When resolving symbol names from addresses with aliased symbol names,
kallsyms_lookup always returns the first symbol, even if it is a weak
symbol.
This patch changes this by sorting the symbols with the weak symbols last
before feeding them to the kernel. This way the kernel runtime isn't
changed at all, only the kallsyms build system is changed.
Another side effect is that the symbols get sorted by address, too. So,
even if future binutils version have some bug in "nm" that makes it fail to
correctly sort symbols by address, the kernel won't be affected by this.
Mathieu says:
I created a module in LTTng that uses kallsyms to get the symbol
corresponding to a specific system call address. Unfortunately, all the
unimplemented syscalls were all referring to the (same) weak symbol
identifying an unrelated system call rather that sys_ni (or whatever
non-weak symbol would be expected). Kallsyms was dumbly returning the first
symbol that matched.
This patch makes sure kallsyms returns the non-weak symbol when there is
one, which seems to be the expected result.

When passing a zero address to kallsyms_lookup(), the kernel thought it was
a valid kernel address, even if it is not. This is because is_ksym_addr()
called is_kernel_extratext() and checked against labels that don't exist on
many archs (which default as zero). Since PPC was the only kernel which
defines _extra_text, (in 2005), and no longer needs it, this patch removes
_extra_text support.

If there is a mixture of specifying sections for code in gcc
and assembler then if the assembler code do not add
the "ax" flags the linker will see this as two different sections
and generate unique sections for each. ld does so by adding a dot
and a number.
Teach modpost to warn if a section shows up that match this
pattern - but do this only for non-debug sections.
It will result in warnings like this:
WARNING: vmlinux.o (.sched.text.1): unexpected section name.
The (.[number]+) following section name are ld generated and not expected.
Did you forget to use "ax"/"aw" in a .S file?
Note that for example <linux/init.h> contains
section definitions for use in .S files.
All warnings seen with a defconfig build for:
x86 (32+64bit) and sparc64 has been fixed (via respective maintainers).

Introducing separate sections for __dev* (HOTPLUG),
__cpu* (HOTPLUG_CPU) and __mem* (MEMORY_HOTPLUG)
allows us to do a much more reliable Section mismatch
check in modpost. We are no longer dependent on the actual
configuration of for example HOTPLUG.
This has the effect that all users see much more
Section mismatch warnings than before because they
were almost all hidden when HOTPLUG was enabled.
The advantage of this is that when building a piece
of code then it is much more likely that the Section
mismatch errors are spotted and the warnings will be
felt less random of nature.

Change the logic in modpost so we identify all the
bad combinations of sections that refer to other

Compared to the previous approach we are much less
dependent on knowledge of what additional sections
the tool chain uses and thus we can keep the false

The implmentation is changed to use a table based
lookup and we now check all combinations in first
pass so we no longer need separate passes for init

Switch from doing our own parsing of command line arguments to
using getopt(3) to do it. Aside from simplifying things, this allows us to
specify multiple arguments; the old code could only accept two arguments
(input_mode and kconfig name).
Note some subtle changes:
- The argument '-?' is no longer supported.
- '-h' is not treated as an error, so output goes to stdout, and we
exit with '0'.
- There is no compatibility checking amongst arguments; the last option
will simply override earlier options. For example, 'conf -n -y foo'
is perfectly valid now (input_mode will be set_yes). Previously, that
would have been an error ("can't find file -y").

When multiple built-in modules (especially drivers) provide the same
capability, they're prioritized by link order specified by the order
listed in Makefile. This implicit ordering is lost for loadable
modules.
When driver modules are loaded by udev, what comes first in
modules.alias file is selected. However, the order in this file is
indeterministic (depends on filesystem listing order of installed
modules). This causes confusion.
The solution is two-parted. This patch updates kbuild such that it
generates and installs modules.order which contains the name of
modules ordered according to Makefile. The second part is update to
depmod such that it generates output files according to this file.
Note that both obj-y and obj-m subdirs can contain modules and
ordering information between those two are lost from beginning.
Currently obj-y subdirs are put before obj-m subdirs.
Sam Ravnborg cleaned up Makefile modifications and suggested using awk
to remove duplicate lines from modules.order instead of using separate
C program.

