* kbuild: Don't define ALIGN and ENTRY when preprocessing linker scripts.Tim Abbott2009-09-21
| | | | | | | | | | | | | | | | | | | | | | Adding a reference to <linux/linkage.h> to x86's <asm/cache.h> causes the x86 linker script to have syntax errors, because the ALIGN and ENTRY keywords get redefined to the assembly implementations of those. One could fix this by adjusting the include structure, but I think any solution based on that approach would be fragile. Currently, it is impossible when writing a header to do something different for assembly files and linker scripts, even though there are clearly cases where one wants them to define macros differently for the two (ENTRY being an excellent example). So I think the right solution here is to introduce a new preprocessor definition, called LINKER_SCRIPT that is set along with __ASSEMBLY__ for linker scripts, and to use that to not define ALIGN and ENTRY in linker scripts. I suspect we'll find other uses for this mechanism in the future. Signed-off-by: Tim Abbott <tabbott@ksplice.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0Sam Ravnborg2009-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Albin Tonnerre <albin.tonnerre@free-electrons.com> reported: Bash 4 filters out variables which contain a dot in them. This happends to be the case of CPPFLAGS_vmlinux.lds. This is rather unfortunate, as it now causes build failures when using SHELL=/bin/bash to compile, or when bash happens to be used by make (eg when it's /bin/sh) Remove the common definition of CPPFLAGS_vmlinux.lds by pushing relevant stuff to either Makefile.build or the arch specific kernel/Makefile where we build the linker script. This is also nice cleanup as we move the information out where it is used. Notes for the different architectures touched: arm - we use an already exported symbol cris - we use a config symbol aleady available [Not build tested] mips - the jiffies complexity has moved to vmlinux.lds.S where we need it. Added a few variables to CPPFLAGS - they are only used by the linker script. [Not build tested] powerpc - removed assignment that is not needed [not build tested] sparc - simplified it using $(BITS) um - introduced a few new exported variables to deal with this xtensa - added options to CPP invocation [not build tested] Cc: Albin Tonnerre <albin.tonnerre@free-electrons.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Mikael Starvik <starvik@axis.com> Cc: Jesper Nilsson <jesper.nilsson@axis.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Cc: "David S.

* ctags: usability fixStefani Seibold2009-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | The tag file generated by the tags.sh script has some issue. First: The identifier-list miss the DEFINE_TRACE,EXPORT_TRACEPOINT_SYMBOL,EXPORT_TRACEPOINT_SYMBOL_GPL special handling, which can result in a wrong tag, not to jump to the right variable definition or function implementation. Second: It makes no real sense to include function prototypes and external and forward variable declarations, because jumping to a tag will sometimes go to this and not to the real definition and implementation. The information about the declaration is still there at the definition and implementation place. So this patch make it lot easier to navigate through the kernel source tree using vi.

* kbuild: save ARCH & CROSS_COMPILE when building a kernelSam Ravnborg2009-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building a kernel for a different architecture kbuild requires the user always to specify ARCH and CROSS_COMPILE on the command-line. We use the asm symlink to detect if user forgets to specify the correct ARCH value - but that symlink is about to die. And we do now want to loose this check. This patch save the settings of ARCH and CROSS_COMPILE in two files named: include/generated/kernel.arch include/generated/kernel.cross The settings are saved during "make *config" time and always read. If user try to change the settings we error out. This works both for plain builds and for O=... builds. So now you can do: $ mkdir sparc64 $ make O=sparc64 ARCH=sparc64 CROSS_COMPILE=sparc64-linux- defconfig $ cd sparc64 $ make Notice that you no longer need to tell kbuild the settings of ARCH and CROSS_COMPILE when you type make in the output directory. Likewise for plain builds where you do not use O=... Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roland McGrath <roland@redhat.com>
* kbuild: use INSTALLKERNEL to select customized installkernel scriptSam Ravnborg2009-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the use of CROSS_COMPILE to select a customized installkernel script with the possibility to set INSTALLKERNEL to select a custom installkernel script when running make: make INSTALLKERNEL=arm-installkernel install With this patch we are now more consistent across different architectures - they did not all support use of CROSS_COMPILE. The use of CROSS_COMPILE was a hack as this really belongs to gcc/binutils and the installkernel script does not change just because we change toolchain. The use of CROSS_COMPILE caused troubles with an upcoming patch that saves CROSS_COMPILE when a kernel is built - it would no longer be installable. [Thanks to Peter Z. for this hint] This patch undos what Ian did in commit: 0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46 ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh") The patch has been lightly tested on x86 only - but all changes looks obvious.

There is a much simpler solution. Most i8259 specific functions are already called dependend on the irq number less than NR_IRQS_LEGACY. Replacing that constant by a read_mostly variable which can be set to 0 by the platform setup code allows us to achieve the same without any special feature flags. That trivial change allows us to proceed with MRST w/o doing a full blown overhaul of the ioapic code which would delay MRST unduly. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | Platforms like Moorestown require early setup and want to avoid the call to reserve_ebda_region. The x86_init override is too late when the MRST detection happens in setup_arch. Move the default i386 x86_init overrides and the call to reserve_ebda_region into a separate function which is called as the default of a switch case depending on the hardware_subarch id in boot params.

| | | | | | | | | | | | | | | | | | | | We do not need the TSC before late_time_init. Move the tsc_init to the late time init code so we can also utilize HPET for calibration (which we claimed to do but never did except in some older kernel version).

| * x86: Simplify timer_ack magic in time_32.cThomas Gleixner2009-08-31
| | | | | | | | | | | | | | | | | | Let the compiler optimize the timer_ack magic away in the 32bit timer interrupt and put the same code into time_64.c. It's optimized out for CONFIG_X86_IO_APIC on 32bit and for 64bit because timer_ack is const 0 in both cases. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
| * x86: Prepare unification of time_32/64.cThomas Gleixner2009-08-31
| | | | | | | | | | | | Unify the top comment and the includes. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
| * x86: Remove do_timer hookThomas Gleixner2009-08-31
| | | | | | | | | | | | | | This is a left over of the old x86 sub arch support. Remove it and open code it like we do in time_64.c Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
| * x86: Add timer_init to x86_init_opsThomas Gleixner2009-08-31
| | | | | | | | | | | | | | | | | | | | | | | | The timer init code is convoluted with several quirks and the paravirt timer chooser. Figuring out which code path is actually taken is not for the faint hearted. Move the numaq TSC quirk to tsc_pre_init x86_init_ops function and replace the paravirt time chooser and the remaining x86 quirk with a simple x86_init_ops function.

| * x86: Move percpu clockevents setup to x86_init_opsThomas Gleixner2009-08-31
| | | | | | | | | | | | | | | | | | | | paravirt overrides the setup of the default apic timers as per cpu timers. Moorestown needs to override that as well. Move it to x86_init_ops setup and create a separate x86_cpuinit struct which holds the function for the secondary evtl. hotplugabble CPUs. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
