Take the first config fragment and use it verbatim as the initial config
set. This avoids running the verification loop for the first file, as
nothing has actually been merged at this point. This significantly
increases performance for large config fragments.

Some versions of ARM GCC which do support asm goto, do not support
the %c specifier. Since we need the %c to support jump labels
on ARM, detect that too in the asm goto detection script to avoid
build errors with these versions.

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");
total: 0 errors, 1 warnings, 15 lines checked

Add some more subjective --strict tests.
Add a test for block comments that start with a blank line followed only
by a line with just the comment block initiator. Prefer a blank line
followed by /* comment...
Add a test for unnecessary spaces after a cast.
Add a test for symmetric uses of braces in if/else blocks.
If one branch needs braces, then all branches should use braces.

With any very high precedence operator it is not necessary to enforce
additional parentheses around simple negated expressions. This prevents
us requesting further perentheses around the following:
#define PMEM_IS_FREE(id, index) !(pmem[id].bitmap[index].allocated)
For now add logical and bitwise not and unary minus.

Adjacent strings indicate concatentation, therefore look at identifiers
directly adjacent to literal strings as strings too. This allows us to
better detect the form below and accept it as a simple constant:
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt

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.

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.

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
