4d634ca35a Merge branch 'rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull build system failure fix from Michal Marek:
 "This fixes build failure with newer gcc that adds some internal
  symbols that end in "__mod_*_device_table", but are not actually the
  tables themselves."

0db7bd8ca0 xz: Enable BCJ filters on SPARC and 32-bit x86
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.

e88aa7bbbe Fix modpost failures in fedora 17
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.

a959613533 Revert "kconfig: fix __enabled_ macros definition for invisible and un-selected symbols"
This reverts commit 953742c8fe.

Dumping two lines into autoconf.h for all existing Kconfig options
results in a giant file (~16k lines) we have to process each time we
compile something.  We've weaned IS_ENABLED() and similar off of
requiring the __enabled_ definitions so now we can revert the change
which caused all the extra lines.

258f742635 modpost: Fix modpost license checking of vmlinux.o
Commit f02e8a6596 ("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 62a2635610 ("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. ]

5d32c88f0b Merge branch 'akpm' (Andrew's patch-bomb)
Merge batch of fixes from Andrew Morton:
 "The simple_open() cleanup was held back while I wanted for laggards to
  merge things.

  I still need to send a few checkpoint/restore patches.  I've been
  wobbly about merging them because I'm wobbly about the overall
  prospects for success of the project.  But after speaking with Pavel
  at the LSF conference, it sounds like they're further toward
  completion than I feared - apparently davem is at the "has stopped
  complaining" stage regarding the net changes.  So I need to go back
  and re-review those patchs and their (lengthy) discussion."

7f3bd6c9cb setlocalversion: Use "grep -q" instead of piping output to "read dummy"
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)

875de98623 scripts/Kbuild.include: Fix portability problem of "echo -e"
"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.

ca56dc098c checkpatch: check for quoted strings broken across lines
checkpatch already makes an exception to the 80-column rule for quoted
strings, and Documentation/CodingStyle recommends not splitting quoted
strings across lines, because it breaks the ability to grep for the
string.  Rather than just permitting this, actively warn about quoted
strings split across lines.

Test case:

void context(void)
{
	struct { unsigned magic; const char *strdata; } foo[] = {
		{ 42, "these strings"
		      "do not produce warnings" },
		{ 256, "though perhaps"
		       "they should" },
	};
	pr_err("this string"
	       " should produce a warning\n");
	pr_err("this multi-line string\n"
	       "should not produce a warning\n");
	asm ("this asm\n\t"
	     "should not produce a warning");
}

Results of checkpatch on that test case:

WARNING: quoted string split across lines
+	       " should produce a warning\n");

Handle the [ A ... B ] form deeper into a definition, for example:

    static const unsigned char pci_irq_swizzle[2][PCI_MAX_DEVICES] = {
	    {0, 0, 0, 0, 0, 0, 0, 27, 27, [9 ... PCI_MAX_DEVICES - 1] = 0 },
	    {0, 0, 0, 0, 0, 0, 0, 29, 29, [9 ... PCI_MAX_DEVICES - 1] = 0 },
    };

11232688ec checkpatch.pl: be silent when -q and --ignore is given
Fix checkpatch.pl when both -q and --ignore are given and prevents it from
printing a

NOTE: Ignored message types: blah

messages.

E.g., if I use -q --ignore PREFER_PACKED,PREFER_ALIGNED, i see:

NOTE: Ignored message types: PREFER_ALIGNED PREFER_PACKED

It makes no sense to print this when -q is given.

d1fe9c099c checkpatch: add some --strict coding style checks
Argument alignment across multiple lines should match the open
parenthesis.

Logical continuations should be at the end of the previous line, not the
start of a new line.

These are not required by CodingStyle so make the tests active only when
using --strict.

Improved by some examples from Bruce Allen.

1e73fde581 Merge branch 'rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
three kbuild fixes for 3.3:
 - make deb-pkg symlink race fix.
 - make coccicheck fix.
 - Dropping the check for modutils.  This is not a regression, but
   allows the module-init-tools replacement kmod work with the 3.3
   kernel.

* 'rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  coccicheck: change handling of C={1,2} when M= is set
  builddeb: Don't create files in /tmp with predictable names
  kbuild: do not check for ancient modutils tools
