deselecting one of the CPU type CONFIG_CPU_SUP_* config options
can render a kernel unbootable. Make sure this option is only
available if CONFIG_EMBEDDED is enabled.

header_assemble
We lock GlobalMid_Lock in header_assemble and then immediately unlock it
again without doing anything. Not sure what this was intended to do, but
remove it.

Move the prototypes from the generic kernel.h header to the more
appropriate include/asm-x86/bios_ebda.h header file.
Also, remove the check from the power management code - this is a
pure x86 matter for now.

This adds a user_regset type for the x86 io permissions bitmap.
This makes it appear in core dumps (when ioperm has been used).
It will also make it visible to debuggers in the future.

Do not crash when enumerating supported CPU architectures
SECURITY_INIT somehow ended up in x86_cpu_dev.init section. That caused printk
in code which prints supported architectures to hit #GP due to non-canonical
address being used.

The x86 implementation of early_ioremap has an off by one error. If we get
an object which ends on the first byte of a page we undermap by one page and
this causes a crash on boot with the ASUS P5QL whose DMI table happens to fit
this alignment.
The size computation is currently
last_addr = phys_addr + size - 1;
npages = (PAGE_ALIGN(last_addr) - phys_addr)
(Consider a request for 1 byte at alignment 0...)

The variable 'scratch' is always initialized before it's used. The
conditional which is responsible for initialization of 'scratch' will
always evaluate 'true' when the first loop iteration occurs, and thus,
it's properly initialized. GCC doesn't see this, of course, so using
the uninitialized_var() macro seems to work for silencing this case.

Make sure we can be woken from the forced sleep that is done on errors.
Removing a card often results in -ENOMEDIUM or -EILSEQ so we previously
locked up the removal process for a second.
We could completely exit on -ENOMEDIUM, but it might be a transient
glitch so treat it like any other error.

The card detection delay was added early when the behaviour of the
card interrupt was still very much unknown (i.e. before there was a
public specification). As it is now known that it is a debounced signal,
reduce the delay to something more sensible.

Linus noted a build failure case:
net/netfilter/ipvs/ip_vs_xmit.c: In function 'ip_vs_tunnel_xmit':
net/netfilter/ipvs/ip_vs_xmit.c:616: error: implicit declaration of function 'ip_select_ident'
The proper include file (net/ip.h) is being included in ip_vs_xmit.c to get
that declaration. So the only possible case where this can happen is if
CONFIG_INET is not enabled.
This seems to be purely a missing dependency in the ipvs/Kconfig file IP_VS
entry.
Also, while we're here, remove the out of date "EXPERIMENTAL" string in the
IP_VS config help header line. IP_VS no longer depends upon CONFIG_EXPERIMENTAL
