x86: X86_HT always enable on X86_64 SMP
...
X86_HT is used for hyperthreading or multicore on 32-bit.
The X86_HT on 64-bit is different from 32-bit, it means hyperthreading only.
And X86_HT is not used on 64-bit except from cpu/initel_cacheinfo.c.
Unify X86_HT for hyperthreading or multicore.
Turn X86_HT on when X86_64 and SMP are enabled.

[ 8425.915139] BUG: unable to handle kernel paging request at ffffc20001a0a000

This is on a Intel machine with 36bit physical address space. The PTE
entry references 47000ee000, which is outside of it.
Add a check for the physical address space and warn/printk about the
stupid caller.

x86, tracing: add notrace to asm-x86/linkage.h
...
notrace signals that a function should not be traced. Most of the
time this is used by tracers to annotate code that cannot be
traced - it's in a volatile state (such as in user vdso context
or NMI context) or it's in the tracer internals.

x86: move X86_FEATURE_CONSTANT_TSC into early cpu feature detection
sets CONSTANT_TSC for intel cpus - but it is already set in init_intel().
don't need to set that two times in early_init_intel() and init_intel().
this patch removes the init_intel() one.

quad core 8 socket system will have apic id lifting.the apic id range could
be [4, 0x23]. and apic_is_clustered_box will think that need to three clusters
and that is larger than 2. So it is treated as a clustered_box.
and will get:
Marking TSC unstable due to TSCs unsynchronized
even if the CPUs have X86_FEATURE_CONSTANT_TSC set.
this quick fix will check if the cpu is from AMD.
but vsmp still needs that checking...
this patch is fix to make sure that vsmp not to be passed.

found one entry about reserved is missing for the kernel by kexec.
it turns out init_apic_mappings is called before e820_reserve_resources
in setup_arch. but e820_reserve_resources is using request_resource.
it will not handle the conflicts.
there are three ways to fix it:
1. change request_resource in e820_reserve_resources to to insert_resource
2. move init_apic_mappings after e820_reserve_resources
3. use late_initcall to insert lapic resource.
this patch is using method 3, that is less intrusive.
in later version could consider to use method 1.
before patch
fed20000-ffffffff : PCI Bus #00
fee00000-fee00fff : Local APIC
fefff000-feffffff : pnp 00:09
ff700000-ffffffff : reserved
with patch will get map in first kernel

fee00000-fee00fff : Local APIC
fee00000-fee00fff : reserved
fefff000-feffffff : pnp 00:09

quad core 8 socket system will have apic id lifting.the apic id range could
be [4, 0x23]. and apic_is_clustered_box will think that need to three clusters
and that is large than 2. So it is treated as clustered_box.
and will get
