TSC calibration is modified by the vmware hypervisor and paravirt by separate means. Moorestown wants to add its own calibration routine as well. So make calibrate_tsc a proper x86_init_ops function and override it by paravirt or by the early setup of the vmware hypervisor. Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

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.

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: NThomas Gleixner <tglx@linutronix.de>

Replace another obscure paravirt magic and move it to x86_init_ops. Such a hook is also useful for embedded and special hardware. Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

ARCH_SETUP is a horrible leftover from the old arch/i386 mach support code. It still has a lonely user in xen. Move it to x86_init_ops. Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

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: NThomas Gleixner <tglx@linutronix.de>

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: NThomas Gleixner <tglx@linutronix.de>

32bit and also the numaq code have special requirements on the ioapic_id setup. Convert it to a x86_init_ops function and get rid of the quirks and #ifdefs Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

The x86 quirkification introduced an extra ugly hackery with a variable pointer in the mpparse code. If the pointer is initialized then it is dereferenced and the variable set to 0 or incremented. Create a x86_init_ops function and let the affected numaq code hold the function. Default init is a setup noop. Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

The 32bit and the 64bit code are slighty different in the reservation of standard resources. Also the upcoming Moorestown support needs its own version of that. Add it to x86_init_ops and initialize it with the 64bit default. 32bit overrides it in early boot. Now moorestown can add it's own override w/o sprinkling the code with more #ifdefs Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

probe_roms is only used on 32bit. Add it to the x86_init ops and remove the #ifdefs. Default initializer is x86_init_noop() which is overridden in the 32bit boot code. Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

The upcoming Moorestown support brings the embedded world to x86. The setup code of x86 has already a couple of hooks which are either x86_quirks or paravirt ops. Some of those setup hooks are pretty convoluted like the timer setup and the tsc calibration code. But there are other places which could do with a cleanup. Instead of having inline functions/macros which are modified at compile time I decided to introduce x86_init ops which are unconditional in the code and make it clear that they can be changed either during compile time or in the early boot process. The function pointers are initialized by default functions which can be noops so that the pointer can be called unconditionally in the most cases. This also allows us to remove 32bit/64bit, paravirt and other #ifdeffery. paravirt guests are just a hardware platform in the setup code, so we should treat them as such and not hide all behind multiple layers of indirection and compile time dependencies. It's more obvious that x86_init.timers.timer_init() is a function pointer than the late_time_init = choose_time_init() obscurity. It's also way simpler to grep for x86_init.timers.timer_init and find all the places which modify that function pointer instead of analyzing weak functions, macros and paravirt indirections. Note. This is not a general paravirt_ops replacement. It just will move setup related hooks which are potentially useful for other platform setup purposes as well out of the paravirt domain. Add the base infrastructure without any functionality. Signed-off-by: NThomas Gleixner <tglx@linutronix.de>