This version brings a new terse output mode as well as many improvements to
the unary detection and bare type regcognition. It also brings the usual
updates for false positives, though these seem to be slowing markedly
now that the unary detector is no longer just putting its finger in the
air and guessing. Of note:
- new --terse mode producing a single line per report
- loosening of the block brace checks
- new checks for enum/union/struch brace placements
- hugely expanded "bare type" detection
- checks for inline usage
- better handling of already open comment blocks
- handle patches which introduce or remove lines without newlines
Andy Whitcroft (19):

Simplify "make ARCH=x86" and fix kconfig so we again can set 64BIT in
all.config.
For a fix the diffstat is nice:
6 files changed, 3 insertions(+), 36 deletions(-)
The patch reverts these commits:
- 0f855aa64b ("kconfig: add helper to set
config symbol from environment variable")
- 2a113281f5 ("kconfig: use $K64BIT to
set 64BIT with all*config targets")
Roman Zippel pointed out that kconfig supported string compares so
the additional complexity introduced by the above two patches were
not needed.
With this patch we have following behaviour:
# make {allno,allyes,allmod,rand}config [ARCH=...]
option \ host arch | 32bit | 64bit
=====================================================
./. | 32bit | 64bit
ARCH=x86 | 32bit | 32bit
ARCH=i386 | 32bit | 32bit
ARCH=x86_64 | 64bit | 64bit
The general rule are that ARCH= and native architecture takes
precedence over the configuration.
So make ARCH=i386 [whatever] will always build a 32-bit kernel
no matter what the configuration says. The configuration will
be updated to 32-bit if it was configured to 64-bit and the
other way around.
This behaviour is consistent with previous behaviour so no
suprises here.
make ARCH=x86 will per default result in a 32-bit kernel but as
the only ARCH= value x86 allow the user to select between 32-bit
and 64-bit using menuconfig.

After unification of the Kconfig files and
introducing K64BIT support in kconfig
it required only trivial changes to enable
"make ARCH=x86".
With this patch you can build for x86_64 in several ways:
1) make ARCH=x86_64
2) make ARCH=x86 K64BIT=y
3) make ARCH=x86 menuconfig
=> select 64-bit
Likewise for i386 with the addition that
i386 is default is you say ARCH=x86.

The variable K64BIT can now be used to select the
value of CONFIG_64BIT.
This is for example useful for powerpc to generate
allmodconfig for both bit sizes - like this:
make ARCH=powerpc K64BIT=y
make ARCH=powerpc K64BIT=n
To use this the Kconfig file must use "64BIT" as the
config value to select between 32 and 64 bit.

This reverts commit a5bf3d891a.
David Brownell notes that this causes a regression visible in the
drivers/usb/gadget Kconfig file:
"That Kconfig hasn't changed (other than adding new drivers), and it's
worked that way for several years now ... so the issue seems to be
changes in menuconfig/kconfig/etc semantics.
The issue is that when USB_GADGET=m, it's no longer possible to
configure peripheral controller drivers as modules ... the
controller drivers can now only be configured for static linkage.
It should be making a choice of one of the controller drivers which
could work on the target system, and allow that driver to be linked
either as a module (ok iff USB_GADGET=m) or statically."
Reverting this commit resolves the problem, and also fixes a second
problem that David noticed: various dependent options couldn't be enabled.

When part of build an external module tree, modpost first reads in the
kernel's and then the external tree's Module.symvers files. From these files
it establishes a symbol => module mapping. When it later reads in each module
built and processes the symbols it finds, it discovers the symbol=>module
mapping from Module.symvers and leaves it as it is.
The problem comes with a module has been re-named or a symbol has moved from
one module to another, since the Module.symvers file was generated. modpost
does not update the symbol=>module mapping when it finds the new location of
the symbol when scanning the newly built modules. This results in the module
containing incorrect dependency information and the new Module.symvers file
written by modpost will also contain the incorrect mappings, perpetuating the
problem to the next build, and so on.
When building the out of kernel development tree for kernel subsystem, like
v4l-dvb or ALSA, deleting the external Module.symvers file before building
(which the kernel build system doesn't do and shouldn't be necessary anyway),
won't fix the problem. modpost still reads the kernel's Module.symvers, and
since we a building a kernel subsystem, it will define the same symbols as the
external modules.

Johannes Berg reports (Thanks!) that &struct names are not highlighted in
html output format when they are inside a DOC: block.
DOC: blocks were not escaped thru xml_escape() like other kernel-doc
comments were. Fixed that.
However, that left a problem with <p> ($blankline_html) being processed
thru xml_escape(), converting it to <p>, which isn't good for the
generated html output (the <p> should remain unchanged), so this patch also
introduces the notion of "local" kernel-doc meta-characters
('\\\\mnemonic:'), which are converted to html just before writing the
stream to its output file.
Please report any problems that you (anyone) see in "highlighting" in any
