Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

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.

kbuild: add machine size to CHECKFLAGS By default, sparse assumes a 64bit machine when compiled on x86-64 and 32bit when compiled on anything else. This can of course create all sort of problems for the other archs, like issuing false warnings ('shift too big (32) for type unsigned long'), or worse, failing to emit legitimate warnings. Fix this by adding the -m32/-m64 flag, depending on CONFIG_64BIT, to CHECKFLAGS in the main Makefile (and so for all archs). Also, remove the now unneeded -m32/-m64 in arch specific Makefiles.

kbuild: allow assignment to {A,C}FLAGS_KERNEL on the command line 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.

ia64: remove the hpsim platform The hpsim platform supports the HP IA64 simulator which was useful as a bring up platform. But it is fairly non-standard vs real IA64 system in that it for example doesn't support ACPI. It also comes with a whole bunch of simulator specific drivers. Remove it to simplify the IA64 port. Note that through a weird twist only them hpsim boot loader built the vmlinux.gz file, so the makefile targets for that are moved to the main ia64 Makefile now.

kbuild: fix broken builds because of GZIP,BZIP2,LZOP variables Redefine GZIP, BZIP2, LZOP variables as KGZIP, KBZIP2, KLZOP resp. GZIP, BZIP2, LZOP env variables are reserved by the tools. The original attempt to redefine them internally doesn't work in makefiles/scripts intercall scenarios, e.g., "make GZIP=gzip bindeb-pkg" and results in broken builds. There can be other broken build commands because of this, so the universal solution is to use non-reserved env variables for the compression tools.

kbuild: enable 'make CFLAGS=...' to add additional options to CC The variable CFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour.

One usecase is when trying to find gcc bugs but other use cases has been requested too.

Construct init thread stack in the linker script rather than by union Construct the init thread stack in the linker script rather than doing it by means of a union so that ia64's init_task.c can be got rid of. The following symbols are then made available from INIT_TASK_DATA() linker script macro: init_thread_union init_stack INIT_TASK_DATA() also expands the region to THREAD_SIZE to accommodate the size of the init stack. init_thread_union is given its own section so that it can be placed into the stack space in the right order. I'm assuming that the ia64 ordering is correct and that the task_struct is first and the thread_info second.

ia64: remove support for machvecs The only thing remaining of the machvecs is a few checks if we are running on an SGI UV system. Replace those with the existing is_uv_system() check that has been rewritten to simply check the OEM ID directly. That leaves us with a generic kernel that is as fast as the previous DIG/ZX1/UV kernels, but can support all hardware. Support for UV and the HP SBA IOMMU is now optional based on new config options.
