Roland Dreier reported in http://lkml.org/lkml/2008/2/27/194 [ 8425.915139] BUG: unable to handle kernel paging request at ffffc20001a0a000 [ 8425.919087] IP: [<ffffffff8021dacc>] clflush_cache_range+0xc/0x25 [ 8425.919087] PGD 1bf80e067 PUD 1bf80f067 PMD 1bb497067 PTE 80000047000ee17b 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. Signed-off-by:

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. Signed-off-by: -

early_init_intel() on 64-bit is introduced by commit 2b16a235 Author: Andi Kleen <ak@suse.de> Date: Wed Jan 30 13:32:40 2008 +0100 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.
