This patch adds explicit detection of the EBDA and reservation of the rom and adapter address space 0xa0000-0x100000 to the i386 kernels. Before this patch, the EBDA size was hardcoded as 4Kb. Also, the reservation of the adapter range was done by modifying the e820 map which is now not necessary any longer, and that code is removed from copy_e820_map. The amount of conventional memory and the start of the EBDA are detected by reading the BIOS data area directly. Paravirtual environments do not provide this area, so we bail out early in that case. They will just have to set up a correct memory map to start with. Signed-off-by:

The proper dependency check uncovered a few dependency problems, the subarchitecture used a mixture of selects and depends on SMP and PCI dependency was messed up. Signed-off-by:

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. 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: -

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.
