base patch to implement 'jump labeling'. Based on a new 'asm goto' inline assembly gcc mechanism, we can now branch to labels from an 'asm goto' statment. This allows us to create a 'no-op' fastpath, which can subsequently be patched with a jump to the slowpath code. This is useful for code which might be rarely used, but which we'd like to be able to call, if needed. Tracepoints are the current usecase that these are being implemented for. Acked-by: NDavid S.

It is now possible to assign options to AS and CC on the command line - which is only used for built-in code. {A,C}FLAGS_KERNEL was used both in the top-level Makefile in the arch makefiles, thus users had no way to specify additional options to AS, CC without overriding the original value. Introduce a new set of variables KBUILD_{A,C}FLAGS_KERNEL that is used by arch specific files and free up {A,C}FLAGS_KERNEL so they can be assigned on the command line. All arch Makefiles that used the old variables has been updated.

It is now possible to assign options to AS, CC and LD on the command line - which is only used when building modules. {A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile in the arch makefiles, thus users had no way to specify additional options to AS, CC, LD when building modules without overriding the original value. Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE that is used by arch specific files and free up {A,C,LD}FLAGS_MODULE so they can be assigned on the command line. All arch Makefiles that used the old variables has been updated. Note: Previously we had a MODFLAGS variable for both AS and CC. But in favour of consistency this was dropped. So in some cases arch Makefile has one assignmnet replaced by two assignmnets. Note2: MODFLAGS was not documented and is dropped without any notice. I do not expect much/any breakage from this.

Newer gcc has a -femit-struct-debug-baseonly option that dramatically reduces the size of object files with debug info. What it does is to only emit type information for structures when the structures are defined in the same file or in a header file. This means the type information for most headers are not included. This is not good when the type information is actually needed (e.g. with kgdb or systemtap) But often kernel hackers only care about line numbers and don't need all the type information anyways. In this case setting the option can be a big win: A build dir for a specific x86-64 configuration with gcc 4.5 shrunk from 2.3G to 1.2G. The compilation was also nearly a minute faster.

Now that we run scripts/setlocalversion during every build, it makes sense to move all the localversion logic there. This cleans up the toplevel Makefile and also makes sure that the script is called only once in 'make prepare' (previously, it would be called every time due to a variable expansion in an ifneq statement). No user-visible change is intended, unless one runs the setlocalversion script directly.

In the commit below the version string handling was modified, adding a '+' where no other version information was supplied: commit 85a256d8 Author: David Rientjes <rientjes@google.com> Date: Wed Jan 13 13:01:05 2010 -0800 From the commit the intent was as below: - when CONFIG_LOCALVERSION_AUTO is disabled, a `+' is appended if the repository has been revised beyond a tagged commit and LOCALVERSION= was not passed to "make". However if the user supplies an empty LOCALVERSION on the command line the plus suffix is still added. This form is useful in the case where the build environment knows that the version as specified is correct and complete but does not correspond to a specific tag. This patch changes the implementation to match the documentation such that specifying LOCALVERSION= on the build line is sufficient to suppress any suffix.

A 'coccicheck' target is added. It can be called with four different modes. Each one generates a different kind of output, i.e. context, patch, org, report, according to the corresponding mode to be activated. The new target calls the 'coccicheck' front-end in the 'scripts' directory with the MODE argument. Every SmPL file in the subdirectories of 'scripts/coccinelle' is then given to the front-end and applied to the entire source tree. The four modes behave as follows: 'report' generates a list in the following format: file:line:column-column: message 'patch' proposes a fix, when possible. 'context' highlights lines of interest and their context in a diff-like style. Lines of interest are indicated with '-'. 'org' generates a report in the Org mode format of Emacs.
