[PATCH] biarch compiler support for i386 This allows the i386 architecture to be built on a system with a biarch compiler that defaults to x86-64, merely by specifying ARCH=i386.

[PATCH] i386: Relocatable kernel support This patch modifies the i386 kernel so that if CONFIG_RELOCATABLE is selected it will be able to be loaded at any 4K aligned address below 1G. The technique used is to compile the decompressor with -fPIC and modify it so the decompressor is fully relocatable. For the main kernel relocations are generated. Resulting in a kernel that is relocatable with no runtime overhead and no need to modify the source code. A reserved 32bit word in the parameters has been assigned to serve as a stack so we figure out where are running. Signed-off-by: Eric W.

[PATCH] uml: reuse i386 cpu-specific tuning Make UML share the underlying cpu-specific tuning done on i386. Actually, for now many config options aren't used a lot - but that can be done later. Also, UML relies on GCC optimization for things like memcpy and such more than i386, so specifying the correct -march and -mtune should be enough. Later, we may want to correct some other stuff. For instance, since FPU context switching, for us, is done (at least partially, i.e. between our kernelspace and userspace) by the host, we may allow usage of FPU operations by GCC. This doesn't hold for kernelspace vs. kernelspace, but we don't support preemption.

[PATCH] x86: Use -maccumulate-outgoing-args This avoids some problems with gcc 4.x and earlier generating invalid unwind information. In 4.1 the option is default when unwind information is enabled.

[PATCH] enable unit-at-a-time optimisations for gcc4 Allow gcc4 compilers to optimize unit-at-a-time. This flag enables gcc to "see" the entire C file before making optimisation decisions such as inline, which results in gcc making better decisions. One of the immediate effects of this is that static functions that are used only once now get inlined. gcc 3.4 has this flag as well, however gcc 3.x have a problem with inlining and stacks and as a result, enabling this flag there would cause excessive and unacceptable stack use. This problem is fixed in the gcc 4.x series. The x86-64 architecture already enables this feature so it's well tested already.

[PATCH] i386/x86-64: Work around gcc bug with noreturn functions in unwinder Current gcc generates calls not jumps to noreturn functions. When that happens the return address can point to the next function, which confuses the unwinder. This patch works around it by marking asynchronous exception frames in contrast normal call frames in the unwind information. Then teach the unwinder to decode this. For normal call frames the unwinder now subtracts one from the address which avoids this problem. The standard libgcc unwinder uses the same trick. It doesn't include adjustment of the printed address (i.e. for the original example, it'd still be kernel_math_error+0 that gets displayed, but the unwinder wouldn't get confused anymore. This only works with binutils 2.6.17+ and some versions of H.J.Lu's 2.6.16 unfortunately because earlier binutils don't support .cfi_signal_frame [AK: added automatic detection of the new binutils and wrote description] Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Andi Kleen <ak@suse.de>

kbuild: change kbuild to not rely on incorrect GNU make behavior The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

[PATCH] kbuild/i386: re-introduce dependency on vmlinux for install target, and add kernel_install Removing the dependency on vmlinux for the install target raised a few complaints, so instead a new target i added: kernel_install. kernel_install will install the kernel just like the ordinary install target. The only difference is that install has a dependency on vmlinux, kernel_install does not. Therefore kernel_install is the best choice when accessing the kernel over a NFS mount or as another user. kernel_install is similar to modules_install in the fact that neither does a full kernel compile before performing the install. In this way they are good for root use. Also added back the dependency on vmlinux for the install target so peoples scripts are no longer broken.
