* x86: Add timer_init to x86_init_opsThomas Gleixner2009-08-311-15/+5
| | | | | | | | | | | | 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 traps_init to x86_init_opsThomas Gleixner2009-08-311-5/+3

* x86: Move irq_init to x86_init_opsThomas Gleixner2009-08-311-1/+0
| | | | | | | | | irq_init is overridden by x86_quirks and by paravirts. Unify the whole mess and make it an unconditional x86_init_ops function which defaults to the standard function and can be overridden by the early platform code. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* x86: Move pre_intr_init to x86_init_opsThomas Gleixner2009-08-311-7/+3
| | | | | | | | | Replace the quirk machinery by a x86_init_ops function which defaults to the standard implementation. This is also a preparatory patch for Moorestown support which needs to replace the default init_ISA_irqs as well. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

* x86: Move memory_setup to x86_init_opsThomas Gleixner2009-08-271-1/+2
| | | | | | | | | memory_setup is overridden by x86_quirks and by paravirts with weak functions and quirks. Unify the whole mess and make it an unconditional x86_init_ops function which defaults to the standard function and can be overridden by the early platform code.

* x86: refactor x86_quirks supportIngo Molnar2009-02-231-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | Impact: cleanup Make x86_quirks support more transparent. The highlevel methods are now named: extern void x86_quirk_pre_intr_init(void); extern void x86_quirk_intr_init(void); extern void x86_quirk_trap_init(void); extern void x86_quirk_pre_time_init(void); extern void x86_quirk_time_init(void); This makes it clear that if some platform extension has to do something here that it is considered ... weird, and is discouraged. Also remove arch_hooks.h and move it into setup.h (and other header files where appropriate). Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86: rename all fields of mpc_cpu mpc_X to XJaswinder Singh Rajput2009-01-051-15/+13
| | | | | | | | | | | | Impact: cleanup, solve 80 columns wrap problems It would be cleaner to rename all the mpc->mpc_X fields to mpc->X - that alone would give 4 characters per usage site. (we already know that it's an 'mpc' entity - no need to duplicate that in the field too) Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: rename mpc_config_processor to mpc_cpuJaswinder Singh Rajput2009-01-041-2/+2
| | | | | | | | | | | | | | | Impact: cleanup, solve 80 columns wrap problems mpc_config_processor should be renamed to mpc_cpu. The reason: the 'c' in MPC already means 'config' - no need to repeat that in the type name. Plus 'processor' is a lot longer than 'cpu' - so we try to use 'cpu' in all type names, as much as possible.

| | | | | | | | | | | | | | | | | | irq_desc[] add CONFIG_HAVE_SPARSE_IRQ to for use condensed array. Get rid of irq_desc[] array assumptions. Preallocate 32 irq_desc, and irq_desc() will try to get more. ( No change in functionality is expected anywhere, except the odd build failure where we missed a code site or where a crossing commit itroduces new irq_desc[] usage. ) v2: according to Eric, change get_irq_desc() to irq_desc() Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| * x86: resurrect proper handling of maxcpus= kernel option (v2)Max Krasnyansky2008-08-141-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some reason we had two parsers registered for maxcpus=. One in init/main.c and another in arch/x86/smpboot.c. So I nuked the one in arch/x86. Also 64-bit kernels used to handle maxcpus= as documented in Documentation/cpu-hotplug.txt. CPUs with 'id > maxcpus' are initialized but not booted. 32-bit version for some reason ignored them even though all the infrastructure for booting them later is there. In the current mainline both 64 and 32 bit versions are broken. This patch restores the correct behaviour. I've tested x86_64 version on 4- and 8- way Core2 and 2-way Opteron based machines. Various config combinations SMP, !SMP, CPU_HOTPLUG, !CPU_HOTPLUG. Booted with maxcpus=1 and maxcpus=4, etc. Everything is working as expected. So far we've received two reports from different people confirming that 32-bit version also works fine, both on dual core laptops and 16way server machines.
