Roland Dreier found that a section that contained only a weak
function in one of the staging drivers and this caused
recordmcount.pl to spit out a warning and fail.Although it is strange that a driver would have a weak function, and
this function only be used in one place, it should not be something
to make recordmcount.pl fail.This patch fixes the issue in a simple manner: if only weak
functions exist in a section, then that section will not be
recorded.Reported-by: Roland Dreier

Seems that in drivers/hwmon/lm93.c there's a function called:
LM93_IN_FROM_REG()
But PPC64 has function descriptors and the real function names (the ones
you see in objdump) start with a '.'. Thus this in objdump you have:Disassembly of section .text:
0000000000000000 :
0: 7c 08 02 a6 mflr r0
4: fb 81 ff e0 std r28,-32(r1)The function name used is .LM93_IN_FROM_REG. But gcc considers symbols
that start with ".L" as a special symbol that is used inside the assembly
stage.The nm passed into recordmcount uses the --synthetic option which shows
the ".L" symbols (my runs outside of the build did not include the
--synthetic option, so my older patch worked). We see the function as a
local.Now to capture all the locations that use "mcount" we need to have a
reference to link into the object file a list of mcount callers. We need a
reference that will not disappear. We try to use a global function and if
that does not work, we use a local function as a reference. But to relink
the section back into the object, we need to make it global. In this case,
we run objcopy using --globalize-symbol and --localize-symbol to convert
the symbol into a global symbol, link the mcount list, then convert it
back to a local symbol.This works great except for this case. .L* symbols can not be converted
into a global symbol, and the mcount section referencing it will remain
unresolved.Reported-by: Dave Airlie

The value of $offset should be the offset of $ref_func from the
beginning of the object file. Therefore, we should set both variables
together.This fixes a bug I was hitting on sh where $offset (which is used to
calcualte the addends for the __mcount_loc entries) was being set
multiple times and didn't correspond to $ref_func's offset in the object
file. The addends in __mcount_loc were calculated incorrectly, resulting
in ftrace dynamically modifying addresses that weren't mcount call
sites.Signed-off-by: Matt Fleming

When building with a 4.1.x compiler on powerpc64 (at least) we get this
error:drivers/video/logo/logo_linux_mono.c:81: error: logo_linux_mono causes a section type conflict
This was introduced by commit ae52bb2384f721562f15f719de1acb8e934733cb
("fbdev: move logo externs to header file"). This is a partial revert of
that commit sufficient to not hit the compiler bug.Also convert _clut arrays from __initconst to __initdata.
Sam said:
Al analysed this some time ago. When we say something is const then
_sometimes_ gcc annotate the section as const(?) - sometimes not. So if
we have two variables/functions annotated __*const and gcc decides to
annotate the section const only in one case we get a section type
conflict.Signed-off-by: Stephen Rothwell

Enable the use of GCC's coverage testing tool gcov [1] with the Linux
kernel. gcov may be useful for:* debugging (has this code been reached at all?)
* test improvement (how do I change my test to cover these lines?)
* minimizing kernel configurations (do I need this option if the
associated code is never run?)The profiling patch incorporates the following changes:
* change kbuild to include profiling flags
* provide functions needed by profiling code
* present profiling data as files in debugfsNote that on some architectures, enabling gcc's profiling option
"-fprofile-arcs" for the entire kernel may trigger compile/link/
run-time problems, some of which are caused by toolchain bugs and
others which require adjustment of architecture code.For this reason profiling the entire kernel is initially restricted
to those architectures for which it is known to work without changes.
This restriction can be lifted once an architecture has been tested
and found compatible with gcc's profiling. Profiling of single files
or directories is still available on all platforms (see config help
text).[1] http://gcc.gnu.org/onlinedocs/gcc/Gcov.html

The page allocation failure messages include a line that looks like
page allocation failure. order:1, mode:0x4020
The mode is easy to translate but irritating for the lazy and a bit error
prone. This patch adds a very simple helper script gfp-translate for the
mode: portion of the page allocation failure messages. An example usage
looks likemel@machina:~/linux-2.6 $ scripts/gfp-translate 0x4020
Source: /home/mel/linux-2.6
Parsing: 0x4020
#define __GFP_HIGH (0x20) /* Should access emergency pools? */
#define __GFP_COMP (0x4000) /* Add compound page metadata */The script is not a work of art but it has come in handy for me a few
times so I thought I would share.[akpm@linux-foundation.org: clarify an error message]
