43f39890db x86: seperate default_send_IPI_mask_sequence/allbutself from logical
Impact: 32-bit should use logical version

there are two version: for default_send_IPI_mask_sequence/allbutself
one in ipi.h and one in ipi.c for 32bit

it seems .h version overwrote ipi.c for a while.

restore it so 32 bit could use its old logical version.
also remove dupicated functions in .c

5872fb94f8 Documentation: move DMA-mapping.txt to Doc/PCI/
Move DMA-mapping.txt to Documentation/PCI/.

DMA-mapping.txt was supposed to be moved from Documentation/ to
Documentation/PCI/.  The 00-INDEX files in those two directories
were updated, along with a few other text files, but the file
itself somehow escaped being moved, so move it and update more
text files and source files with its new location.

550fe4f198 x86/Voyager: remove X86_FIND_SMP_CONFIG Kconfig quirk
x86/Voyager had this Kconfig quirk:

 config X86_FIND_SMP_CONFIG
	def_bool y
	depends on X86_MPPARSE || X86_VOYAGER

Which splits off the find_smp_config() callback into a build-time quirk.

Voyager should use the existing x86_quirks.mach_find_smp_config() callback
to introduce SMP-config quirks. NUMAQ-32 and VISWS already use this.

c0b5842a45 x86: generalize boot_cpu_id
x86/Voyager can boot on non-zero processors. While that can probably
be fixed by properly remapping the physical CPU IDs, keep boot_cpu_id
for now for easier transition - and expand it to all of x86.

3e5095d152 x86: replace CONFIG_X86_SMP with CONFIG_SMP
The x86/Voyager subarch used to have this distinction between
 'x86 SMP support' and 'Voyager SMP support':

 config X86_SMP
	bool
	depends on SMP && ((X86_32 && !X86_VOYAGER) || X86_64)

This is a pointless distinction - Voyager can (and already does) use
smp_ops to implement various SMP quirks it has - and it can be extended
more to cover all the specialities of Voyager.

So remove this complication in the Kconfig space.
