* sparc: Kill PROM console driver.David S. Miller2009-09-151-1/+0
| | | | | | | | | | | | | | | | Many years ago when this driver was written, it had a use, but these days it's nothing but trouble and distributions should not enable it in any situation. Pretty much every console device a sparc machine could see has a bonafide real driver, making the PROM console hack unnecessary. If any new device shows up, we should write a driver instead of depending upon this crutch to save us. We've been able to take care of this even when no chip documentation exists (sunxvr500, sunxvr2500) so there are no excuses. Signed-off-by: David S. Miller <davem@davemloft.net>

The code to find the selects of a config is after the code that adds the depends. But if a config needed selects but had no dependencies, it would not be set.

For those that install a kernel to a new box using the config file from the distribution know that it can take forever to compile the kernel. Making a custom config file that will still boot your box, but bring down the compile time of the kernel can be quit painful, and to ask someone that reported a bug to do this can be a large burdon since that person may not even know how to build a kernel. This script will perform "lsmod" to find all the modules loaded on the current running system. It will read all the Makefiles to map which CONFIG enables a module. It will read the Kconfig files to find the dependencies and selects that may be needed to support a CONFIG. Finally, it reads the .config file and removes any module "=m" that is not needed to enable the currently loaded modules. The output goes to standard out. Here's a way to run the script. From the Linux directory that holds a distribution .config. $ scripts/kconfig/streamline_config.pl arch/x86/Kconfig > config-sl $ mv .config config-save $ mv config-sl .config $ make oldconfig Now you have a .config that will still build all your modules, but also take much less time to build the kernel.

Well we tracked it down and it is powerpc64 specific. 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 <.LM93_IN_FROM_REG>: 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.

| * | | | ftrace: Only update $offset when we update $ref_funcMatt Fleming2009-07-231-1/+2

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.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* gcov: add gcov profiling infrastructurePeter Oberparleiter2009-06-181-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 debugfs Note 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).
