* Fix MIPS cross-compile problemRalf Baechle2008-07-16
| | | | | | | | | | | | | | | | | | | | | | Crosscompiling on a Fedora 9 machine running gcc 4.3.0 as its host compiler and gcc 3.4.6 for the mips-linux target results in the following build error: $ make malta_defconfig $ make cc1: error: unrecognized command line option "-fno-stack-protector" scripts/kconfig/conf -s arch/mips/Kconfig cc1: error: unrecognized command line option "-fno-stack-protector" The arch Makefile is included too late so the host compiler is feature tested, not the crosscompiler as intended and thus the Makefile applies adds -fno-stack-protector to crosscompiler's flags which fails for gcc 3.4.6. The bug was introduced by e06b8b98da071f7dd78fb7822991694288047df0 in 2.6.25; 35bb5b1e0e84cfa1a8906f7e6a77f391ff315791 did add more flags testing before the arch Makefile inclusion.

| | | * firmware: Add firmware installation to modules_install, add firmware_installDavid Woodhouse2008-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For 'make modules_install', install any firmware required by the modules which are being installed. Also add a 'make firmware_install' target which doesn't depend on the configuration, but installs _all_ available in-kernel-tree firmware into $(INSTALL_FW_PATH), which defaults to /lib/firmware. This is intended for distributors to make arch-independent (and config-independent) packages containing firmware. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

The ftrace routine will then call a registered function if a function happens to be registered. [ This code has been highly hacked by Steven Rostedt and Ingo Molnar, so don't blame Arnaldo for all of this ;-) ] Update: It is now possible to register more than one ftrace function. If only one ftrace function is registered, that will be the function that ftrace calls directly. If more than one function is registered, then ftrace will call a function that will loop through the functions to call.

* kbuild: show defconfig subdirs in make helpSegher Boessenkool2008-04-28
| | | | | | | | | | | | | | | | | | | | PowerPC will start moving board defconfigs into subarch-specific subdirs soon. "make help" currently does not look in subdirs to find the defconfigs to show. This is partially a good thing, since there are way too many defconfigs for one list. This patch makes the main "make help" display something like help-40x - Show 40x-specific targets help-44x - Show 44x-specific targets help-boards - Show all of the above and wires up stuff so those new help-* commands actually work.

* Add option to enable -Wframe-larger-than= on gcc 4.4Andi Kleen2008-04-25
| | | | | | | | | | | | | | | | | | | | | | Add option to enable -Wframe-larger-than= on gcc 4.4 gcc mainline (upcoming 4.4) added a new -Wframe-larger-than=... option to warn at build time about too large stack frames. Add a config option to enable this warning, since this very useful for the kernel. I choose (somewhat arbitarily) 2048 as default warning threshold for 64bit and 1024 as default for 32bit architectures. With some research and fixing all the code for smaller values these defaults should be probably lowered. With the default allyesconfigs have some new warnings, but I think that is all code that should be just fixed. At some point (when gcc 4.4 is released and widely used) this should obsolete make checkstack Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

* kbuild: soften modpost checks when doing cross buildsSam Ravnborg2008-03-23
| | | | | | | | | | | | | | | | The module alias support in the kernel have a consistency check where it is checked that the size of a structure in the kernel and on the build host are the same. For cross builds this check does not make sense so detect when we do cross builds and silently skip the check in these situations. This fixes a build bug for a wireless driver when cross building for arm.

This was done to let modpost report section mismatch bugs even when the final link failed. Originally I had expected the dependency of $(kallsyms.o) to cover this but it turns out that we need to be even more explicit.

Some analysis later.. it turns out that the following line in the top level Makefile, added by you in October 2007, entirely disables CONFIG_CC_STACKPROTECTOR ;( With this line removed the exploit will be nicely stopped. CFLAGS += $(call cc-option, -fno-stack-protector) Now I realize that certain distros have patched gcc to compensate for their lack of distro wide CFLAGS, and it's great to work around that... but would there be a way to NOT disable this for CONFIG_CC_STACKPROTECTOR please? It would have made this exploit not possible for those kernels that enable this feature (and that includes distros like Fedora) === Move the assignment to KBUILD_CFLAGS up before including the arch specific Makefile so arch makefiles may override the setting.
