware with modern
kernels for us to do that. And David already took the patch to delete
all the networking driver code (commit a5e371f61ad3: "drivers/net:
delete all code/drivers depending on CONFIG_MCA").
* 'delete-mca' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux:
MCA: delete all remaining traces of microchannel bus support.
scsi: delete the MCA specific drivers and driver code
serial: delete the MCA specific 8250 support.
arm: remove ability to select CONFIG_MCA

Hardware with MCA bus is limited to 386 and 486 class machines
that are now 20+ years old and typically with less than 32MB
of memory. A quick search on the internet, and you see that
even the MCA hobbyist/enthusiast community has lost interest
in the early 2000 era and never really even moved ahead from
the 2.4 kernels to the 2.6 series.
This deletes anything remaining related to CONFIG_MCA from core
kernel code and from the x86 architecture. There is no point in
carrying this any further into the future.
One complication to watch for is inadvertently scooping up
stuff relating to machine check, since there is overlap in
the TLA name space (e.g. arch/x86/boot/mca.c).

Pull exception table generation updates from Ingo Molnar:
"The biggest change here is to allow the build-time sorting of the
exception table, to speed up booting. This is achieved by the
architecture enabling BUILDTIME_EXTABLE_SORT. This option is enabled
for x86 and MIPS currently.
On x86 a number of fixes and changes were needed to allow build-time
sorting of the exception table, in particular a relocation invariant
exception table format was needed. This required the abstracting out
of exception table protocol and the removal of 20 years of accumulated
assumptions about the x86 exception table format.
While at it, this tree also cleans up various other aspects of
exception handling, such as early(er) exception handling for
rdmsr_safe() et al.
All in one, as the result of these changes the x86 exception code is
now pretty nice and modern. As an added bonus any regressions in this
code will be early and violent crashes, so if you see any of those,
you'll know whom to blame!"
Fix up trivial conflicts in arch/{mips,x86}/Kconfig files due to nearby
modifications of other core architecture options.

x86 is now using relative rather than absolute addresses in its
exception table, so we add a sorter for these. If there are
relocations on the __ex_table section, they are redundant and probably
incorrect after the sort, so they are zeroed out leaving them valid
and consistent.
Also use the unaligned safe accessors from tools/{be,le}_byteshift.h

Most HID drivers do not need to know what bus driver is in use.
A generic group driver can drive any hid device, and the device
list should not need to be duplicated for each new bus.
This patch adds wildcard matching to the HID bus, simplifying device
list handling for group drivers.

HID devices are only partially presented to userland. Hotplugged
devices emit events containing a modalias based on the basic bus,
vendor and product entities. However, in practise a hid device can
depend on details such as a single usb interface or a particular item
in a report descriptor.
This patch adds a device group to the hid device id, and broadcasts it
using uevent and the device modalias. The module alias generation is
modified to match. As a consequence, a device with a non-zero group
will be processed by the corresponding group driver instead of by the
generic hid driver.

A new option is added to the relocs tool called '--realmode'.
This option causes the generation of 16-bit segment relocations
and 32-bit linear relocations for the real-mode code. When
the real-mode code is moved to the low-memory during kernel
initialization, these relocation entries can be used to
relocate the code properly.
In the assembly code 16-bit segment relocations must be relative
to the 'real_mode_seg' absolute symbol. Linear relocations must be
relative to a symbol prefixed with 'pa_'.
16-bit segment relocation is used to load cs:ip in 16-bit code.
Linear relocations are used in the 32-bit code for relocatable
data references. They are declared in the linker script of the
real-mode code.
The relocs tool is moved to arch/x86/tools/relocs.c, and added new
target archscripts that can be used to build scripts needed building
an architecture. be compiled before building the arch/x86 tree.
[ hpa: accelerating this because it detects invalid absolute
relocations, a serious bug in binutils 2.22.52.0.x which currently
produces bad kernels. ]

The symbol table on x86-64 starts to have entries that have names
like:
_GLOBAL__sub_I_65535_0___mod_x86cpu_device_table
They are of type STT_FUNCTION and this one had a length of 18. This
matched the device ID validation logic and it barfed because the
length did not meet the device type's criteria.
--------------------
FATAL: arch/x86/crypto/aesni-intel: sizeof(struct x86cpu_device_id)=16 is not a modulo of the size of section __mod_x86cpu_device_table=18.
Fix definition of struct x86cpu_device_id in mod_devicetable.h
--------------------
These are some kind of compiler tool internal stuff being emitted and
not something we want to inspect in modpost's device ID table
validation code.
So skip the symbol if it is not of type STT_OBJECT.

The BCJ filters were meant to be enabled already on these
archs, but the xz_wrap.sh script was buggy. Enabling the
filters should give smaller kernel images.
xz_wrap.sh will now use $SRCARCH instead of $ARCH to detect
the architecture. That way it doesn't need to care about the
subarchs (like i386 vs. x86_64) since the BCJ filters don't
care either.

Commit f02e8a6596b7 ("module: Sort exported symbols") sorts symbols
placing each of them in its own elf section. This sorting and merging
into the canonical sections are done by the linker.
Unfortunately modpost to generate Module.symvers file parses vmlinux.o
(which is not linked yet) and all modules object files (which aren't
linked yet). These aren't sanitized by the linker yet. That breaks
modpost that can't detect license properly for modules.
This patch makes modpost aware of the new exported symbols structure.
[ This above is a slightly corrected version of the explanation of the
problem, copied from commit 62a2635610db ("modpost: Fix modpost's
license checking V3"). That commit fixed the problem for module
object files, but not for vmlinux.o. This patch fixes modpost for
vmlinux.o. ]

wobbly about merging them because I'm wobbly about the overall

In some circumstances (eg when running a build in an emacs shell
buffer), I get a spew of messages like
grep: writing output: Broken pipe
from setlocalversion, because the "read" subshell apparently exits as
soon as it reads one line and gives EPIPE to grep. It's not clear to
me why this way of writing the check was used instead of just using
grep -q to suppress output, but unless there is some deep reason I
don't know, this way looks cleaner to me anyway, and gets rid of the
ugly message spew.
(I double checked at http://pubs.opengroup.org/onlinepubs/009604499/utilities/grep.html
and "grep -q" is specified in POSIX / SuS, so hopefully even people
cross-compiling the kernel on some bizarre host OS can't complain
about this change)

"echo -e" is a GNU extension. When cross-compiling the kernel on a
BSD-like operating system (Mac OS X in my case), this doesn't work.
One could install a GNU version of echo, put that in the $PATH before
the system echo and use "/usr/bin/env echo", but the solution with
printf is simpler.
Since it is no disadvantage on Linux, I hope that gets accepted even if
cross-compiling the Linux kernel on another Unix operating system is
quite a rare use case.
