<title>x86_64: Don't rely on a unique IO-APIC ID</title>

<id>urn:sha1:78b599aed61a1098444558e74c93745f22eda6cb</id>
<content type='text'>
Linux 64bit only uses the IO-APIC ID as an internal cookie. In the future
there could be some cases where the IO-APIC IDs are not unique because
they share an 8 bit space with CPUs and if there are enough CPUs
it is difficult to get them that. But Linux needs the io apic ID
internally for its data structures. Assign unique IO APIC ids on
table parsing.

TBD do for 32bit too

<content type='text'>
Remove includes of &lt;linux/smp_lock.h&gt; where it is not used/needed.
Suggested by Al Viro.

Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc,
sparc64, and arm (all 59 defconfigs).

Default to physical mode on hotplug CPU kernels.  Furher simplify and clean up
the APIC initialization code.

Fix the following section mismatch warnings on x86_64:

But adds:
WARNING: arch/x86_64/kernel/built-in.o - Section mismatch: reference to .init.text:get_mtrr_state from .text between 'mtrr_bp_init' (at offset 0xb887) and 'ipi_handler'

The warnings does not show up during a normal build due to kbuild
failing to check for section mismatch in vmlinux.
To see these warnings run:
scripts/mod/modpost arch/x86_64/kernel/built-in.o

kbuild will be fixed but the 'noise-level' had to be decresed first.
There remains a few section mismatch warnigns for x86_64 for areas where I did
not feel confident.
