x86: defconfig updates
changed CONFIG_RELOCATABLE from n to y, which may lead to a mismatch
between the vmlinux debug information and the runtime location of the
kernel, even when the bootloader does not relocate the kernel.
Revert the specific change. Works for me with GRUB and qemu.

Impact: double the defconfig printk buffer
Booting defconfigs produces more output than 128K so the output is
truncated - double it to 256K.

This has been deprecated for years, the user space irqbalanced utility
works better with numa, has configurable policies, etc...

The Winchip-2 and Winchip-2A cpu choices select the
same options for kernel and compiler.
Merge them to save few bytes and reduce confusion.

Additional updates to the x86 defconfigs. The goals are, as before:
- Make them usable to testers, more so than distributors or end users,
both of which are likely to have their own config already.
- Keep 32 and 64 bits as similar as is practical.
Changes:
- Use a more generic CPU type (ppro and generic, respectively).
- Bump number of CPUs to 64 (few if any NR_CPUS arrays left).
- Enable PAT.
- Enable OPTIMIZE_INLINE.
- Enable microcode update support.
- Build SMT scheduler support (in addition to MC).

Impact: cleanup
Video mode selection became always possible in 2.6.23-rc1 after i386 setup
code rewrite in C.
Regardless, VIDEO_SELECT is stupid config option because it affects only
kernel setup code, not code which always stays in memory.
vga= always possible now which is good.

Enable some option commonly used by testers in defconfig, including
some very common device drivers and network boot support. defconfig
is still not meant to be a kitchen-sink configuration.

CONFIG_NONPROMISC_DEVMEM was a rather confusing name - but renaming it
to CONFIG_PROMISC_DEVMEM causes problems on architectures that do not
support this feature; this patch renames it to CONFIG_STRICT_DEVMEM,
so that architectures can opt-in into it.
( the polarity of the option is still the same as it was originally; it
needs to be for now to not break architectures that don't have the
infastructure yet to support this feature)

refresh 32-bit defconfig too, and update the 64-bit configs as well,
the defconfig should be much more useful by default, so most of the
updates are the enabling of various options.

add CONFIG_OPTIMIZE_INLINING=y.
allow gcc to optimize the kernel image's size by uninlining
functions that have been marked 'inline'. Previously gcc was
forced by Linux to always-inline these functions via a gcc
attribute:
#define inline inline __attribute__((always_inline))
Especially when the user has already selected
CONFIG_OPTIMIZE_FOR_SIZE=y this can make a huge difference in
kernel image size (using a standard Fedora .config):
text data bss dec hex filename
5613924 562708 3854336 10030968 990f78 vmlinux.before
5486689 562708 3854336 9903733 971e75 vmlinux.after
that's a 2.3% text size reduction (!).

With some small changes to kconfig makefile we can now
locate the defconfig files for i386 and x86_64 in
the configs/ subdirectory under x86.
make ARCH=i386 defconfig and make defconfig
works as expected also after this change.
But arch maintainers shall now update a defconfig file in
the configs/ directory.
