3def3d6ddf x86: clean up e820_reserve_resources on 64-bit
e820_resource_resources could use insert_resource instead of request_resource
also move code_resource, data_resource, bss_resource, and crashk_res
out of e820_reserve_resources.

322850af8d x86: make amd quad core 8 socket system not be clustered_box, #2
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

Marking TSC unstable due to TSCs unsynchronized

even the CPUs have X86_FEATURE_CONSTANT_TSC set.

this patch will check if the cpu is from AMD.

bc0a733fac x86: define outb_pic and inb_pic to stop using outb_p and inb_p
x86: define outb_pic and inb_pic to stop using outb_p and inb_p

The delay between io port accesses to the PIC is now defined using outb_pic
and inb_pic.  This fix provides the next step, using udelay(2) to define the
*PIC specific* timing requirements, rather than on bus-oriented timing, which
is not well calibrated.

Again, the primary reason for fixing this is to use proper delay strategy,
and in particular to fix crashes that can result from using port 80 writes
on machines that have resources on port 80, such as the ENE chips used by Quanta
in latops it designs and sells to, e.g. HP.

04aaa7ba09 x86: fix cmos read and write to not use inb_p and outb_p
fix code to access CMOS rtc registers so that it does not use inb_p and
outb_p routines, which are deprecated.  Extensive research on all known
CMOS RTC chipset timing shows that there is no need for a delay in
accessing the registers of these chips even on old machines. These chipa
are never on an expansion bus, but have always been "motherboard"
resources, either in the processor chipset or explicitly on the
motherboard, and they are not part of the ISA/LPC or PCI buses, so
delays should not be based on bus timing. The reason to fix it:

 1) port 80 writes often hang some laptops that use ENE EC chipsets,
    esp. those designed and manufactured by Quanta for HP;

 2) RTC accesses are timing sensitive, and extra microseconds may matter;

 3) the new "io_delay" function is calibrated by expansion bus timing needs,
    thus is not appropriate for access to CMOS rtc registers.

03ae5768b6 x86: use ELF section to list CPU vendor specific code
Replace the hardcoded list of initialization functions for each CPU
vendor by a list in an ELF section, which is read at initialization in
arch/x86/kernel/cpu/cpu.c to fill the cpu_devs[] array. The ELF
section, named .x86cpuvendor.init, is reclaimed after boot, and
contains entries of type "struct cpu_vendor_dev" which associates a
vendor number with a pointer to a "struct cpu_dev" structure.

This first modification allows to remove all the VENDOR_init_cpu()
functions.

This patch also removes the hardcoded calls to early_init_amd() and
early_init_intel(). Instead, we add a "c_early_init" member to the
cpu_dev structure, which is then called if not NULL by the generic CPU
initialization code. Unfortunately, in early_cpu_detect(), this_cpu is
not yet set, so we have to use the cpu_devs[] array directly.

This patch is part of the Linux Tiny project, and is needed for
further patch that will allow to disable compilation of unused CPU
support code.

28d2312881 x86: reducing debuginfo size by removing unneeded includes
I found it strange that the struct sk_buff definition was found
inside the DWARF debugging sections in the generated object, so I verified
and found that there is no need for the files that bring struct sk_buff
definition into this file and verified also that sk_buff is not brought
in indirectly too, thru other headers.

	I went on and removed many other unneeded includes and the end
result is:

[acme@doppio net-2.6]$ l /tmp/sys_ia32.o.before /tmp/sys_ia32.o.after
-rw-rw-r-- 1 acme acme 185240 2008-02-06 19:19 /tmp/sys_ia32.o.after
-rw-rw-r-- 1 acme acme 248328 2008-02-06 19:00 /tmp/sys_ia32.o.before

	Almost 64KB only on this object file!

	There were no other side effects from this change:

[acme@doppio net-2.6]$ objcopy -j "text" /tmp/sys_ia32.o.before /tmp/text.before
[acme@doppio net-2.6]$ objcopy -j "text" /tmp/sys_ia32.o.after /tmp/text.after
[acme@doppio net-2.6]$ md5sum /tmp/text.before /tmp/text.after
b7ac9b17942add68494e698e4f965d36  /tmp/text.before
b7ac9b17942add68494e698e4f965d36  /tmp/text.after

	One of the complaints about using tools such as systemtap is
that one has to install the huge kernel-debuginfo package:

[acme@doppio net-2.6]$ rpm -q --qf "%{size}\n" kernel-rt-debuginfo
471737710
543867594
[acme@doppio net-2.6]$
