akpm@linux-foundation.org de323f22a8 headers_check: better search for functions in headers
Some headers don't bother with "extern" in function prototypes, which
results in said prototypes being unnoticed and exported to userland.

This patch slightly improves detection of such cases by checking for C
type names as well in the beginning of a line.

Julia Lawall a1087ef6ab scripts/coccinelle: update for compatability with Coccinelle 0.2.4
For doubleinit.cocci, Coccinelle 0.2.4 requires a comma after ... in a
field list.  Coccinelle also now behaves gracefully when a definition is
provided for a virtual that doesn't exist, so there is no need for the
semantic patch code to check for this case.

Updated the documentation to reflect the fact that the best results will
now be obtained with Coccinelle version 0.2.4 or later.

John Reiser e63233f75a ftrace: Have recordmcount honor endianness in fn_ELF_R_INFO

forgot about cross-platform endianness.

Thank you to Arnaud for supplying before+after data files do_mounts*.o.

This fixes a MIPS build failure triggered by recordmcount.

Uwe Kleine-König 0a18a9386c tags: put function prototypes back!
Commit 7db86dc (ctags: usability fix) removed function prototypes from
tags file claiming "It makes no real sense to include function
prototypes".
But it is useful for quickly determining which header file developer
needs to include to fix compilation.

Now if someone wants to remove forward declarations (which I agree are
baggage), write a postprocessing script.

Asbjoern Sloth Toennesen 10f26fa642 kbuild, deb-pkg: select userland architecture based on UTS_MACHINE
Instead of creating the debian package for the compiling userland,
create it for a userland matching the kernel thats being compiled.

This patch supports all Lenny release architectures,
and Linux-based architecture candidates for Squeeze.

If it can't find a proper Debian userspace it displays a warning,
and fallback to let deb-gencontrol use the host's userspace arch.

Eg. with this patch the following make command:

	make ARCH=i386 deb-pkg

will output an i386 Debian package instead of an amd64 one,
when run on an amd64 machine.

scripts/kernel-doc was leaving unescaped '<', '>', and '&' in

Convert these characters to "&lt;", "&gt;", and "&amp;" as needed

Most of the conversion was already done; complete it just before

Wu Zhangjin 45677454dd ftrace: Speed up recordmcount
cmd_record_mcount is used to locate the _mcount symbols in the object
files, only the files compiled with -pg has the _mcount symbol, so, it
is only needed for such files, but the current cmd_record_mcount is used
for all of the object files, so, we need to fix it and speed it up.

Since -pg may be removed by the method used in kernel/trace/Makefile:

ORIG_CFLAGS := $(KBUILD_CFLAGS)
KBUILD_CFLAGS = $(subst -pg,,$(ORIG_CFLAGS))

Or may be removed by the method used in arch/x86/kernel/Makefile:

CFLAGS_REMOVE_file.o = -pg

So, we must check the last variable stores the compiling flags, that is
c_flags(Please refer to cmd_cc_o_c and rule_cc_o_c defined in
scripts/Makefile.build) and since the CFLAGS_REMOVE_file.o is already
filtered in _c_flags(Please refer to scripts/Makefile.lib) and _c_flags
has less symbols, therefore, we only need to check _c_flags.

---------------
Changes from v1:

  o Don't touch Makefile for CONFIG_FTRACE_MCOUNT_RECORD is enough
  o Use _c_flags intead of KBUILD_CFLAGS to cover CONFIG_REMOVE_file.o = -pg

Eric Dumazet 8af27e1dc4 fixdep: use hash table instead of a single array
I noticed fixdep uses ~2% of cpu time in kernel build, in function
use_config()

fixdep spends a lot of cpu cycles in linear searches in its internal
string array. With about 400 stored strings per dep file, this begins to
be noticeable.

Convert fixdep to use a hash table.
